The United States on Wednesday blacklisted four men and three entities for their involvement in money laundering for Lebanese drug lord Ayman Joumaa, and another man for raising money for the militant group Hezbollah.

The Department of Treasury targeted Abbas Hussein Harb and Ibrahim Chibli for sanctions as they were accused of moving millions of U.S. dollars in narcotics-related proceeds for Joumaa.

It said Harb uses his organization based in Colombia and Venezuela to launder money for the Joumaa network through the Lebanese financial sector, while Chibli used his position as the manager of the Abbassieh branch of Fenicia Bank in Lebanon to facilitate the movement of money for Joumaa and Harb.

Ali Mohamad Saleh, a Lebanese Colombian national, was branded as a specially designated global terrorist for raising money in the Americas for Hezbollah, the Shiite militant group that dominates the Lebanese government but is deemed as a terrorist group by the United States and the European Union.

Saleh was blacklisted by Washington in December 2011 for his role as a money launderer in Maicao, Colombia for the Cheaitelly/ El Khansa criminal organization, which is linked to the Joumaa network.

As for Ali Houssein Harb, Abbas Hussein Harb's brother, and Kassem Mohamad Saleh, Ali Mohamad Saleh's brother, they were targeted for their links to the Joumaa network. The Treasury said the pair are dual citizens of Lebanon and Venezuela.

The three companies targeted are Importadora Silvania and Bodega Michigan, both based in Colombia, and Importadora Silvania, C.A., based in Venezuela. They are owned or controlled by Abbas Houssein Harb and Kassem Mohamad Saleh, the Treasury said.

"The Joumaa network is a sophisticated multinational money laundering ring, which launders the proceeds of drug trafficking for the benefit of criminals and the terrorist group Hezbollah," said Under Secretary of Treasury for Terrorism and Financial Intelligence David Cohen.

"We and our partners will continue to aggressively map, expose and disable this network, as we are doing with today's sanctions," he said in a statement.

Ayman Joumaa was targeted for sanctions in January 2011 for his role as a high-level money launderer and drug trafficker operating in the Americas, Middle East, Europe and Africa.

The Treasury accused him and his network of laundering as much as 200 million dollars per month in proceeds from their illicit activities through various channels, including bulk cash smuggling operations and Lebanese exchange houses.

Internationally, the Treasury has targeted more than 1,100 individuals and entities for sanctions for their links to drug kingpins since June 2000.
