The move, the first time the U.S. has attacked Iran, is a major escalation of the conflict between Israel and Iran. U.S. involvement has divided Republicans, including Trump's closest allies.

WASHINGTON (AP) — President Donald Trump says Iran’s key nuclear sites were “completely and fully obliterated” by U.S. strikes. Trump made the comments at the White House Saturday night hours after announcing the U.S. military had carried out strikes against three key nuclear facilities in Iran.

President Donald Trump announced Saturday evening that US military forces had dropped bombs on three Iranian nuclear facilities, ending a weeklong deliberation period over joining Israel’s campaign against Tehran and thrusting the United States squarely into an escalating Middle East conflict.
