Passengers on a flight to Riyadh from Madrid were evacuated on Thursday after a note in English that read "11:30 bomb" was found pinned to the inside of the aircraft with a knife, police said.
The captain of the Saudi Airlines flight SVA226, travelling from Madrid to the Saudi Arabian capital Riyadh, reported a "threat" on board and requested an evacuation.
"Security forces and rescue services are mobilized. The plane was isolated and passengers evacuated," a spokeswoman for AENA, the group that manages airports in Spain, told AFP.
The spokeswoman said the airport was operating normally while security forces were inspecting the plane.
