Bomb threats disrupt flights across Europe, no explosive devices found

A series of bomb threats against passenger flights across Europe has prompted emergency searches, briefly shut down an airport outside the Polish capital, Warsaw, and led the Italian Air Force to escort a Ryanair plane into Rome. At least seven flights and an Israel-bound cruise ship were targeted, according to officials. All of the planes landed safely, and searches found no explosives. The airlines affected included Ryanair, Wizz Air, Scandinavian Airlines and the Polish carrier LOT. Ryanair, the Irish budget carrier, appeared to be the hardest hit, with four of its flights to different destinations being targeted. No one claimed responsibility, and officials did not attribute blame.
