Operation Karbala-7 (Arabic: عملیات كربلاء ۷, Persian: عملیات کربلای ۷) was an Iranian offensive in Haj Omran during the Iran–Iraq War to prevent Iraq from rapidly transferring units to its defense lines at Basra after Iran had launched the failed Operation Karbala-5 to capture the city of Basra.[1][2] This was a failed Iranian attempt to reoccupy the summit of Kurda Mand Mountain.[3] There was an additional Iranian attack after this with the size of an infantry brigade on the night of 11–12 March, but this failed and suffered heavy losses.[3]
