Iran fired a salvo of ballistic missiles at Israel on Tuesday in retaliation for Israel's campaign against Tehran's Hezbollah allies in Lebanon.
Alarms sounded across Israel and explosions could be heard in Jerusalem and the Jordan River valley after Israelis piled into bomb shelters. Reporters on state television lay flat on the ground during live broadcasts.
Iran's Revolutionary Guards said Iran had launched tens of missiles at Israel, and that if Israel retaliated Tehran's response would be "more crushing and ruinous".
A senior Iranian official later told Reuters that the order to launch missiles at Israel was made by the country's Supreme Leader Ayatollah Ali Khamenei. Khamenei remains in a secure location, the senior official added.
The Israeli army said Israel's airspace was closed following the Iranian attack.
