Largest Syrian oil field taken from ISIS

United States-backed militia fighters seized Syria’s largest oil field from ISIS, according to the militia, narrowly beating pro-government forces to an area critical to the war-torn country’s economy.

Although it is unclear what the capacity of the oil field is today, after years of airstrikes by the coalition on the ISIS's makeshift oil operations, its capture is a major blow to the militant group, which is losing both territory and sources of revenue.

The Omar oil field that was seized on Sunday is a major prize in that competition. Local witnesses, as well as conflict monitoring groups, said that pro-government forces had been within a few miles of the oil field but retreated after heavy attacks by ISIS, the New York Times reported.
