Polish officials have thwarted an alleged attack inspired by ISIS, aimed at a Christmas market, by charging a student with planning a large-scale bombing, as per local authorities.

This incident coincides with heightened security measures in Germany and the United Kingdom following a recent tragic event in Sydney, where a gunman killed 16 people at a Jewish Hanukkah gathering on Bondi Beach.

Authorities in Poland have identified 19-year-old Mateusz W. as the suspect, who was apprehended in late November at a residence in Lublin by the Internal Security Agency (ABW).

Jacek Dobrzyński, a spokesperson for the Minister’s Coordinator of Special Services, stated that the investigation suggests the young man was researching bomb-making techniques and intended to join a terrorist group to execute the attack.

“The aim of the act was not only to instill fear among the public but also to support the Islamic State,” Dobrzyński conveyed in a statement released on X.

“The purpose of the crime was to intimidate many people, as well as to support the Islamic State,” Dobrzyński said in a statement shared on X.

Items linked to Islam and digital storage devices were seized, and the suspect has been remanded for three months as the Szczecin branch of ABW continues its investigation.

At a news conference, Dobrzyński also referenced a June case in which three 19-year-olds were charged over alleged extremist plots, including a reported plan to attack a school in Olsztyn.

“You are familiar with this issue from Olsztyn; now we have another example of preparing an attack before Christmas,” he told reporters, according to GB News.

In Germany, police in Lower Bavaria also arrested five men on Dec. 12 on suspicion of preparing an attack on a Christmas market, according to reports.

“Sadly, as shown by the appalling attack on Sydney’s Jewish community during a Hanukkah event, we know they can also be a target for terrorist activity,” Deputy Assistant Commissioner Jon Savell said in a press release.

He cited large festive gatherings, religious services and Christmas markets as potential targets.

In the release posted Tuesday, he urged the British public to report anything that “doesn’t feel right” as part of the annual winter vigilance campaign.

Meanwhile, U.S. authorities say they separately disrupted a New Year’s Eve plot in Southern California.

Four alleged members of an extremist anti-capitalist, anti-government group suspected of rehearsing coordinated bombings against sites linked to two U.S. companies were arrested on Monday.
