Three men were arrested in Berlin on Wednesday on suspicion of procuring firearms for the Hamas militant group to carry out attacks against Israeli or Jewish targets in Germany, federal prosecutors said.

The suspects — identified under local privacy laws as German nationals Abed Al G. and Ahmad I., and Lebanese-born Wael F. M. — are accused of acting as “foreign operators” for Hamas, according to the prosecutors.

They face charges of membership in a foreign terrorist organization and preparing a serious act of violence endangering the state. Hamas is banned in Germany and is classified as a terrorist organization.

The three men allegedly procured firearms and ammunition for assassination attempts. The police seized several firearms, including an AK-47 assault rifle, pistols and ammunition, the prosecutors said.

Der Spiegel reported they had been arrested during a weapons delivery, with police also raiding apartments in Leipzig in eastern Germany and Oberhausen near the country’s western border.

An investigating judge will decide on Thursday whether to remand the suspects in custody.
