A policeman, who was injured in a bus explosion, died Saturday, Bahrain police said.
The policeman was among the two people who sustained injuries in a terror blast in Daih village, as anti-government protestors clashed with security forces in several parts of the country Friday to mark the third anniversary since protests broke out in February 2011.
"There was an explosion that damaged a bus carrying policemen in Daih," Xinhua quoted the interior ministry as saying in a statement.
"Two policemen were injured in a terrorist explosion," it said, adding that a policeman later died of his injuries.
The dead policeman has been identified as Waheed Al Balooshi.
Police said they arrested 26 rioters Friday and 29 Thursday who vandalised properties, illegally blocked roads to disrupt traffic and attacked police with firebombs in several parts of the kingdom.
"Some villages saw rioting, vandalism and the targeting of policemen. This required police to respond to these criminal acts with legal means," the ministry statement said.
