Italian police arrested a 22-year-old suspected neo-Nazi extremist accused of planning terrorist attacks against a synagogue in Milan and a nearby mosque. Investigators say the suspect had researched explosives, weapons modifications and methods of carrying out the attacks.

Authorities discovered Nazi propaganda, Holocaust-denial material and extremist writings on his electronic devices, along with evidence of preparations for explosives. Police believe he intended to carry out the attacks alone. The suspect remains under investigation on terrorism-related charges.
