Iran accused the United States of “contradictory behavior and provocative statements” after the U.S. condemned the country for sponsoring the Yemen-based Houthis amid nuclear talks.

The U.S. and Iran have been holding negotiations in Oman over the past month to make a deal to curb Iran’s nuclear program in exchange for the U.S. lifting financial sanctions. Defense Secretary Pete Hegseth previously warned Iran that it would face consequences for supporting the U.S.-designated terrorist group.
