Justice department claimed ownership of the ordnance on the grounds that they were being smuggled to Yemeni Houthi forces, breaching a UN embargo

The United States has supplied Ukraine with more than a million rounds of Iranian ammunition confiscated in the Gulf late last year.

The transfer of the ordnance followed a civil forfeiture case pursued by the justice department to gain ownership on the grounds that the bullets were seized as they were being smuggled to Yemeni Houthi forces in violation of a UN arms embargo.
