DUBAI — A bomb blast killed two Bahrain policemen and wounded six others Tuesday in an area often shaken by clashes between security forces and protesters, the Interior Ministry said.

The blast in Sitra island outside the capital Manama comes days after the Bahraini authorities announced they had foiled an attempt to smuggle weapons from Iran.

Police blocked routes leading to the island following the explosion — the latest in a series of blasts targeting police in villages, witnesses said.

“The explosives used in the terrorist incident are of the same quality of explosives seized recently while being smuggled from Iran,” the BNA state news agency reported.

The Interior Ministry described the blast as a “terror” attack. Footage of the aftermath of the explosion showed a shrapnel-riddled police bus with shattered windows.

Three policemen were killed in March 2014 in the kingdom’s deadliest attack against security forces.

They included an Emirati officer from the Saudi-dominated Gulf force that rolled into Bahrain in March 2011 to boost the security forces.

Bahrain, home to the US Fifth Fleet, and other Gulf kingdoms accuse Shiite Iran of inciting unrest across the Middle East.

Manama recalled its ambassador from Tehran over the weekend in protest against “hostile” comments by Iranian leaders.

On Sunday, Iranian Foreign Ministry spokeswoman Marzieh Afkham accused Bahrain of making “unfounded allegations” aimed at creating “tension in the region”.

Saudi Arabia, a strong backer of Bahrain, denounced the Iranian statements on Bahrain as “aggressive”.

Bahrain summoned Iran’s acting charge d’affaires earlier this month to protest after the Islamic republic’s supreme leader Ali Khamenei voiced support for “oppressed people” across the Middle East, including in Bahrain. — AFP
