The U.S. Navy reported that it has seized an arms shipment of thousands of Chinese and Russian assault weapons, machine guns, and sniper rifles hidden aboard a ship in the Arabian Sea. They were apparently bound for Yemen to support the country’s Houthi rebels.

The guided-missile cruiser USS Monterey intercepted a dhow, a traditional Arabian Sea sailing vessel, and discovered the cargo during a routine boarding in a two-day operation that began on May 6, according to the U.S. Fifth Fleet.

The Navy’s investigation team learned from interviewing the crew and assessing the weapons found, that the vessel came from Iran, said a Navy official who spoke on condition of anonymity. Iran continues to arm the Houthi rebels despite a UN embargo. In the past, Tehran has frequently denied that it has been supplying the rebels.

“The cache of weapons included dozens of advanced Russian-made anti-tank guided missiles, thousands of Chinese Type 56 assault rifles, and hundreds of PKM machine guns, sniper rifles, and rocket-propelled grenades launchers,” the Fifth Fleet said in its statement.

The U.S. Navy’s regular patrols in the region “disrupt the transport of illicit cargo that often funds terrorism and unlawful activity.” The Navy has seized other illicit arms shipments headed for Yemen in the past, enforcing the UN’s arms embargo on the embattled country.

The operation took 36 hours with the Monterey providing security for the boarding teams. “After all illicit cargo was removed, the dhow was assessed for seaworthiness and after questioning its crew was provided food and water before being released.”

Several other arms seizures have taken place during the Yemeni civil war.

Yemen Is One of the World’s Worst Humanitarian Crises

This latest arms seizure comes as the U.S. and the UN try to end a conflict that created one of the world’s worst humanitarian disasters.
