The Wall Street Journal reports that in December 2023, Austrian and Bosnian authorities arrested two separate groups of refugees from Syria and Afghanistan, seizing weapons such as Kalashnikov assault rifles and pistols.

On the detainees' mobile devices, authorities discovered photos of Jewish and Israeli objects in various European cities.

The investigation concluded that the suspected motivation for these terrorist activities was the ongoing conflict between Israel and Hamas.

Additionally, on March 11, Italian police announced the arrest of three Palestinians affiliated with the al-Aqsa Martyrs' Brigades, the military wing of Fatah. They were suspected of planning suicide attacks in various European cities.

The German Federal Office for the Protection of the Constitution has highlighted that the Gaza conflict has become a rallying point for radical Muslim groups. It warns that Jewish and Israeli targets are the primary focus of potential attacks.

According to intelligence sources, Hamas has spent years establishing a terrorist network in Europe, including organizing weapons caches. The conflict in Gaza has also provided opportunities for Hamas, Hezbollah, and other groups to recruit new supporters on the continent.
