Israel struck military sites in Iran early on Saturday, saying it was retaliating against Tehran's strikes on Israel this month, the latest attack in the escalating conflict between the heavily armed rivals.
Hours later the Israeli military said its strikes had been completed and its objectives achieved, but a semi-official Iranian news agency vowed a "proportional reaction" to Israeli moves against Tehran.
Iranian media reported multiple explosions over several hours in the capital and at nearby military bases, starting shortly after 2am (2230 GMT on Friday).
Before dawn, Israel's public broadcaster said three waves of strikes had been completed and that the operation was over.
Iran said its air defence system successfully countered Israel's attacks on military targets in the provinces of Tehran, Khuzestan and Ilam with "limited damage" to some locations.

The Middle East has been on edge awaiting Israel's retaliation for a ballistic-missile barrage carried out by Iran on Oct. 1, in which around 200 missiles were fired at Israel and one person was killed in the West Bank.
Tensions between arch rivals Israel and Iran have escalated since Hamas, the Iran-backed Palestinian group based in Gaza, attacked Israel on Oct. 7, 2023. Hamas has been supported by Lebanon-based Hezbollah fighters, also backed by Iran.
Fears that Iran and the U.S. would be drawn into a regional war have risen with Israel's intensifying assault on Hezbollah since last month, including airstrikes on the Lebanese capital Beirut and a ground operation, as well as its year-old war in Gaza.
"In response to months of continuous attacks from the regime in Iran against the State of Israel - right now the Israel Defense Forces is conducting precise strikes on military targets in Iran," Israel's military said in a statement announcing the attack.
