Greek special forces arrested a 37-year-old man working as an electrician at a luxury hotel on the island of Crete, accusing him of planning a terror attack on an Israeli cruise ship, part of what German prosecutors have called a broader Hamas weapons network stretching across Europe.
The suspect, identified only as Motasem, is an Egyptian man of Palestinian origin who had been living quietly in the Greek resort town of Agios Nikolaos when special forces raided his location in early June. Police found chemicals, a precision scale, and specialist bomb-making equipment in his apartment in Athens, the Daily Mail reported, citing an investigation by the Swiss newspaper Neue Zürcher Zeitung.
Investigators believe Motasem was targeting an Israeli cruise ship that regularly calls at Greek ports. He had reportedly been stopped by police alongside four other Palestinians during one of the ship's previous visits roughly a year earlier, and released without arrest.
That missed opportunity now looks like a significant failure. Motasem allegedly used the intervening months to travel to Malaysia in 2025, routing through Zurich, Qatar, and Indonesia, to learn how to manufacture explosives. A second, unnamed Palestinian reportedly made the same trip.
The arrest in Crete did not happen in isolation. Weeks before Greek forces moved on Motasem, Cypriot police arrested two Palestinians near the coastal city of Larnaca who were in contact with the suspect. Intelligence from that Cypriot operation led Greek authorities to Motasem.
The broader picture is far more alarming. German Federal Prosecutor General Jens Rommel believes members of the network were planning attacks on Jewish or Israeli institutions across Europe. German prosecutors described the alleged plot as a "second October 7th in Europe", a reference to Hamas' 2023 massacre in Israel, and said preparations had advanced to the point where a specific date had been chosen: the second anniversary of that attack, in October 2025.
German investigators recovered a pre-recorded claim of responsibility during their probe, a detail that suggests the plotters expected to carry out the attack and wanted the world to know who was behind it.
Since October of last year, German authorities have arrested nine men connected to the alleged network. Operations linked to those arrests touched Berlin-Brandenburg Airport, Larnaca Airport, London, Vienna, Berlin, and Copenhagen, a geographic footprint that spans half a dozen countries.
The arms pipeline allegedly ran through Scandinavia, Germany, and Austria. During the summer of 2025, roughly five Glock pistols were transported from Denmark to Vienna by way of Berlin. In total, investigators say the network smuggled at least 13 pistols, one AK-47 assault rifle, and more than 900 rounds of ammunition through those routes.
Austrian authorities uncovered a weapons cache in Vienna. Bulgarian police recovered a suitcase containing weapons and ammunition hidden in woodland near the city of Plovdiv in December 2023, after German investigators traced photographs found on the mobile phone of a Lebanese national named Ibrahim el-Rassatmi.
El-Rassatmi had allegedly been instructed by Lebanese Hamas as early as April 2019 to establish weapons depots, years before the October 7 attacks. Investigators suspect additional cache sites near the German-Polish border, though those have not been confirmed.
The timeline matters. If German prosecutors are right, Hamas was pre-positioning arms across Europe well before its assault on Israel, building infrastructure for a campaign that went far beyond the Middle East.
In February 2023, members of a Hamas cell based in Berlin were allegedly ordered from Lebanon to transport weapons and prepare attacks against Jewish, Israeli, or American targets. Cell members conducted surveillance of the Israeli embassy in Berlin, the Ramstein U.S. military base in western Germany, and Tempelhofer Feld, a large public park in Berlin.
Members of the Berlin cell reportedly traveled to Lebanon to meet Khalil al-Kharraz, a senior commander in Hamas' Qassam Brigades, the group's military wing. Al-Kharraz was later killed by the Israeli military in 2023. Security services identified several members of the Berlin cell in footage from his funeral.
Beirut served as a strategic hub. The Lebanese capital houses many Hamas officials and has direct air links to Larnaca, Cyprus, the same city where the two Palestinians connected to Motasem were arrested.
Hamas denied any connection to the men arrested across Europe, calling the accusations an attempt to "tarnish the movement's reputation." The organization insisted that its "struggle against the Zionist occupation" is limited exclusively to Palestine.
Hans-Jakob Schindler, a terrorism expert with the Counter Extremism Project, dismissed that claim.
"The personnel links to the Hamas leadership are too close."
Schindler said terrorist organizations seek publicity to demonstrate their continued relevance. He suggested that an attack in a European city or on a cruise ship in the Mediterranean would generate global attention while placing political pressure on countries viewed as supporters of Israel.
He also warned that Hamas' weakening military position in the Middle East could make attacks abroad more likely, not less.
"Hamas' weakness is not a good sign for Europe in itself."
Agios Nikolaos, the small Cretan resort where Motasem worked as a hotel electrician, had already seen tensions over Israeli cruise ship visits. Hundreds demonstrated against the arrival of Israeli cruise passengers in the town. Motasem blended into that environment, employed at a luxury hotel, living in a tourist destination, drawing no apparent alarm until Cypriot intelligence flagged his contacts.
He had previously lived in Germany for an extended period, a detail that connects him to the country where the largest number of arrests have occurred. How he moved between countries, obtained employment, and avoided detection for so long remain open questions.
So does the question of formal charges. It remains unclear what specific criminal counts, if any, have been filed against Motasem in Greece or against the two Palestinians arrested in Cyprus.
A man stopped by police and let go. A bomb lab in an Athens apartment. Weapons stashed in forests from Bulgaria to Denmark. A pre-recorded claim of responsibility. European authorities say they disrupted this network before it struck, but the infrastructure Hamas allegedly built over seven years across half a continent should keep every Western government awake at night.
