German police raid suspected Islamists in Berlin
It was unclear if they had made any arrests in the raids, which included one on a mosque association.
The police said they had been investigating a 51-year-old man from Morocco suspected of inciting others to join armed Islamist groups fighting Syrian President Bashar al-Assad. They are also investigating a 19-year old Macedonian believed to be in Syria already.
"There is no reason to believe that the suspects have prepared attacks in Germany," said Berlin police in a statement.
