German police have arrested a Lebanese national on suspicion of being a member of Hamas and planning attacks in Europe.

The man, named as Mohammad S, was stopped at Berlin's Brandenburg Airport after arriving from Beirut on Friday evening.

Federal prosecutors stated that in August 2025, he helped procure 300 rounds of ammunition and was involved in an alleged plot to attack Jewish and Israeli institutions.

He is due to be brought before a federal judge who will decide on a pretrial detention.

Hamas, which controls Gaza but has been severely weakened by Israeli operations in the territory, is considered a terrorist organization by the US, UK, Israel, and many other countries.

The militant Palestinian group carried out attacks on Israel in October 2023, resulting in around 1,200 deaths and more than 250 hostages taken.

Since then, it's reported that over 70,000 Palestinians have been killed due to Israeli military actions, according to Gaza's Hamas-run health ministry.

German authorities claim that Mohammad S colluded with Abed Al G, one of three alleged Hamas members arrested last October for planned attacks.

The trio was reportedly detained while meeting for a weapons handover in Berlin; two are German nationals, while one is from Lebanon.

At that time, police conducted searches in Leipzig and Oberhausen, as reported by Der Spiegel.

Additionally, in November, authorities arrested another suspected Hamas member, also a Lebanese national, near the Czech Republic border.
