TEHRAN, July 23 (Xinhua) -- Four Iranian traffic policemen were killed on Sunday in a "terrorist attack" while they were patrolling on an intercity road in the southeastern province of Sistan and Baluchestan, the official news agency IRNA reported.
The "terrorists" fled the scene after the attack and investigations were underway, the provincial police were quoted as saying in a statement.
The provincial police also vowed a response to the "terrorists" strong enough to make them remorseful.
Bordering Afghanistan and Pakistan, the province has been the target of several terrorist attacks on both civilians and security forces over the past years.
In early July, two policemen and four "terrorists" were killed in an armed attack on a police station in the province, Iran's semi-official Tasnim news agency reported. ■
