Syrian security police attacked Sunni Muslim protesters with batons as they exited a Damascus mosque on Friday, a witness said. Syria's minority Alawite-led government appeared to stepping up efforts to prevent pro-democracy demonstrations against their rule from spreading. "It was hard to know who was who because those 'Amn' (security) forces do not wear uniforms," the witness, a Westerner living near the Rifai mosque in the Kfar Souseh district of the Syrian capital, told Reuters.
