TEHRAN, Iran An Iranian semi-official news agency reports attackers opened fire on a checkpoint in southeastern Iran, killing two policemen.
The report by Fars news agency said the attack happened before dawn Friday morning, near the town of Sarbaz in Sistan-Baluchistan province near the Pakistani border.
It says four terrorists dressed in local traditional clothing fled on motorbikes after the attack.
The province was hit by violence just a week ago, when a suicide attacker detonated explosives near a mosque, killing two people.
No one has claimed responsibility for either of the attacks.
The Sunni Muslim militant Jundallah group, which says it is fighting for the rights of Sunnis and the Baluch ethnic minority in mainly Shiite Muslim Iran, has been involved in sporadic bombings in the region in the past.
