Operation Muslim Ibn Aqil (Persian: عملیات مسلم بن عقیل; also spelled Moslem ibn Aghil) was an operation during the Iran–Iraq War^[2] which was launched by the Islamic Revolutionary Guard Corps (IRGC) and the Iranian Army^[3] with the code of "Ya Abal-Fazl al-Abbas" on 1 October 1982.^[4][5]

The goal of the operation was to capture all heights which were overlooking the town of Mandali, Iraq. Another goal of the operation was to ensure the middle-front borders, secure the liberated Iranian territory, and expel Iraqi forces from the west of Sumar, Iran.^[6]

During the operation,^[7][8] Iranian forces were successful in the first stage; their progress rate reduced at the second stage, and eventually they were unable to consolidate their conquered positions.^[9]

In the operation which was done in two steps in a seven-day period,^[10] 150 km² of Iranian territory was liberated, and approximately 30 km² of Iraq was seized by Iranian forces. Meanwhile, as well as ensuring Sumar, the Iranians dominated the Giskeh heights, Kohneh-Rig and straits of Iran-Iraq border.^[6] The operation finally finished on 7 October 1982.^[11]
