Mossad and European Agencies Dismantle Alleged 'Hamas Octopus' Network Across Europe

A coordinated counterterrorism operation across multiple European countries has disrupted what Israeli officials describe as a substantial Hamas network preparing attacks on Israeli and Jewish civilians. The effort was led by Israel’s Mossad in close cooperation with several European intelligence and law-enforcement services.

Authorities describe an organized network

Israel’s Prime Minister’s Office, issuing a statement on behalf of the Mossad for Intelligence and Special Operations, said the disrupted cells were part of a broader campaign by Hamas leaders to build a terror infrastructure on the continent. Officials described the structure as a "Hamas Octopus," saying it included operational cells, weapons caches and logistical routes intended to be activated "on command."

"There are active cells across Europe right now, already on their way to targets, and the public — along with law-enforcement bodies in these countries — must be significantly more alert as this activity continues," said a senior Israeli intelligence official.

Key discoveries and links

One important discovery came in September in Vienna, when Austria’s security and intelligence service uncovered a weapons stash containing pistols and explosive materials. Israeli authorities tied the cache to Muhammad Naim, identified as the son of senior Hamas political bureau member Bassem Naim.

Investigators say they also linked the Vienna activity to events outside Europe after learning Muhammad Naim met his father in Qatar in September. Israeli officials contend the timing points to possible involvement by figures abroad in advancing the network’s operations, while acknowledging that public denials by senior movement leaders could reflect either denials of involvement or a loss of control over so-called "rogue operatives."

Probes extend to Turkey and Germany

The investigation expanded into Turkey, which Israeli officials characterized as a convenient area of activity for Hamas operatives. European services are examining plots tied to operatives moving through Turkish territory. In November, German authorities arrested Burhan al-Khatib after he travelled from Turkey; Israeli officials said that arrest likely followed operational activity on European soil.

Israeli sources allege that some direction and operational guidance have been carried out from inside Turkey, and they warned that Turkey’s hosting of Hamas elements is contributing to activity in Europe. Turkish authorities have different public positions on these issues; investigations and international cooperation are ongoing.

Broader response and ongoing work

Israeli officials say the multinational cooperation reflects a growing European recognition of the threat posed by Hamas-related activity beyond the Middle East. Authorities note recent steps by European governments to target alleged incitement, recruitment and fundraising networks, including charities and religious institutions believed to be exploited to raise funds and recruit operatives.

The Mossad says it continues to work with international partners to prevent attacks on Israeli, Jewish and other civilian targets. Israeli officials added that since the Oct. 7 attacks they have seen an acceleration in efforts to build infrastructure abroad and that intelligence services are working to thwart dozens of alleged plots worldwide. Investigations remain active and cross-border cooperation is continuing.
