This is CNBC’s live coverage of the U.S.-Israel strikes in Iran.

The U.S. and Israel on Saturday began what President Donald Trump described as “major combat operations” in Iran, striking military and nuclear targets.

Trump said his objective for the attack “is to defend the American people by eliminating imminent threats from the Iranian regime,” Trump said in an eight-minute clip posted to his Truth Social account on Saturday. He dubbed the attack “Operation Epic Fury.” The move could cause a broader conflict in the region, as Iran has vowed a “crushing” response, Reuters reported.

The U.S. had assembled a massive fleet of fighter jets and warships in the region ahead of the attack in an effort to pressure Iran into a deal over its nuclear program.

Trump vowed to “destroy their missiles and raze their missile industry to the ground.” He also said U.S. forces would “annihilate their navy … and ensure that Iran does not obtain a nuclear weapon.” He called on Iranians to “take over” their government.
