A local official confirmed on Thursday that the two officers were killed as they were returning from work in the mountainous areas of Mehrestan, a city located in the southernmost part of Sistan-Baluchestan province, Press TV reported.
Mehrestan is located 335 kilometers south of the provincial capital city, Zahedan.
Rashid Parsaei, governor of Mehrestan which is locally known as Zaboli, said unidentified gunmen fired at the two officers who were descending from Birak Mountain.
The two slain officers have been identified as Morteza Mohammad-Baqeri and Mohammad Mohammadi Soleimani. The pair worked in the telecommunications unit of IRGC in the neighboring Kerman province.
On Monday, terrorists killed eight border guards in a border area in the southeastern town of Negur before fleeing to Pakistan. The incident came after IRGC busted a major terror group in the region earlier in the day.
Sistan-Baluchestan province has witnessed similar attacks by terrorists who launch hit-and-run attacks and flee to neighboring Pakistan.
Iran has repeatedly criticized its eastern neighbor for failing to rein in the terrorists.
