Iran live updates: White House calls on other nations to secure Strait of Hormuz

Since the start of the war with Iran, 140 U.S. service members have been wounded, but a majority of the injuries have been minor, according to the Pentagon.

"Since the start of Operation Epic Fury, approximately 140 U.S. service members have been wounded over 10 days of sustained attacks," Chief Pentagon Spokesman Sean Parnell said in a statement on Tuesday. "The vast majority of these injuries have been minor, and 108 service members have already returned to duty. Eight service members remain listed as severely injured and are receiving the highest level of medical care."

The State Department says it is now aware of more than 40,000 American citizens who have returned to the U.S. since Feb. 28 and that its 24/7 task force has helped more than 27,000 Americans abroad.

The department's figure on charter flights stands at "over two dozen," which have "safely evacuated thousands." It says these operations are continuing for the time being even though demand is lessening and flights are operating at a 40% capacity.

Russian officials denied in a phone call with President Donald Trump on Monday that they are sharing intelligence on U.S. military assets with Iran, U.S. special envoy Steve Witkoff said.

"We can take them at their word," Witkoff said Tuesday in an interview with CNBC. "That's a better question for the intel people, but let's hope that they're not sharing."

Trump spoke with Russian President Vladimir Putin on Monday for about an hour. Witkoff also indicated during the interview that Trump is still open to dialogue with Iran.

"I think the president is always willing to talk, but the question is whether it would be productive or not," Witkoff said. "Do they actually want to make have a diplomatic solution here? And so far the evidence suggests no."

A new Ipsos poll found that 43% of Americans disapprove of the U.S. strikes on Iran, while 29% approve of them. Another 26% are unsure.

The polling, which ran from March 6 to 9, found that 64% say that President Donald Trump has not explained the objectives of the war clearly.

As a result of the U.S. military action in Iran, 67% think gas prices will get worse over the next year, including 85% of Democrats, 73% of independents and 44% of Republicans, the polling found. Nearly half of the respondents think the conflict will have a mostly negative impact on their own personal financial situation.

Americans are also more likely to think U.S. military involvement in Iran will go on for an "extended period of time," 60%, rather than "end pretty quickly in a matter of weeks," 36%.
