Bomb threats disrupt at least 15 flights across Europe, raising hybrid war fears

Planes forced into emergency landings or diversions two days after hoax alerts affected air travel

Bomb threats have caused diversions and emergency landings for at least 15 flights across Europe, renewing questions about a possibly coordinated effort to disrupt travel.

The series of warnings on Thursday morning affected flights between Italy, Ireland, the UK, Spain, Bulgaria, Romania, Poland, Finland, Austria, Denmark, Belgium, Portugal, Greece and Czechia.

On Tuesday seven planes across Europe were searched or diverted after malicious hoax bomb alerts. On Monday a flight from the UK to Bulgaria was diverted after a threat that was apparently without substance.
