Militants from the Islamic State group seized control of Syria’s largest oil field from rival Islamist fighters on Thursday, strengthening its advance across the eastern Deir al-Zor province, an opposition monitoring group said.
The capture of the al-Omar oil field gives Islamic State control of crude reserves which could be useful to its advancing fighters, and underlines how the al-Qaida offshoot has eclipsed its militant rivals by capturing territory and assets across Syria and Iraq in the past few weeks.
It has declared an Islamic ‘caliphate’ on lands it has seized in both countries, and urged Muslims worldwide to flock there and wage holy war.
