President Donald Trump on Sunday said that the United States has bombed three nuclear sites in Iran, joining Israel's war against the US's major rival.
Mr Trump, who on Friday said he would take as long as two weeks to decide whether the US should enter the conflict on Israel's side, said the American planes "completed a very successful attack" on Fordow, Natanz, and Esfahan.
This is the first time since the Iranian Revolution in 1979 that the US has attacked facilities inside Iran.
"Iran's key nuclear enrichment facilities have been completely and totally obliterated. The strikes were a spectacular military success," he said in a televised Oval Office address.
