At least 11 planes from cities, including Dublin, Madrid, and Warsaw, were diverted or grounded over bomb threats that have been determined to be unfounded.

Multiple flights in Europe have been targeted by bomb threats, causing emergency landings and military escorts.

The bomb threats involved two passenger planes bound for Warsaw, a Ryanair flight from London to Spain, two flights to Rome and a flight traveling from Israel to the Bulgarian capital, Sofia. No explosives were found.
