Europe is Facing More Disruption. Hundreds of Schools Had to be Evacuated Over Fake Bomb Threats.

Hundreds of schools in the UK and Italy have been evacuated on Wednesday over fake bomb threats as disruptions across the continent continue.

Italian Education Minister Giuseppe Valditara told local TV that threats were sent by email and presumed to be hoaxes, but schools were evacuated nonetheless.

The messages arrived in the morning and were signed by "Mikhail Andropov, leader of the Vilayat of Misoginistan," Reuters detailed.

Authorities in Scotland and Northern Ireland also saw the messages as false, with Scottish police saying nothing suggested there was a credible risk to the public.

"Based on enquiries and information to date, police are treating this email, which originated from outside the UK, as a hoax," police said in a statement.

Different countries have been getting similar threats and facing cyberattacks over the past weeks, escalating concerns of hybrid warfare taking place in the continent.

The settings on equipment that keeps plasma frozen at three French blood banks were disrupted last week. Alarms gave staff time to intervene, and France's national blood service said no products or samples were compromised.

At a Stockholm supermarket that same day, the damage was already done by the time employees discovered the problem. A store manager said the freezers had reached 122 degrees Fahrenheit.

Those two incidents on November 2 opened a week in which suspected bomb hoaxes diverted passenger flights and security threats disrupted broadcasters. Authorities have yet to publicly identify who was behind the wave of incidents or establish whether they were connected.

In France, the hackers targeted a refrigeration contractor that served the national blood service, Euronews reported. Collection and distribution continued as usual. The incident showed how access through an outside supplier could threaten medical supplies, and how much depended on staff detecting and reversing the changes before the plasma warmed. France concluded that Iran was behind the attacks against freezers and vowed to respond.

"We rule nothing out and will take all measures, including those we may not disclose publicly, that we deem proportionate and necessary to deter any further attacks," Foreign Minister Jean-Noël Barrot told Franceinfo television. The goal is to deter actors "in Iran or elsewhere" from conducting a similar operation in the future. Paris also summoned the Iranian ambassador on Tuesday.

France was not the only country targeted. Eight European nations had to discard food after their refrigeration systems were tampered with. One Swedish supermarket reported that its refrigerator and freezer controls had been set to 50 degrees Celsius, or 122 degrees Fahrenheit, according to The Associated Press.
