The United States has imposed sanctions on a Turkish businessman suspected of amassing hundreds of millions of dollars by trading in oil coming from the Islamic Revolutionary Guard Corps, world agencies reported, cited by BTA.

Sutka Ayan, who is close to Turkish President Recep Tayyip Erdogan, as well as his son and one of his closest associates, were blacklisted by the US Treasury Department.

Their assets were frozen in the US and they were barred from accessing major financial markets.

The Treasury Department accuses Ayan of coming to the aid of the al-Quds Force, an elite arm of the IRGC, by arranging the sale and supply of oil under their control to China, other buyers in Southeast Asia, Europe and the United Arab Emirates emirates.

He also contributed to the transfer of the proceeds from these sales to the accounts of the IRGC.

According to the finance ministry, Ayan used the network of his holding company ASB, registered in Gibraltar, to hide the origin of the oil and the purpose of the payments.

The businessman also resorted to one of his companies to buy a Panamanian-flagged tanker for the IRGC.

Bahadin Ayan, one of Sutka Ayan's sons, and Kassam Yotzas, one of the senior figures in the ASB holding, who personally dealt with most of Ayan's cases, were also placed on the sanctions list.

The Ministry of Finance also placed about 20 companies from the ASB holding and from the businessman's network on its blacklist.
