The US Department of Treasury announced new sanctions on Iran after accusing it of "lethal" arms delivery to Russia.

According to The Iran Project, the US Treasury on Tuesday imposed sanctions on 10 individuals, 6 entities and 4 ships in Iran and Russia under the pretext of sending missiles from Tehran to Moscow.

"Today, in response to Iran’s ongoing military support, including the recent delivery of ballistic missiles, to Russia for its war of aggression against Ukraine, the U.S. Department of the Treasury’s Office of Foreign Assets Control (OFAC) is designating ten individuals and six entities based in Iran and Russia and identifying four vessels as blocked property that are enabling Iran’s delivery of weapons components and weapons systems, including unmanned aerial vehicles (UAVs) and close-range ballistic missiles (CRBMs), to Russia," the Treasury said in a statement appeared on its website.

"Concurrent with this action, international partners are announcing measures which will not allow Iran Air to operate in their territory in the future and are pursuing further designations of Iran- and Russia-based individuals, entities, and vessels involved in the transfer of Iranian lethal aid to Russia. The Department of State is concurrently designating three entities, including Iran Air, and identifying five vessels as blocked property involved in the proliferation of Iranian weapons systems to Russia," the statement further read.

The sanctions came while Iran has always called for a political solution to the Ukraine war, categorically rejecting any allegations of arms supplies to Moscow.
