(Reuters) – The United States’ war in Iran has cost $37.5 billion so far, U.S. Defense Secretary Pete Hegseth said on Tuesday, an increase of nearly $8 billion since ​the last public estimate.

Hegseth told lawmakers at a hearing in Washington that they included certain aspects of the war as well as anticipated costs through September 30.

Hegseth also told lawmakers ​that military training would need to be curtailed without an urgent funding boost.
