The U.S. levied economic sanctions on an accused Iranian money launderer along with two Afghans and two Russians for helping Houthi militants in Yemen.

The U.S. Treasury Department Wednesday sanctioned an alleged network of Houthi financial and procurement operatives it said has procured tens of millions of dollars worth of weapons and other goods from Russia.

The sanctioned network helped the Houthis acquire "tens of millions of dollars' worth of commodities from Russia, including weapons and sensitive goods, as well as stolen Ukrainian grain," according to the Treasury.
