“Through complex covert procurement networks, Iran seeks to supply rogue actors around the world with weapons systems that fuel conflict and risk countless civilian lives,” Under Secretary of the Treasury for Terrorism and Financial Intelligence Brian Nelson said in a statement.

“Through complex covert procurement networks, Iran seeks to supply rogue actors around the world with weapons systems that fuel conflict and risk countless civilian lives.”

The sanctions are the latest that the Biden administration has imposed on Iran’s procurement networks since October when it hit those supporting Tehran’s missile and drone programs.

The Middle Eastern country has been accused of selling drones to Russia and which evidence has been uncovered that Kremlin has used them in the Ukraine war.

However, the United States has more recently been vigorously targeting those facilitating Tehran’s proxy militias, which have become embolden amid Israel’s war against Hamas.

In particular, the Biden administration has been targeting the Houthi rebels of Yemen, who have been attacking shipping vessels as well as U.S. and British warships transiting the Red Sea.

The sanctions, officials have said, are part of an effort to degrade the ability of Iran and its proxies to make war.

“The United Stats is committed to using all available tools to expose and disrupt the networks supporting Iran’s reckless proliferation of weapons that destabilizes the Middle East and enables Russia’s continued aggression against Ukraine,” State Department spokesman Matthew Miller said Wednesday in a statement.
