Those designated under the action against Hezbollah include Iraqi national 'Ubayd al-Zaydi, who is allegedly linked to Iran's Revolutionary Guard. Lebanese nationals Muhammad Farhat, Yusuf Hashim, Adnan Hussein Kawtharani and Jawad Nasrallah were also designated.
The Treasury also imposed sanctions on the Al-Mujahidin Brigades, a militant group which operates in the Gaza Strip, West Bank and Egypt.
Four of the individuals — Zaydi, Farhat, Hashim and Kawtharani — were designated over their alleged role in coordinating the activities of Hezbollah in Iraq, the Treasury Department said in a statement.
"The US Department of the Treasury’s Office of Foreign Assets Control (OFAC) took action today to target four Hizballah-affiliated individuals who lead and coordinate the group’s operational, intelligence, and financial activities in Iraq," the statement said.
The Treasury said Zaydi has acted as a financial coordinator between the Qods Force and armed sectarian groups in Iraq on behalf of Qods Force Commander Qasem Soleimani, who the US has previously sanctioned.
"Hizballah is a terrorist proxy for the Iranian regime that seeks to undermine Iraqi sovereignty and destabilize the Middle East. We are targeting terror facilitators like Al-Zaydi who smuggle oil for Iran, raise funds for Hizballah, and send fighters to Syria for the IRGC-Qods Force on behalf of Qasem Soleimani," Under Secretary of the Treasury for Terrorism and Financial Intelligence Sigal Mandelker said in the release.
The four individuals were designated under the authority granted by the Hezbollah International Financing Prevention Amendments Act of 2018, which was signed into law on Oct 25, the Treasury said.
Meanwhile, the State Department said in a press release that it designated the Al-Mujahidin Brigades and Jawad Nasrallah for committing acts of terrorism that threaten US national security.
Nasrallah is the son of Hezbollah leader Sayyed Hassan Nasrallah and a rising member of the Lebanese resistance group, the State Department noted.
The State Department said it sanctioned the Al-Mujahidin Brigades, a militant group which operates in the Gaza Strip, West Bank and Egypt, over its attacks on Israeli targets and ties to Hezbollah.
The State Department's actions were part of the Trump administration's snapback sanctions on Iran, the release added.
The sanctions were introduced after at the end of October US President Donald Trump has signed the legislation, allowing to impose additional sanctions on Hezbollah and honoured those killed in the attack on a US marine barracks in Lebanon 35 years ago.
