Government says security threat over

WASHINGTON -- The "specific and credible" terrorist threats that led to the cancellation of seven flights, including ones to the Super Bowl, have passed, and there are no plans to ground any more, government officials said Monday.\n"At this point we do not have any new threat report targeting specific flights like we did over the weekend," White House spokesman Scott McClellan said.\nSix international flights from the United Kingdom and France and Continental Airlines Flight 1519 from Washington to Houston, site of the Super Bowl, were grounded Sunday and Monday after security concerns were raised by the Homeland Security Department.\nHomeland Security Department spokesman Brian Roehrkasse said there was "specific and credible intelligence information suggesting that al Qaeda would attack these flights on those dates.\n"It wasn't as specific as to the method of attack," he said.\nThe cancellations were the first since December, when the nation's terror alert level was increased from elevated, or yellow, to high, or orange.\nA senior law enforcement official, speaking on condition of anonymity, said some themes continue to emerge from intelligence collection: al Qaeda is determined to mount another large-scale attack and remains highly interested in aviation and weapons of mass destruction.\nIt's possible, the official said, that the two attack methods could be combined in some fashion but no specific plot has been reported.\nThe Continental flight was the first domestic flight to be canceled. Roehrkasse declined to provide details about the nature of the threat but said the federal agency and Continental "worked closely on the matter."\nThe flight was scheduled to take off from Dulles International Airport outside Washington at 5:45 p.m. EST Sunday and arrive at Bush Intercontinental Airport at 8:10 p.m. CST.\nBritish Airways canceled Flight 223 from London to Dulles for Sunday and Monday and Flight 207 from London to Miami on Sunday. Air France canceled Flight 026 from Paris to Washington on Sunday and Monday.\nA British pilots' union official expressed concern Monday over what it called the "erratic" nature of the security intelligence leading to the flight cancellations.
