Photos of before and after Mersad Operation

The Mujahedeen worked with the Iraqi air force, armour, and chemical weapons to attack western Iran, advancing towards Kermanshah. With few Iranian troops in the field, the MEK advanced very rapidly, seizing and destroying the towns of Qasr-e Shirin, Sarpol-e Zahab, and Islamabad-e-Gharb, and pushing towards the provincial capital city of Kermanshah.
