Israeli police have arrested controversial Islamic activist Raed Salah on suspicion of incitement.
Sheikh Salah, the leader of the northern branch of the Islamic Movement in Israel, was detained in Jerusalem on Tuesday.
It is understood that he was on his way to give a press conference urging Palestinians to protest about the al-Aqsa Mosque when he was arrested by intelligence officers.
Israeli authorities claimed Sheikh Salah had accused Israel of trying to set fire to the mosque during a speech last week.
