Iran live updates: Nearly 400 US service members wounded in war, official says

As of Tuesday, 399 service members have been wounded in the war with Iran, according to a U.S. official.

The number has risen slightly since the ceasefire. That can be attributed to delayed reporting of traumatic brain injuries, as symptoms for those wounds can sometimes take a few days to manifest, according to the official.

Three service members are considered "seriously wounded," though it's unclear if those troops are the same who have been included in previous counts.

In total, 354 service members have been returned to duty.

The Treasury Department confirmed Tuesday that it would not renew the short-term authorization license waiving U.S. sanctions on Iranian oil already at sea. The sanctions will go back into effect on Sunday at 12:01 a.m. ET.

In a post on social media, the Treasury Department said that it was "moving aggressively with Economic Fury" to apply pressure to Iran and put financial institutions "on notice" that the department is prepared to implement secondary sanctions against foreign financial institutions doing business with Iran.

The sanctions were temporarily lifted as part of the administration's larger effort to increase supply and help drive global oil prices down. The U.S. also provided a waiver for Russian oil at sea to be temporarily unsanctioned amid the war. That license expired on April 11.

In the first 24 hours of the U.S. naval blockade in the Strait of Hormuz, no ships have made it through and six merchant vessels were directed to turn around, according to U.S. Central Command.

More than 10,000 U.S. sailors, marines, and airmen, along with over a dozen warships and dozens of aircraft, are executing the blockade against vessels entering or leaving Iranian ports and coastal areas, according to CENTCOM.

"U.S. forces are supporting freedom of navigation for vessels transiting the Strait of Hormuz to and from non-Iranian ports," CENTCOM said.

A new poll from Ipsos found that half (51%) of Americans say the decision to take military action in Iran has not been worth it. Another 24% say it has been worth it and 22% are unsure.

The poll found that 54% say the military action the U.S. has taken in Iran has had a mostly negative impact on their personal financial situation, while 29% say it has not had an impact.

On long-term U.S. security, the poll found that 41% of Americans think it will get worse due to the military action in Iran, 26% think it will improve, and 29% say it will not have an impact either way.

The poll, conducted from April 10 to 12, found that 60% of Americans disapprove of the U.S. military strikes against Iran and 35% approve -- little changed from when Ipsos last asked earlier this month and throughout March.
