WASHINGTON, Feb 28 - U.S. President Donald Trump said on Saturday that the United States has launched what he described as "major combat operations" in Iran, and cautioned that American service members could be wounded or killed.

Speaking in a video circulated on Truth Social, the president said the strikes were focused on eliminating Iranian missiles and "annihilating its navy." He framed the action as forward-looking: "We’re doing this for the future, and it is a noble mission."

Trump acknowledged the human cost of conflict, saying: "The lives of courageous American heroes may be lost and we may have casualties that often happens in war, but we’re doing this, not for now. We’re doing this for the future, and it is a noble mission."

The president addressed members of the Islamic Revolutionary Guard, urging them to lay down their weapons and offering them immunity if they complied. He contrasted that option with what he called "certain death" for those who did not surrender.

Washington and Tehran held a series of talks in recent weeks concerning Iran’s nuclear ambitions, the president said, with the latest session occurring on Thursday and ending without a deal. "Iran refused, just as it has for decades and decades. They rejected every opportunity to renounce their nuclear ambitions, and we can’t take it anymore," Trump said.
