US warns airlines of al-Qaida hijack bids
The vague warning came from information gleaned from interviews of at least one al-Qaida prisoner as well as intercepted communications, said one intelligence official, speaking on condition of anonymity. The information was obtained in the last few weeks.
âWe continue to investigate this information to determine its level of credibility,â said Gordon Johndroe, spokesman for the Department of Homeland Security.
There was no specific information on any potential targets, nor did officials know who in al-Qaida might attempt any attacks. The officials said al-Qaida could launch strikes in the US or Europe. There was no specific date, only a general sense that an attack could take place in the late summer, officials said.
âThe intelligence community continues to receive information about al-Qaidaâs interest in using the commercial aviation system,â Mr Johndroe said. âBecause of this the Department of Homeland Security issued an advisory this weekend to the nationâs airlines and law enforcement personnel.â
The warning was not provided to the general public, but officials acknowledged its distribution in response to queries.
âWe advised airline and law enforcement personnel to take a look at all their practices and initiate additional measures they may feel are necessary,â Mr Johndroe said.
The information points toward a September 11-style attack using hijacked planes as weapons, rather than a traditional hijacking, officials said.
The national terrorist threat level remains at yellow, signifying an elevated risk of attacks. There was no immediate sign that officials would raise it to orange, signifying a higher risk. The highest alert status is red.
Congress, which ordered an overhaul of aviation security in the aftermath of the September 11 attacks, recently acted to fill some holes in the system.
House and Senate negotiators last week approved an agreement to arm cargo pilots. Congress last year voted to give weapons to passenger airline pilots but not their counterparts on cargo planes.
