Iran live updates: Iran releases 'wrongfully detained' US citizen, Trump says

A U.S. aircraft fired at an oil tanker that "attempted to violate the U.S. blockade" on Iranian ports, U.S. Central Command said in a statement on Wednesday.

CENTCOM said the Curacao-flagged tanker M/T Belma was traveling in international waters toward Kharg Island when it ignored multiple warnings.

"A U.S. aircraft disabled the vessel after firing hellfire missiles into the ship’s smokestack. The ship is no longer transiting to Iran," CENTCOM said.

The U.S. resumed its naval blockade on vessels traveling to and from Iranian ports and coastal areas on Tuesday.

"During the first 24 hours of enforcement, CENTCOM has redirected two compliant commercial vessels and disabled one non-compliant vessel," the statement said.

President Donald Trump met with top officials in the Situation Room on Tuesday evening to discuss options for expanding military action against Iran, including possible targets that could be hit in the coming days, multiple sources told ABC News.

The White House declined to comment.

President Donald Trump said the U.S. might have to wipe out Iran's Islamic Revolutionary Guard Corps, saying it cannot be negotiated with. He claimed Iran called the U.S. on Wednesday asking to meet.

When asked whether he believes that he might have to take out the IRGC because he's concluded he cannot negotiate with them, Trump told Fox Business, "yeah," but added he has to "see what's happening."

The U.S. has launched another wave of airstrikes again, the second wave on Wednesday, U.S. Central Command said.

"At 3 p.m. ET, U.S. forces launched operations for a second wave of strikes today against Iran. The strikes are targeting Iranian military capabilities used to threaten vessels freely transiting through the Strait of Hormuz, an international waterway vital to global commerce. The U.S. military is holding Iran accountable at the Commander in Chief's direction," CENTCOM said in a statement.
