Kurdish forces risk turning to 'guerrilla' warfare as Syrian army advances

Kurdish-led forces withdrew from Syria's largest oil field on Sunday, according to a conflict monitor, as government troops expanded their control over vast areas in the country's north and east. As the Syrian army continues to advance into Kurdish-held territories, the Kurdish forces may resort to guerrilla warfare, potentially destabilizing the country, said Henri Barkey, Professor of International Relations at Lehigh University.
