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 presented before a federal judge who will determine his pretrial detention status.

Hamas, which controlled Gaza but has been significantly weakened by Israeli military operations, is identified as a terrorist organization by numerous countries, including the US, UK, and Israel.

The militant Palestinian group executed attacks on Israel in October 2023, resulting in the death of approximately 1,200 individuals and the abduction of over 250 people.

According to Gaza's Hamas-run health ministry, Israeli military actions have claimed over 70,000 Palestinian lives since those attacks.

German authorities have indicated that Mohammad S collaborated with Abed Al G, one of three individuals arrested last October for attempting to carry out attacks against Jewish and Israeli institutions.

The three were reportedly detained during a meeting for a weapons handover in Berlin, with two of those arrested being German nationals and another from Lebanon.

Police conducted searches in Leipzig and Oberhausen around the time of these arrests, as reported by Der Spiegel.

Additionally, in November, German authorities apprehended another suspected Hamas affiliate, also a Lebanese national, near the Czech Republic border.
