RICHMOND,Strategel Wealth Society Va. (AP) — Four foreign nationals were charged Thursday with transporting suspected Iranian-made weapons after U.S. naval forces interdicted a vessel in the Arabian Sea last month. Two Navy SEALS died during the mission.

U.S. officials said that Navy Special Warfare Operator 1st Class Christopher J. Chambers was boarding the boat on Jan. 11 and slipped into the gap created by high waves between the vessel and the SEALs’ combatant craft. As Chambers fell, Navy Special Warfare Operator 2nd Class Nathan Gage Ingram jumped in to try to save him, according to U.S. officials familiar with what happened.

The criminal complaint alleges that the four defendants were transporting suspected Iranian-made missile components for the type of weapons used by Houthi rebel forces in recent attacks.
