The incident happened at a border post in the northwestern Iranian city of Sardasht at around 23:00 (local time) on June 5, 2018.
The victims were First Lieutenant Yousef Piraneh and Sergeant Major Mahboub Qorbani.
The two border guards were killed in clashes with 20 terrorists, whose plot was foiled thanks to the guards’ sacrifice.
The terrorists were finally forced to flee the country and enter the Iraqi territory.
