Mexico oil firm blast caused by gas build-up: official

MEXICO CITY: The explosion that killed 37 people at the headquarters of Mexico's state-owned oil firm was caused by a gas build-up, officials said Monday, ruling out a bomb attack.

The announcement ended a four-day-long mystery that had sparked a wave of speculation about the cause of the blast at the complex that houses the offices of Pemex in the heart of Mexico City.

The explosion tore through an annex of the company's skyscraper in the capital last Thursday, injuring more than 120 people.

"We were able to determine that the explosion was caused by an accumulation of gas in the basement" of the annex, Attorney General Jesus Murillo Karam told a news conference.

The blast caused floors to collapse, killing 37 people, he said.

"We confirmed that there are no traces of explosives," he said, adding that the blast did not leave a crater and that the victims did not have the type of dismemberment caused by bombs.

Hackers hit U.S. Department of Energy

The U.S. Department of Energy said that hackers have stolen personal data of its employees and contractors.

The U.S. Department of Energy has confirmed that its computer systems were hacked into last month. According to The New York Times, the federal agency sent around an internal e-mail on Friday telling its employees about the cyberattack.

"The Department of Energy has just confirmed a recent cyber incident that occurred in mid-January which targeted the Headquarters' network and resulted in the unauthorized disclosure of employee and contractor Personally Identifiable Information," the e-mail said.

The agency said that it is working to figure out the "nature and scope of the incident" but that so far it believes "no classified data was compromised." It's unclear which divisions within the Department of Energy were attacked or who was behind the hack.

The Department of Energy is in charge of much of the country's vital infrastructure, such as energy production, nuclear reactor production, and radioactive waste disposal. It has troves of classified and sensitive data that if leaked could be detrimental to the country's security. According to Reuters, the most highly classified information is stored on networks that aren't connected to the Internet.

The head of Homeland Security Janet Napolitano recently announced that she believes a wave of cyberattacks on U.S. infrastructure is a serious possibility. Dubbing such an event a "cyber 9/11," Napolitano warned that cyberterrorists could take down the nation's power grid, water infrastructure, transportation networks, and financial networks.

While it doesn't seem like the January cyberattack on the Department of Energy compromised any data or infrastructure, it does show that hackers were able to breach the government's computer systems. In the e-mail, the agency said it is working to fortify itself against future attacks.

"Once the full nature and extent of this incident is known, the Department will implement a full remediation plan," the e-mail said. "The Department is also leading an aggressive effort to reduce the likelihood of these events occurring again. These efforts include leveraging the combined expertise and capabilities of the Department's Joint Cybersecurity Coordination Center to address this incident, increasing monitoring across all of the Department's networks and deploying specialized defense tools to protect sensitive assets."

CNET contacted the Department of Energy for comment. We'll update the story when we get more information.

Crashed bus owner failed one-third of safety inspections

YUCAIPA, Calif. The company linked to a tour bus involved in a deadly crash in Southern California failed more than a third of federal vehicle safety inspections in the last two years.

Calif. tour bus crash kills at least 8

Tour bus crashes in Calif.

U.S. government records show that buses operated by the firm Scapadas Magicas of National City, Calif., flunked 36 percent of random inspections on their vehicles — in some cases for brake and tire problems.

That's higher than the national average for similar companies — a 21 percent failure rate.

Records also show the company had no crashes in the past two years.

The California company had an overall "satisfactory" rating from the Federal Motor Carrier Safety Administration, but records show three-quarters of similar companies had better safety records.

Lettering on the 1996 bus indicates it was operated by Scapadas Magicas.

At least seven people were killed in Sunday night's crash. More than three dozen people were injured, and at least 17 were still hospitalized, including at least five in critical condition. One is a girl.

Authorities lowered the death count from 8 to 7 on Monday.

The cause of the crash remains under investigation. The National Transportation Safety Board was sending a team to the scene.

CBS Station KCBS reports that the bus, carrying dozens of men, women and children from Tijuana, was on its way back to Mexico Sunday evening after a day in Big Bear when the driver lost control just after 6:30 p.m., about 60 miles east of Los Angeles.

Investigators say the bus flipped and landed on a pickup truck towing a trailer. A black Saturn was also rear-ended.

The crash left State Route 38 littered with body parts and debris, and the bus sideways across both lanes with its windows blown out, front end crushed and part of the roof peeled back like a tin can.

One person in the pickup truck was injured. The fate of the passengers in the car was not clear, but at least two people were in the Saturn, said California Highway Patrol spokesman Mario Lopez.

Investigators will determine if mechanical failure or driver error was to blame. The bus driver, who survived but was injured, told investigators the vehicle had brake problems.

"It appears speed was a factor in this collision," said Lopez.

Crews worked through the night to recover the dead, but one body remained aboard the bus early Monday, said Rocky Shaw, a San Bernardino County coroner's investigator.

Officials hadn't been able to retrieve the body because the front end of the bus was dangling over the edge of the roadside.

Boy Safe, Kidnapper Dead as Ala. Standoff Ends

A week-long standoff in Alabama, where a retired trucker held a 5-year-old boy hostage in an underground bunker, has ended with the kidnapper dead and the child safe, according to law enforcement.

With a SWAT team positioned near the bunker entrance, authorities used an explosive charge to help gain entry into the bunker and neutralize the suspect, Richard Lee Dykes, according to a law enforcement source with direct knowledge.

Officials had been able to insert a high-tech camera into the bunker to monitor Dykes' movements, and they had become increasingly concerned that he might act out, the source said.

"FBI agents safely recovered the child who's been held hostage for nearly a week," FBI Special Agent Steve Richardson said at a news conference.

The agent said negotiations with Dykes "deteriorated" in the past 24 hours.

"Mr. Dykes was observed holding a gun," Richardson said. "At this point, the FBI agents, fearing the child was in imminent danger, entered the bunker and rescued the child."

The boy, identified only as Ethan, "appears physically unharmed" and is being treated at a hospital, authorities said.

Dykes, 65, is dead, but officials have not yet provided details on how he died.

"Right now, FBI special agent bomb technicians are in the process of clearing the property for improvised explosive devices," the FBI said in a written statement. "When it is safe to do so, our evidence response teams, paired with state and local crime scene technicians, will process the scene."

Dykes allegedly shot and killed a school bus driver last week and threatened to kill all the children on the bus before taking the boy, one of the students on the bus said.

"He said he was going to kill us, going to kill us all," Tarrica Singletary, 14, told ABC News.

Dykes had been holed up in his underground bunker near Midland City, Ala., with the abducted boy for a week as police tried to negotiate with him through a PVC pipe. Police had used the talks to send the child comfort items, including a red Hot Wheels car, coloring books, cheese crackers, potato chips and medicine.

Dykes was a decorated Vietnam vet who grew up in the area. He lived in Florida until two years ago, the AP reported, and has an adult daughter, but the two lost touch years ago, neighbor Michael Creel said. When he returned to Alabama, neighbors say he once beat a dog with a lead pipe and had threatened to shoot children who set foot on his property.

Iran hedges on nuclear talks with six powers or U.S.

MUNICH (Reuters) - Iran said on Sunday it was open to a U.S. offer of direct talks on its nuclear program and that six world powers had suggested a new round of nuclear negotiations this month, but without committing itself to either proposal.

Diplomatic efforts to resolve a dispute over Iran's nuclear program, which Tehran says is peaceful but the West suspects is intended to give Iran the capability to build a nuclear bomb, have been all but deadlocked for years, while Iran has continued to announce advances in the program.

Iranian Foreign Minister Ali Akbar Salehi said a suggestion on Saturday by U.S. Vice President Joe Biden that Washington was ready for direct talks with Iran if Tehran was serious about negotiations was a "step forward".

"We take these statements with positive consideration. I think this is a step forward but ... each time we have come and negotiated it was the other side unfortunately who did not heed ... its commitment," Salehi said at the Munich Security Conference where Biden made his overture a day earlier.

He also complained to Iran's English-language Press TV of "other contradictory signals", pointing to the rhetoric of "keeping all options on the table" used by U.S. officials to indicate they are willing to use force to keep Iran from obtaining a nuclear weapon.

"This does not go along with this gesture (of talks) so we will have to wait a little bit longer and see if they are really faithful this time," Salehi said.

Iran is under a tightening web of sanctions. Israel has also hinted it may strike if diplomacy and international sanctions fail to curb Iran's nuclear drive.

In Washington, Army General Martin Dempsey, the top U.S. military officer, said in an interview broadcast on Sunday that the United States has the capability to stop any Iranian effort to build nuclear weapons, but Iranian "intentions have to be influenced through other means."

Dempsey, chairman of the Joint Chiefs of Staff, made his comments on NBC's program "Meet the Press," speaking alongside outgoing Defense Secretary Leon Panetta.

Panetta said current U.S. intelligence indicated that Iranian leaders have not made a decision to proceed with the development of a nuclear weapon.

"But every indication is they want to continue to increase their nuclear capability," he said. "And that's a concern. And that's what we're asking them to stop doing."

The new U.S. secretary of state, John Kerry, has said he will give diplomacy every chance of solving the Iran standoff.

THE BEST CHANCE

With six-power talks making little progress, some experts say talks between Tehran and Washington could be the best chance, perhaps after Iran has elected a new president in June.

Negotiations between Iran and the six powers - Russia, China, the United States, Britain, France and Germany - have been deadlocked since a meeting last June.

EU officials have accused Iran of dragging its feet in weeks of haggling over the date and venue for new talks.

Salehi said he had "good news", having heard that the six powers would meet in Kazakhstan on February 25.

A spokesman for EU foreign policy chief Catherine Ashton, who coordinates the efforts of the six powers, confirmed that she had proposed talks in the week of February 25 but noted that Iran had not yet accepted.

Kazakhstan said it was ready to host the talks in either Astana or Almaty.

Salehi said Iran had "never pulled back" from the stuttering negotiations with the six powers. "We still are very hopeful. There are two packages, one package from Iran with five steps and the other package from the (six powers) with three steps."

Iran raised international concern last week by announcing plans to install and operate advanced uranium enrichment machines. The EU said the move, potentially shortening the path to weapons-grade material, could deepen doubts about the peaceful nature of Iran's nuclear program.

Prime Minister Benjamin Netanyahu said on Sunday that Israel's mission to stop its arch-enemy from acquiring nuclear weapons was "becoming more complex, since the Iranians are equipping themselves with cutting-edge centrifuges that shorten the time of (uranium) enrichment".

"We must not accept this process," said Netanyahu, who is trying to form a new government after winning an election last month. Israel is generally believed to be the only country in the Middle East with nuclear weapons.

Shackleton Antarctic bid makes landfall

SYDNEY: An exhausted British-Australian expedition recreating Ernest Shackleton's 1916 crossing of the Southern Ocean in a small boat made landfall Monday after a perilous 12-day journey.

Led by renowned adventurer Tim Jarvis, the team of six reached Peggotty Bluff on rugged South Georgia, where they landed their vessel in the same place Shackleton and his men beached the James Caird nearly 100 years ago.

The next leg will see three of the team tackle a two-day climb to 900 metres (2,950 feet) over the mountainous, crevassed interior of South Georgia.

That will take them to the old whaling station at Stromness on the other side of the island, where Shackleton and his men, with little more than the clothes on their backs, raised the alarm about the sinking of their ship, the Endurance.

Jarvis said the boat trip, using only the equipment, navigational instruments and food available to Shackleton, was extremely tough, describing it as "truly about endurance -- mental as much as physical".

"There was just no way to keep dry. The waterproofing with wax didn't work," he said.

"Below deck, the boat was constantly damp and being on watch meant that you were directly exposed to the elements. On a few occasions a big wave washed over the deck and down the hatch soaking everything down below."

Along with Norway's Roald Amundsen, the first man to reach the South Pole in 1911, Australian explorer Douglas Mawson and Briton Robert Falcon Scott, Shackleton was among the great Antarctic explorers.

When he set off on his third trip to the region in 1914 with the ship Endurance, he planned to cross Antarctica via the South Pole.

But the vessel became trapped in 1915, and sank 10 months later as it was crushed by the advancing ice. Shackleton and his crew lived on the floating ice until April 1916, when they set off in three small boats for Elephant Island.

From there, Shackleton and five crew members made the treacherous voyage to South Georgia, reaching their destination 16 days later to face the mountainous trek.

All members of the Endurance mission were eventually rescued with no fatalities.

It was his granddaughter Alexandra who approached Jarvis, who in 2007 re-enacted Mawson's 1912 odyssey across the frozen continent, about recreating their ordeal.

Super Bowl play stopped for 34 minutes as Superdome lost power

As the second half got underway at the Super Bowl, old-fashioned technology got in the way of play. Power at the Superdome reportedly surged, knocking out a majority of lights as well as CBS' play-by-play announcers. According to Entergy, which supplies the power to the Superdome, the issue is on the "customer's side."

An outside power feed coming to the stadium got disrupted according to NFL officials, said CBS's announcer on the sidelines Steve Tasker. Play-by-play announcers Jim Nance and Phil Simms were off the air for more than 30 minutes. Power was restored and play resumed after a 34-minute delay.

The Twitter football fans watching the game had some fun while waiting for the game to resume:

Sandy Hook choir, Hudson delight Super Bowl crowd

NEW ORLEANS As 26 children in white polo shirts excitedly walked to center of the Superdome field and prepared to sing, a packed Super Bowl crowd revved up by a day of partying in the Big Easy fell silent.

The chorus from Sandy Hook Elementary School, nearly two months removed from a deadly shooting rampage, joined Jennifer Hudson to deliver a stirring rendition of "America the Beautiful" on Sunday that had some players on the sideline and countless fans in the stands on the verge of tears.

Judging by the responses on social media, the performance appeared destined to become one of the most poignant memories of the Super Bowl, regardless of what played out in the game.

"Sandy hook elementary chorus singing America the beautiful and Alicia keys national anthem makes me proud to be American," model Kate Upton said on her Twitter page.

Super Bowl XLVII highlights

Gerald Rokoff, standing near a portal in the Superdome's upper deck, turned and said, "Beyond beautiful," when the children finished singing.

Sandy Hook is the school in Newtown, Conn., where 20 first-graders and six adults were killed by a gunman on Dec. 14.

An NFL spokesman said no one with the chorus was available for interviews, but a statement was delivered on behalf of the school.

"We have come to New Orleans to represent the Sandy Hook Family and the community of Newtown, Connecticut," the statement said. "Our wish is to demonstrate to America and the world that, `We are Sandy Hook and We Choose Love."'

The children wore green ribbons on their white shirts, which seemed to symbolize the innocence of youth, and stood in two rows of 13 on the NFL's red, white and blue shield logo for the performance. Many smiled excitedly as they sang the first verse. Then Hudson, wearing a black blouse and long, white skirt, fronted them for a second verse that showcased her sterling voice.

Baltimore Ravens coach John Harbaugh watched with his left arm around daughter, Alison, and his right hand over his heart.

Ravens nose tackle Terrence Cody could be seen on the stadium's video board tilting his head back, appearing to hold back tears.

Fans offered a rousing ovation at the finish, and the chorus then trotted to the 20-yard line and turned, with their hands on their hearts, to watch Alicia Keys sing the national anthem.

Caitlin Hamilton, a 22-year-old English teacher from Dodge City, Kansas, said on Twitter she thought the performance would, without a doubt, be the best part of the Super Bowl.

"It just shows that they're still persevering despite what's happened to them," Hamilton said. "It was a great way to lift up the people of Sandy Hook as well, and to let them know that the people of America support them."

Hamilton said that as a teacher, when she thinks about the shooting she thinks of herself in the same situation. She said Hudson did well leading the song, but the kids were the main event.

"I thought the kids were more inspirational that they could get up there and sing despite everything that had happened to them," she said.

During the season, NFL stars including Victor Cruz of the Giants and Chris Johnson of the Titans honored victims of the Sandy Hook rampage during games by writing the names of the victims' on their shoes.

Turkey says tests confirm leftist bombed U.S. embassy

ISTANBUL (Reuters) - A member of a Turkish leftist group that accuses Washington of using Turkey as its "slave" carried out a suicide bomb attack on the U.S. embassy, the Ankara governor's office cited DNA tests as showing on Saturday.

Ecevit Sanli, a member of the leftist Revolutionary People's Liberation Army-Front (DHKP-C), blew himself up in a perimeter gatehouse on Friday as he tried to enter the embassy, also killing a Turkish security guard.

The DHKP-C, virulently anti-American and listed as a terrorist organization by the United States and Turkey, claimed responsibility in a statement on the internet in which it said Turkish Prime Minister Tayyip Erdogan was a U.S. "puppet".

"Murderer America! You will not run away from people's rage," the statement on "The People's Cry" website said, next to a picture of Sanli wearing a black beret and military-style clothes and with an explosives belt around his waist.

It warned Erdogan that he too was a target.

Turkey is an important U.S. ally in the Middle East with common interests ranging from energy security to counter-terrorism. Leftist groups including the DHKP-C strongly oppose what they see as imperialist U.S. influence over their nation.

DNA tests confirmed that Sanli was the bomber, the Ankara governor's office said. It said he had fled Turkey a decade ago and was wanted by the authorities.

Born in 1973 in the Black Sea port city of Ordu, Sanli was jailed in 1997 for attacks on a police station and a military staff college in Istanbul, but his sentence was deferred after he fell sick during a hunger strike. He was never re-jailed.

Condemned to life in prison in 2002, he fled the country a year later, officials said. Interior Minister Muammer Guler said he had re-entered Turkey using false documents.

Erdogan, who said hours after the attack that the DHKP-C were responsible, met his interior and foreign ministers as well as the head of the army and state security service in Istanbul on Saturday to discuss the bombing.

Three people were detained in Istanbul and Ankara in connection with the attack, state broadcaster TRT said.

The White House condemned the bombing as an "act of terror", while the U.N. Security Council described it as a heinous act. U.S. officials said on Friday the DHKP-C were the main suspects but did not exclude other possibilities.

Islamist radicals, extreme left-wing groups, ultra-nationalists and Kurdish militants have all carried out attacks in Turkey in the past.

SYRIA

The DHKP-C statement called on Washington to remove Patriot missiles, due to go operational on Monday as part of a NATO defense system, from Turkish soil.

The missiles are being deployed alongside systems from Germany and the Netherlands to guard Turkey, a NATO member, against a spillover of the war in neighboring Syria.

"Our action is for the independence of our country, which has become a new slave of America," the statement said.

Turkey has been one of the leading advocates of foreign intervention to end the civil war in Syria and has become one of President Bashar al-Assad's harshest critics, a stance groups such as the DHKP-C view as submission to an imperialist agenda.

"Organizations of the sectarian sort like the DHKP-C have been gaining ground as a result of circumstances surrounding the Syrian civil war," security analyst Nihat Ali Ozcan wrote in a column in Turkey's Daily News.

The Ankara attack was the second on a U.S. mission in four months. On September 11, 2012, U.S. Ambassador Christopher Stevens and three American personnel were killed in an Islamist militant attack on the U.S. Consulate in Benghazi, Libya.

The DHKP-C was responsible for the assassination of two U.S. military contractors in the early 1990s in protest against the first Gulf War, and it fired rockets at the U.S. consulate in Istanbul in 1992, according to the U.S. State Department.

It has been blamed for previous suicide attacks, including one in 2001 that killed two police officers and a tourist in Istanbul's central Taksim Square. It has carried out a series of deadly attacks on police stations in the last six months.

Friday's attack may have come in retaliation for an operation against the DHKP-C last month in which Turkish police detained 85 people. A court subsequently remanded 38 of them in custody over links to the group.
