TEHRAN: Two policemen were killed Saturday in Iran’s restive southeast near Pakistan, Iranian media said, in an attack claimed by jihadists that left four assailants dead.

The grenade attack and ensuing firefight at a police station was the latest violence to hit the Sistan-Baluchistan province, where unrest has involved drug smuggling gangs, rebels from the Baluchi minority, and Sunni Muslim extremist groups.

Also on Saturday, the Islamic republic’s judiciary said two men were hanged in public over a deadly shooting last year at a revered shrine in the southern city of Shiraz.

In Zahedan, the Sistan-Baluchistan provincial capital, “four unidentified armed individuals attacked and entered police station Number 16,” state broadcaster IRIB reported, citing the province’s deputy head of security Alireza Marhamati.

The attackers used grenades to blast open the gates of the police station, and an exchange of fire occurred, said Marhamati.
