TEHRAN: A grenade attack and gun battle in Iran's southeast near Pakistan left four assailants and two Iranian policemen dead on Saturday, reports AFP.
It was the latest violence in Sistan-Baluchistan province, where unrest has involved drug smuggling gangs, rebels from the Baluchi minority and Sunni Muslim extremist groups. There was no immediate indication of who carried out the attack.
The attackers used grenades to blast open the gates of the police station, and an exchange of fire occurred, said Marhamati.
Two policemen were killed in the ensuing clash, according to Tasnim news agency, which quoted Sistan-Baluchistan Police Chief Doustali Jalilian.
All four terrorists involved in the attack were killed, according to Iran's official news agency IRNA, quoting a branch of the Iranian Revolutionary Guard Corps which commands southeast Iran.
Sistan-Baluchistan is one of Iran's poorest provinces. It is home to the Baluchi minority who adhere to Sunni Islam rather than the Shiite branch predominant in Iran.
In May, five Iranian border guards were killed during clashes with an armed group in Saravan, southeast of Zahedan, in one of the province's deadliest attacks in months.
Zahedan was also the scene of protests that flared in September, with dozens of deaths, over the alleged rape of a teenage girl by a police officer.
In late May, IRNA quoted a police official, Qassem Rezaee, as saying Taliban forces had shot at an Iranian police station in Sistan-Baluchistan, a drought-parched region which also borders Afghanistan. The two countries have been arguing over water rights.
Iranian police did not give details of casualties in that incident but local news agency Mehr reported one Iranian border guard had been killed. Afghanistan's ruling Taliban said one person was killed on each side.
