The First Battle of Khorramshahr was a major battle in the Iran–Iraq War, beginning shortly after the Iraqi invasion of Iran in September 1980. Amidst the gruelling urban warfare in and around the city, Khorramshahr came to be referred to by the Iranians as Khuninshahr, as both sides had suffered heavy casualties in combat. It was the single largest urban battle of the Iran–Iraq war.
