At least four flights in Europe were subjected to bomb threats on Tuesday after one on Monday, forcing some to divert and an airport in Poland to briefly close, although no confirmed devices were discovered.

A LOT flight from London bound for Warsaw's Chopin airport was diverted to nearby Modlin airport, which briefly closed while the aircraft was searched and later reopened after no device was found. A second Warsaw-bound flight, an SAS service from Copenhagen, landed at Chopin as scheduled.

A day earlier, a Wizz Air flight from London to Sofia was diverted to Budapest after receiving a bomb threat. In Murcia, Spain, parts of an airport were cordoned off after a threat reported on a Ryanair flight from Manchester proved to be a hoax, with no explosives found on board.
