Polish authorities have foiled a suspected ISIS-inspired plot to attack a Christmas market, charging a student accused of preparing a mass-casualty bombing, according to officials.
The case comes as Germany and the U.K. also raised security measures around religious and cultural events in the wake of the Sydney shooting on Sunday where 16 people were shot dead at a Jewish Hanukkah party on Bondi Beach.
Polish authorities say the suspect, identified as Mateusz W., 19, was detained in late November at an apartment in Lublin by officers from the Internal Security Agency (ABW).
According to Jacek Dobrzyński, a spokesperson for the Minister’s Coordinator of Special Services, investigators believe the teen had been studying how to make explosives and intended to join a terrorist organization to help carry out the attack.

“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.
