The U.S. and some of its Arab coalition partners have conducted another round of airstrikes in Syria, hitting oil refineries that have fallen into the hands of Islamic State militants, who officials say are funding themselves with the petroleum revenues.
The Pentagon says 13 airstrikes hit a dozen “modular” oil refineries in eastern Syria. The refineries are thought to produce $2 million of refined petroleum each day for the self-declared Islamic State, also known as ISIS or ISIL.
ISIS captured most of Syria’s oil fields earlier this year and it is believed that the group is smuggling oil out and selling it on the black market in order to help fund its military operations.
