Iran US War Latest Updates: Iran's military has launched its first missile attack targeting Israel since a fragile ceasefire took effect in early April, raising the possibility of a return to heavy fighting and complicating mediation efforts to reach a potential deal to end the US-Israeli war with Iran. The attack came a day after Tehran warned of retaliation after Israel struck Beirut's southern suburbs without warning on Sunday in defiance of Washington's request days ago to stand down. Iran confirmed the bombardment and closed its western airspace to brace for a possible response. Neighbouring Iraq and Syria have also closed their airspaces, bracing for possible Israeli aggression. "Should these acts of aggression be repeated, the responses will be broader in scope and will encompass all American and Zionist targets throughout the region," Iran's Revolutionary Guard said in a statement that referenced attacks in Lebanon and on Iran's coast and vessels around the Strait of Hormuz.
