Germany arrests three suspects for allegedly plotting ‘serious act of violence’

Three suspected Muslim extremists have been arrested in Germany on suspicion of preparing a "serious act of violence", with an assault rifle and knives also seized, authorities said Tuesday.

Police swooped Sunday on the homes of two German-Lebanese brothers aged 15 and 20 in the city of Mannheim, and a 22-year-old German-Turkish man from the Hochtaunus district of Hessen state.

The act that they were planning could have "endangered the state", local prosecutors and police said in a statement, without disclosing further details.

Germany has faced a string of attacks and plots by suspected extremists in recent years and has been on high alert since Hamas's October 7, 2023, attack on Israel sparked the war in the Gaza Strip.

The brothers detained in Mannheim, who had a "strong religious ideology and profound sympathy" for the Islamic State (IS) group, had made concrete preparations for an attack, authorities said.

The assault rifle, along with ammunition, was found during a search of the 22-year-old German-Turkish man's home, they said. Several knives, a balaclava as well as mobile phones were also turned up during searches.

But officials stressed that "at no point was there any concrete danger to the public". The suspects are in pre-trial detention.

Roman Poseck, Hessen state interior minister, praised law enforcement officials for making the arrests in "good time, before any acts could be carried out".

"At the same time, it is once again clear that the security situation is tense," Poseck added.

Germany has in recent times seen a series of allegedly terror-motivated knife attacks.

Three people were killed and eight wounded in a stabbing spree at a street festival in the western city of Solingen in August.

Police arrested a Syrian suspect over the attack that was claimed by IS.

In June, a policeman was killed in a knife attack in Mannheim, with an Afghan national held as the main suspect.

The fall of President Bashar al-Assad has stoked fears that IS could be revived in Syria.
