Bahraini authorities have been accused of heavy-handedness in handling pro-democracy protesters.

According to medics at Salmania hospital in the capital Manama, the security forces surrounded the hospital and disallowed people, including health workers and ambulance staff, to enter or leave the facility.

The hospital staff have told Al Jazeera that doctors and nurses were beaten up and that many doctors were still under arrest.

Many patients were allegedly also attacked by the military.
