LONDON — A wave of bomb threats against passenger airliners caused chaos in the skies and airports of Europe on Thursday, the latest of such incidents this week that have prompted emergency landings and security sweeps on runways.
No explosives have so far been found, and it is not clear who or what is behind the security threats made against at least 14 airliners. But the threats have caused disruption to Europe’s airspace and some of its busiest airports.
One of the first reports involved Aer Lingus Flight EI402 from Dublin to Rome, which changed course near Paris and diverted to a French air force base, the airline said. There, all 151 passengers and six crewmembers were evacuated while a bomb squad inspected the aircraft, French Prime Minister Sebastien Lecornu’s office said in a statement.

- Czech police say four unidentified flights headed for Prague have also received threats.
From there, reports of threats in the skies over Europe arrived at dizzying pace, triggering searches by cabin crews and then again by airport security once on the ground.
Security operations were launched at airports in Prague, Copenhagen and Warsaw, with passengers at the last seeing the military and police sniffer dogs patrolling the tarmac.
“It is too early to draw conclusions on whether the reported incidents are linked,” Apostolos Tzitzikostas, European commissioner for sustainable transport and tourism, told a news conference in Brussels, adding that “we don’t have information yet whether this is a cyber attack.”
A Finnair flight from Helsinki was escorted by Italian air force jets to Rome’s Fiumicino Airport “following anonymous reports of a suspected bomb threat,” according to a spokesperson for the city’s airport authority. Bomb disposal experts found nothing.
