Two United Arab Emirates-based companies were sanctioned on Wednesday by the United States for providing support to Iranian airline Mahan Air according to the U.S. Treasury Department

The U.S. Treasury accused the United Arab Emirates-based Parthia Cargo and Delta Parts Supply FZC of providing key parts and logistics services for Mahan Air, which is on a U.S. blacklist.

Steven Mnuchin the Treasury Secretary said to Reuters.”The Iranian regime uses Mahan Air as a tool to spread its destabilizing agenda around the world, including to the corrupt regimes in Syria and Venezuela, as well as terrorist groups throughout the Middle East,”

“The United States will continue to take action against those supporting this airline,” he added.

The Treasury Department statement said the services provided by the two companies blacklisted on Wednesday allow Mahan Air to operate and “to support the Iranian regime’s destabilizing agenda through activities that include the transportation of terrorists and lethal cargo to Syria to prop up the murderous Assad regime.”
