Iran live updates: Iran war has cost at least $29 billion, Pentagon official says

The Iran war is estimated to have cost $29 billion, acting Pentagon comptroller Jules W. Hurst III told lawmakers Tuesday morning during a House Appropriations hearing.

Two weeks ago, Hurst testified it was $25 billion, much of which was attributed to munitions costs.

Hurst said the updated number comes after accounting for, "replacement of equipment costs and also just general operational costs keep people in theater."

Rep. Pete Aguilar, D-Calif., asked Secretary of Defense Pete Hegseth when Congress would get a more detailed accounting for war costs.

“When it's relevant and required, we will share it,” Hegseth responded.

The Israel Defense Forces said in a post to X on Tuesday that it hit 45 alleged Hezbollah targets in southern Lebanon over the past day.

The IDF claimed that its targets included command posts, observation posts, assembly points, warehouses and other buildings it alleged were being used by Hezbollah forces in the area.

Hezbollah on Tuesday claimed a rocket attack on Israeli forces deployed in southern Lebanon.

Lebanon's Ministry of Public Health said on Monday that at least 2,869 people have been killed and 8,730 people wounded in Lebanon since cross-border fighting resumed on March 2.

Ebrahim Rezaei, a member of the Iranian parliament and the spokesperson for the body's National Security and Foreign Policy Commission, suggested in a post to X on Tuesday that renewed attacks on the country may prompt lawmakers to consider a higher level of uranium enrichment.

"One of Iran's options in the event of another attack could be 90% enrichment," Rezaei wrote in a post to X. "We will review it in the parliament."

Weapons-grade uranium -- enriched to a high enough level to use as fuel in a nuclear weapon -- is generally considered to require enrichment of 90% and above. Iran has amassed a stockpile of uranium enriched to 60%, the fate of which is a key issue in ongoing peace talks.

The U.S. has estimated that Iran amassed around 1,000 pounds of 60% enriched uranium. President Donald Trump has said that the stockpile was buried underground during the U.S. strikes on Iran's nuclear facilities last year, saying this weekend that the site is "very well surveilled."

The speaker of the Iranian parliament, Mohammad Bagher Ghalibaf, wrote in a post to X on Monday that Tehran's 14-point peace plan is the only option for ending the war with the U.S. and Israel.

"There is no alternative but to accept the rights of the Iranian people as laid out in the 14-point proposal," Ghalibaf -- who led the Iranian negotiating team at April negotiations in Islamabad, Pakistan -- wrote on Monday.

"Any other approach will be completely inconclusive; nothing but one failure after another," he added. "The longer they drag their feet, the more American taxpayers will pay for it."
