Planes bound to European cities have been hit with bomb threats on Tuesday, forcing landings and shutdowns across the continent.

At least six flights received threats. Polish authorities conducted inspections of two planes hit by threats, not finding any explosives. However, operations were shut down before resuming around noon.

"The passengers were evacuated and the plane underwent security checks. Nothing was found," airport spokesman Adam Szablowski told French news agency AFP.

Other planes targeted were a Ryanair plane headed for Spain, two flights to Italy and one going from Israel to Bulgaria. No explosives were found in them either.

The threats come shortly after a wave of cyberattacks hit different European supermarkets, leading them to throw away refrigerated food as temperatures rose artificially.

Chains in Sweden, Belgium and Luxembourg claimed that several stores experienced such incidents. They include Coop and ICA in Sweden, and Spar and Shop & Go in Belgium.

"There has been a cyberattack and all our freezers reached 50 degrees (Celsius)," said Engla Ingwall, Sales manager at an ICA franchise in Stockholm when speaking to Reuters.

The attacks took place just a month after French supermarkets also experienced soaring temperatures in their freezers.

Hundreds of French supermarkets were targeted in a cyberattack that caused freezers to overheat and raised the temperatures on refrigeration units.

Some stores saw their fridges heat up to 122 degrees overnight.

"I strongly condemn the cyberattack targeting food products," European Commissioner for Agriculture and Food Christophe Hansen wrote at the time on X. "Food security requires more attention at all levels. Because the weaponization of food has become a reality."

The U.S. also saw a similar situation in August at a military base, with officials believing that mysterious freezer malfunctions resulted from malicious activity.

In late August, six on-base commissaries experienced problems with their freezers. In one case, the unit did not simply start working; rather, temperatures were raised overnight.

Fort Huachuca, Arizona, described what happened in a social media post on Facebook.

"It appears the outage has effected more than frozen food. Produce and additional reach-in coolers are also offline as well. Commissary employees are still pulling products from shelves. Please pay close attention to all signage," the post stated.

The post further stated that "ALL freezers went into defrost mode – ALL frozen food has spoiled. At this time, there are NO frozen food items for sale until further notice. We will continue to provide updates as available."
