Daesh earned $500 million illegally selling oil, US Treasury Secretary Jacob Lew said at a meeting of the UN Security Council.
"At the moment Daesh has reaped an estimated $500 million from black market oil and millions more from the people it brutalizes and extorts," RIA Novosti cited him as saying.
Lew noted that Daesh has vulnerabilities and the United States is hitting its financial facilitators.
