Israel’s intelligence agency Mossad has alleged that Hamas has established a covert operational network across Europe capable of carrying out 'on-command' attacks. According to a Mossad statement, cooperation with European security agencies has led to the seizure of weapons caches, arrests of suspects, and the prevention of several planned assaults. Joint operations in countries such as Germany and Austria reportedly disrupted plots targeting Israeli and Jewish communities. A major breakthrough came in September when Austrian authorities discovered a weapons depot in Vienna linked to Mohammed Naim, son of senior Hamas political bureau member Bassem Naim. Mossad suggested that Hamas’s Qatar-based leadership may be quietly supporting these networks despite public denials. Investigators are also monitoring Hamas-linked individuals in Turkey, including one recently arrested in Germany. European intelligence agencies have intensified scrutiny of charities and religious organizations suspected of funding or spreading extremist ideology. Mossad claims Hamas has accelerated its foreign network expansion since the October 7 attacks, mirroring tactics used by Iran and its allies.
