US has struck three Iranian nuclear sites, Trump says, joining Israeli air campaign

The United States struck three sites in Iran early Sunday, inserting itself into Israel’s war aimed at destroying the country’s nuclear program in a risky gambit to weaken a longtime foe despite fears of a wider regional conflict.

Addressing the nation from the White House, President Donald Trump asserted that Iran’s key nuclear were “completely and fully obliterated.” There was no independent damage assessment.

It was not clear whether the U.S. would continue attacking Iran alongside its ally Israel, which has been engaged in a nine-day war with Iran. Trump acted without congressional authorization, and he warned that there would be additional strikes if Tehran retaliated against U.S. forces.
