Manama streets deserted in clampdown in Bahrain

Security forces with tanks have overrun a square in the centre of Bahrain's capital Manama where anti-government protesters have been camped for weeks.

At least three civilians were reportedly killed after police fired on mainly Shia protesters. Officials said three police also died.

Troops have taken over a hospital treating the wounded. Officials have imposed a curfew and banned protests.
