Al Qaeda may be planning another airline hijacking with Muslim terrorists from Chechnya armed with liquid explosives, according to a new FBI advisory.
Usama bin Laden's underlings have been planning such a strike for more than a year, and believe such a plot has a better chance of success with Chechens because they don't look like Arabs, an FBI source told the New York Post.
Airlines were alerted of the plot yesterday in an FBI advisory based on an interrogation of an Al Qaeda member recently captured in Chechnya.
The advisory was "a precautionary reminder" to airlines to be alert to a possible plot, the FBI source said.
The FBI advisory was sent to 18,000 state and local law enforcement agencies throughout the United States.
An earlier report on the plot by ABC News said the plans involve 10 to 20 men who fought in Chechnya's long-running civil war with Russia and who are already in the United States.
The men, armed with liquid explosives, would try to overwhelm a plane's crew from seats in the first-class cabin, ABC News said.
