Operation Beit-ol-Moqaddas (Persian: عملیات بیتالمقدس; Operation Jerusalem), also known as the Operation Toward Beit-ol-Moqaddas (عملیات الی بیتالمقدس),[3] was an Iranian operation conducted during the Iran–Iraq War. The operation was a success, as it achieved its standing aim of liberating Khorramshahr and pushed Iraqi troops back to the border. This operation, coupled with Operation Tariq-ol-Qods, and Operation Fath-ol-Mobin, succeeded in evicting Iraqi troops from southern Iran and gave Iran the momentum.
