Another Turkish Airlines flight - this one flying from Bangkok to Istanbul - has faced a bomb threat, with the plane landing at India's New Delhi's Indira Gandhi International Airport.
In April, a Turkish Airlines plane flying from Istanbul to Basel turned back over Bulgarian air space after the discovery of a written note warning of a bomb on board.
A month before that, a flight from Istanbul to Brazil made an emergency landing in Morocco after the crew found a written note in one of the plane's toilets warning of a bomb.
Despite comprehensive searches, nothing dangerous was found in any of the three affected aircraft.
