Washington, Apr 29 (IANS): A flight carrying 45 passengers from Houston to Washington was diverted Wednesday after a message threatening a terror attack was found in the plane's washroom, officials said.

"A threatening message was written on a lavatory mirror on board Continental Airlines flight 3006 from Houston Intercontinental Airport (IAH) to Washington Dulles Airport (IAD)," the Transportation Security Administration (TSA) said in a statement.

The flight was then diverted to Piedmont Triad International Airport near Greensboro "out of an abundance of caution," and safely landed at 10:43 a.m, the TSA said.

The jet Embraer-145 with three crew members taxied to a remote location where all passengers were safely deboarded. The local law enforcement officials were questioning the passengers, Xinhua reported quoting a statement from Continental Airlines.

The incident occures a day after a Delta Airlines flight from French capital Paris to US city of Atlanta was diverted to an airport in Maine after a former Air Force member claimed having fake passport and explosives in his luggage.
