    Mateusz W. is to stand trial accused of planning a terrorist attack on a Christmas market

    A Polish student – 20-year-old Mateusz W. – is to stand trial accused of planning a terrorist attack on a Christmas market in Poland as an act of support for Islamic State. He was arrested in December 2025.

    He had been preparing a mass attack at a Christmas market, which he planned to carry out using explosive materials.

    According to the Internal Security Agency (ABW), the suspect had “intended to join a terrorist organisation affiliated with the so-called Islamic State and sought people who could help him carry out this plan”.

    After news of Mateusz W.’s detention emerged, KUL suspended his student status. The university’s spokesman, Wojciech Andrusiewicz, said that neither fellow students nor lecturers had noticed any unusual behaviour by the suspect.
