Berlin - German Police on Tuesday raided a mosque in Berlin whose preacher was suspected of transferring funds to an Islamist fighter in Syria for the purpose of carrying out "terrorist criminal acts", prosecutors said.

Officers searched As-Sahaba mosque in Berlin's northern district of Wedding, where 45-year-old Ahmad A. - known to his followers as Abul Baraa - preaches, the General Prosecutor's Office said.

There was no immediate comment from the cleric or any lawyer representing him.
