US targets Iran's drone program with sanctions
The drones have also been supplied to Hezbollah, Hamas, and Yemen's Houthis, and have additionally been seen in Ethiopia, "where the escalating crisis threatens to destabilize the broader region," the Treasury said.
The sanctions singled out Brigadier General Saeed Aghajani, who leads the Revolutionary Guards' UAV Command.
The Treasury said that Aghajani was behind a 2019 drone attack on an oil refinery in Saudi Arabia as well as the July 29, 2021 attack on a commercial ship off the coast of Oman that saw two crewmen killed.
Also named to the sanctions blacklist were two companies, Kimia Part Sivan and Oje Parvaz Mado Nafar, which provide components for and help develop the armed UAVs of the Revolutionary Guards.
"Iran's proliferation of UAVs across the region threatens international peace and stability," Deputy Treasury Secretary Wally Adeyemo said in a statement.
"Treasury will continue to hold Iran accountable for its irresponsible and violent acts," he said.
The Pentagon has not identified the source of that incident, which did not cause any injuries, but says generally that Iran has provided drones for such attacks around the region.
"We have seen these kinds of attacks in the past from -- from Shia militia groups, which we know are backed and supported by Iran," Pentagon Spokesman John Kirby said on Monday.
That commitment came after a five-month gap which saw mounting warnings that international patience was wearing thin with Tehran.
Iranian foreign ministry spokesman Saeed Khatibzadeh said that the sanctions showed the "contradictory behavior" of President Joe Biden's administration.
"An administration that wants to return to nuclear negotiations is following the same methods of (former president Donald) Trump. By imposing sanctions, it is sending a message that does not inspire any confidence at all," he said.
