The interception took place in international waters in the Gulf of Oman on Monday, US Central Command said. A team from the USS Chinook, a patrol coastal vessel, boarded the other ship along a route historically used to smuggle weapons from Iran to the Houthis in Yemen.

“The illegal flow of weapons from Iran through international waterways has a destabilizing effect on the region,” said Gen. Michael Erik Kurilla, the commander of US Central Command.
Yemen has been engulfed in a devastating civil war since 2015, which has plunged the Gulf country into what has long been identified by aid groups as one of the world’s worst humanitarian crises. Iran has supported the Houthis, a rebel group who overthrew the government at the start of the war, against a coalition led by Saudi Arabia and aided by US military support. The war between the two factions has brutalized the country, leading to widespread poverty and famine, and tens of thousands of civilian casualties.
Tensions between the US and Iran have increased in recent months due to the crackdowns on civil unrest throughout the country. Additional US sanctions on Iranian officials were announced just last week over their involvement in the production of drones being used by Russia in their war against Ukraine.
The US has intercepted other shipments of weapons and explosives before along similar routes.
In November, the Navy seized what it described as a “large quantity” of explosives from a fishing vessel in the Gulf of Oman. The shipment included 70 tons of ammonium perchlorate and 100 tons of urea fertilizer, which are used to make explosives and rocket fuel. US forces sunk the vessel after determining it was a hazard to navigation for commercial shipping.
