The U.S. Justice Department announced charges Thursday against four foreign nationals after U.S. Navy SEALs interdicted a dhow vessel in the Arabian Sea that was allegedly transporting Iranian weapons to Houthi terrorists in Yemen. The mission, which was conducted in January, resulted in the death of two Navy SEALs.

In Thursday’s Justice Department press release, Attorney General Merrick Garland expressed condolences to the families and friends of the two Navy Seals who died during the interdiction mission on January 11 in the Arabian Sea.
