Two Bahraini policemen were killed and six others wounded on Tuesday in a suspected terror bomb attack in south of capital Manama.

The Interior Ministry, in a statement, said the bomb blast took place in Shiite-dominated village of Sitra, south of Bahraini capital.

"Two on-duty policemen were martyred and a third severely injured when a terror bomb exploded in the Sitra area," the Ministry of Interior (MOI) said on its Twitter account, according to Bahrain News Agency. It further added that five more police personnel had moderate injuries.

"A bus carrying policemen on Tuesday at the end of their shift at the Sitra police station was attacked by a group of terrorists, who remotely-detonated a bomb planted there," police security chief Maj-Gen Tariq Al-Hassan said in a statement. An investigation was launched to identify and bring the offenders to justice, he added.

The Bahraini government claimed the explosives used in bombing were similar to those recently seized by authorities after allegedly being smuggled in from Iran, reported Reuters. "Early information suggests that the explosives used in today's terrorist attack are of the same type that were recently intercepted coming from Iran," the state news agency BNA said.

The Gulf Kingdom recalled its ambassador to Iran last week after it had foiled an explosives smuggling plot by two Bahrainis with ties to Iran, reported Al Arabiya.

Bahrain, a Shiite majority nation ruled by a Sunni monarch, has long accused Iran of interfering in its internal matter by supporting opposition groups and stirring up unrest among the Shiite majority.

Bahrain's largest Shia opposition group, Al Wefaq, condemned the attack saying that such acts are alien to the wide peaceful popular movement which is demanding a democratic transition in Bahrain, according to Al Jazeera.
