Protesters, police clash in Bahrain ABU DHABI (Reuters) - Around one hundred anti-government protesters threw stones and petrol bombs as riot police tried to disperse them with tear gas and stun grenades in Bahrain on Friday, witnesses said, after an earlier demonstration attended by thousands passed peacefully. At least two protesters were injured in the clashes, the witnesses said, which took place after a march near the capital Manama, which had been called for by main opposition bloc al-Wefaq and was authorized by the Bahraini authorities.
