ISIS makes over $3 million every day from 11 oil fields it controls. Oil is sold to Turkey, Iraq and Jordan for $25-$60 per barrel (the world oil price is over $100 per barrel), ITAR-TASS reports.
Washington is reluctant to destroy the petroleum infrastructure, as it may cause major civilian losses.
Besides income from oil sales, ISIS makes money from robberies, human trafficking and hostage- taking.
