A Turkish Airlines flight from Houston to Istanbul was diverted to Ireland on Sunday after crew members found the word "bomb" written on a napkin in the plane's bathroom, according to Irish police and an airline spokesperson.
Turkish Airlines flight TK34, carrying 209 passengers, was met by emergency services upon landing at Shannon airport, NBC News reports.
U.S. Passenger Erez Lieberman Aiden told NBC News that he was awoke mid-flight and asked to check his luggage for suspicious objects, but was not told why. After checking passengers' luggage, flight attendants then ripped the covers off the seats, "as if they were looking for something," he said.
The BBC reported the plane would remain parked until its scheduled flight time elapsed, when authorities would search the aircraft and speak to the crew.
