There have been more violent clashes between protesters and the authorities in countries across the Middle East - inspired by successful uprisings in Tunisia and Egypt.
In Bahrain, the security forces opened fire on anti-government protesters who'd gathered in the capital Manama.
The demonstrators are calling for political reform and the removal of the royal family which has ruled the tiny island kingdom for 200 years.
