WASHINGTON, June 15 (Xinhua) -- The U.S. Treasury announced on Friday that it has imposed sanctions on 14 entities for their connections with an already designated Israeli billionaire, accusing them of human rights abuse and corruption.

The punished 14 companies were affiliated with Dan Gertler, an Israeli businessman whom the Treasury claimed had amassed his fortune through "opaque and corrupt mining and oil deals in the Democratic Republic of the Congo (DRC)."

"Treasury is sanctioning companies that have enabled Dan Gertler to access the international financial system and profit from corruption and misconduct," Under Secretary of the Treasury for Terrorism and Financial Intelligence Sigal Mandelker said in a statement.

The sanctions would freeze assets of blacklisted entities under U.S. jurisdiction and ban any U.S. individuals or companies from making business deals with them.

Gertler himself was blacklisted by the U.S. Treasury last December.

The Treasury also said on Friday that the entities were punished under the Global Magnitsky Act, under which 73 individuals and entities have had their assets blocked so far.
