The execution of three Bahraini men found guilty of killing three policemen has sparked violent protests between the country's Shia majority and its Sunni rulers, AFP reported.
The three Shia prisoners were executed by firing squad six days after a court upheld their death sentences for a bomb attack in March 2014.
Bahrain, which has been ruled by the Sunni Al-Khalifa dynasty for over 200 years, has been rocked by sporadic protests since 2011 by its Shia population which has long complained of marginalization.
Photos of the protests shared online showed demonstrators blocking roads with burning tires, police retaliating with tear gas, and relatives of those executed weeping over their deaths.
International news agencies are not permitted to cover events independently in Bahrain.
The executions in Bahrain went ahead despite concerns that the prisoners' convictions were based on confessions obtained under torture, rights groups have said.
