Oil used to be a major source of revenue for the regime of President Bashar Assad before the European Union and the United States imposed an embargo on Syria's crude exports last year.
Syrian rebels firing mortars and rocket-propelled grenades captured an oilfield in the country's east on Sunday after three days of fierce fighting with government troops protecting the facility, activists said.
The head of the Britain-based Syrian Observatory for Human Rights, Rami Abdul-Rahman, said rebels overran the Al-Ward oilfield in the province of Deir el-Zour near the border with Iraq early Sunday. About 40 soldiers were guarding the facility that the rebels had been pounding for the past three days, he said, adding that opposition fighters also captured several regime troops.
Oil was a major source of revenue for the cash-strapped regime of President Bashar Assad before the European Union and the United States imposed an embargo on Syria's crude exports last year to punish the government for its brutal crackdown on protesters early on in the uprising.
"This field used to supply the regime with fuel for its tanks and our aim was to stop these supplies," Omar Abu Leila, an activist in Deir el-Zour, told The Associated Press by telephone. He said there was heavy fighting recently near the oil facility that is located just east of the city of Mayadin.
Both activists said the rebels shot down a fighter jet near the oil field Sunday. It was not clear if the warplane was taking part in fighting in the area.
Abu Leila said that the oilfield had been functioning up until shortly before the rebels seized it. It was not clear whether the facility was damaged in the fighting or sabotaged by regime forces.
Analysts say the rebels would not benefit economically from capturing the oil filed, although the opposition's latest conquest could reduce crude supplies available to the government.
