The 10 defendants were found guilty of being behind ‘terrorist plots’, detonating explosives and resisting police, the kingdom's public prosecution said in a statement.
‘Four were sentenced to life in prison, while the remaining defendants were jailed between three to 15 years,’ it said.
The defendants were charged of detonating a roadside bomb when a police patrol passed in the village of Akr, south of Manama, in April 2014.
Three police vehicles were damaged in the attack, the prosecution statement said.
