Syrian troops withdrew from Omar oil field, one of the last regime positions east of Deir Ezzor city near the Iraqi border, a watchdog said Friday, adding that rebels now control the country's major fields.
Rebels last week seized the strategic town of Mayadeen, taking control of a huge stretch of territory east of Deir Ezzor city along the Iraqi border. This area is now the largest outside regime control.
The insurgents took control of an oil field for the first time on November 4 when they overran Al-Ward, the most important in the province, the Observatory said.
After also losing control of Al-Jofra field also in November, the army now controls not more than five fields, all located to the west of Deir Ezzor city, the watchdog said.
Deir Ezzor province contains the largest energy reserves in the country.
