First US casualties in Iran campaign raise stakes for Washington

The United States has confirmed its first military deaths in the ongoing operation against Iran, a development that shifts the tone of a campaign that, until now, had been measured largely in targets hit and political messaging rather than American losses.

US Central Command said three service members were killed and five others were “seriously wounded” during the operation.

“Several others sustained minor shrapnel injuries and concussions — and are in the process of being returned to duty. Major combat operations continue and our response effort is ongoing,” the statement said.

The military added that further details would be withheld for now, noting that “the situation is fluid, so out of respect for the families, we will withhold additional information, including the identities of our fallen warriors, until 24 hours after next of kin have been notified”.

The deaths came on the second day of a joint US-Israeli assault that has already redrawn the regional landscape, including the killing of Iran’s Supreme Leader Ayatollah Ali Khamenei. Tehran has answered with strikes on US-linked targets across the Middle East, signalling that the confrontation is moving into a more direct and potentially prolonged phase.

Iran’s Islamic Revolutionary Guard Corps said it fired four ballistic missiles at the USS Abraham Lincoln. A US official told Al Jazeera the attack caused no damage, and CENTCOM later said the carrier “continues to launch aircraft in support of CENTCOM’s relentless campaign to defend the American people by eliminating threats from the Iranian regime”.

At the same time, the scope of the American operation has become clearer. CENTCOM said more than 1,000 Iranian targets have been struck so far, including the headquarters of the Revolutionary Guards and Iranian navy submarines — an indication that the campaign is aimed not only at nuclear infrastructure but at the broader military architecture of the Iranian state.

In Washington, the political implications are already coming into focus. Reporting from the capital, Al Jazeera’s Alan Fisher noted that the loss of US personnel would “change a lot of things for the United States”.

“Donald Trump, of course, campaigned on the idea of being a president who wasn’t going to take the US into wars. He said that [former US Vice President] Kamala Harris, if she were elected, would start a fight with Iran that would lead to World War III,” Fisher said.

“There are many on the Democratic side who now want an emergency debate in Congress about this [the US operation in Iran] because what they want to know is, what are the administration’s plans? Where does this go? How long is this going to last?”

“And the big question, of course, is how many more service personnel will be put at risk,” he added.

The administration, fo its part, has continued to project confidence. Trump told Fox News that the operation was progressing without concern.

“I’m not worried about anything, and things are going well,” he said.

He also framed the strikes as pre-emptive, arguing that “Iran would have had a nuclear weapon within two weeks if it weren’t for our strikes against its nuclear facilities, and then this type of attack wouldn’t have been possible”.
