Violent skirmishes between young men and the security forces marred an attempt to mark the first anniversary of the failed pro-democracy uprising in Bahrain.
Clashes took place mainly on the outskirts of the capital city Manama, and the police presence was increased in surrounding villages.
Tensions also ran high at the site of the Pearl Roundabout – a previous focal point for a pro-democracy movement that was suppressed with the help of Saudi troops. The Shi’ite Muslim majority are unhappy with the rule of the Sunni royal family.
With uprisings gripping other Arab countries, pro-democracy protesters started calling for reforms last February, focusing their demonstrations at the now-demolished Pearl Roundabout.
By March, authorities started to crack down on the protesters, with the help of Saudi armed forces who had initially come to Bahrain to protect oil and gas facilities.
Many were arrested, including some opposition activists who are now serving sentences of life in prison.
