The Zagreb rocket attacks were a series of two artillery attacks conducted by Serb armed forces that fired ground-to-ground missiles on the Croatian capital of Zagreb during the Croatian War of Independence. The attack killed seven and wounded over 200 Croatian civilians and was carried out on 2 May and 3 May 1995 as retaliation for the Croatian army's offensive in Operation Flash. The rocket attacks deliberately targeted civilian locations. Zagreb was the largest of several cities hit by the attack. It was the only instance in the entire war in Croatia that cluster bombs were used in combat.
