Trump hailed the attack as a turning point, saying Iran must now agree to end the conflict following a “very successful” strike on three nuclear sites.

New satellite photos show the aftermath of the U.S. strike that dropped multiple 30,000-pound "bunker-buster" bombs on Iran's Fordo nuclear facility.
