The US Treasury Department on Thursday issued new Hezbollah-related sanctions, designating Lebanese businessman and the Iran-backed group's financial facilitator, Ahmad Jalal Reda Abdallah, and his companies.

Abdallah, five of his associates and eight of his companies in Lebanon and Iraq were sanctioned and added to the sanctions list of the US Treasury Department's Office of Foreign Assets Control, the department said.

Abdallah is a Hezbollah official and an active member of its global financial network, according to the Treasury. He has supported Hezbollah for decades, carrying out commercial activities in various countries where the profits are transferred to the Iran-backed group, the department said.

The United States said Abdallah used his senior employees and relatives to establish new businesses throughout the Middle East on behalf of Hezbollah.
