The United States and its Arab allies mounted airstrikes against oil refineries controlled by the Islamic State in eastern Syria for the second straight day, a monitoring group said on Friday.
The Britain-based Syrian Observatory for Human Rights added that the overnight strikes into Friday targeted at least two areas housing oil installations in the province of Deir.
The targets included the major al-Tanak oilfield on the eastern edge of Deir al-Zour bordering Iraq, according to the Observatory’s head, Rami Abdel-Rahman.
The Islamic State seized the field along with others in the area in July when the al-Qaeda splinter group established a foothold in eastern Syria.
U.S. Central Command has said that hitting the fields successfully choked off a source of revenue, said to generate about 2 million dollars a day.
Jets early Wednesday hit military facilities manned by the Islamic State and other militant groups on the outskirts of the town of Mayadeen in Deir al-Zour, the Observatory said.
