Thousands of Syrian protesters marched in the streets of a Damascus suburb Friday, shouting and chanting against the government.

    In the mostly Sunni Muslim city of Horns, witnesses say protesters dispersed as security forces fired automatic rifles.
    In the flashpoint port city of Banias, scores of protesters marched towards the city center to demonstrate against the government, despite the presence of army troops. In a move to appease protesters, the government announced the release Friday of some prisoners arrested during recent sectarian strife.
    A video released by the opposition Sham TV showed dozens of protesters in Banias being beaten by what appeared to be Syrian secret police.
