Seven passenger flights to European countries including Poland, Spain and Italy were inspected on Tuesday after receiving a series of alleged bomb threats.
No explosives have been found on any of the flights so far, and it remains unclear whether the incidents are connected.
The suspected threats have disrupted airport operations, with some flights diverted and airports temporarily closed.
In Poland, a LOT Polish Airlines flight carrying 181 people from London's Heathrow Airport was scheduled to land at Warsaw Chopin Airport but was diverted to Warsaw Modlin Airport following a bomb threat. Modlin Airport said the plane landed at 10:01 local time on Tuesday, prompting the airport to temporarily shut down. Normal operations have since resumed after security checks found no explosives.
A separate SAS Scandinavian Airlines flight travelling from Copenhagen, Denmark, to Warsaw also received a bomb threat. It was inspected upon landing at Warsaw Chopin Airport, and no explosives were discovered.
In Spain, a Ryanair flight from Manchester, UK, to Murcia in southeastern Spain received a bomb threat, and all 114 passengers and seven crew members disembarked for security screening after landing at their destination. The airport later returned to normal operations after local authorities confirmed that no explosives were on board.
Security checks were carried out in Italy, where two Ryanair planes arriving from Lisbon and Dublin landed safely at Rome's Fiumicino Airport after bomb threats were reported on board, local media reported.
The two planes, escorted by Italian Air Force fighter jets, landed at 9:40 and 10:44 respectively. Italian State Police bomb disposal experts subsequently searched the aircraft and passengers' luggage in accordance with security procedures.
The inspections were completed around noon, with no explosive devices or suspicious items found, and no injuries reported among passengers or crew members.
The incidents come as the global tourism industry navigates a challenging year marked by tensions in the Strait of Hormuz and the Iran war. Dave Goodger, managing director of Tourism Economics, shared his thoughts on the impact of such events on the industry.
"If it's a one off, that is something that we have seen that recovery getting quicker overtime. We've seen the reaction, the recovery from a whole series of different adverse events, whether it's terrorist attacks, whether it's geopolitical events, natural disasters, we have seen every single time travel has recovered and that recovery time has come quicker we've seen governments and travel tourism organizations and even all tourism stakeholders getting much better at handling this and getting a quicker response, getting that recovery back," he said.
