Air strikes, thought to have been carried out by US-led forces, hit bases and positions held by the group calling itself Islamic State in the eastern Syrian province of Deir al-Zor today, a monitoring group said.
The British-based Syrian Observatory for Human Rights said the strikes hit territory on the outskirts of the city of al-Mayadin controlled by IS militants, also known as ISIL and ISIS.
The latest air strikes hit two provinces of Syria overnight, targeting oil facilities for a second day.
SOHR subsequently reported additional strikes this morning on a command centre of the IS group on the outskirts of the town of Al-Mayadin.
The target of the strikes in Hasakeh was not immediately clear, the group’s director Rami Abdel Rahman said.
There were no immediate details of any casualties from the strikes.
They came on a fourth night of bombing by the coalition Washington has assembled to tackle the jihadist Islamic State group in Iraq and Syria.
The strikes have killed at least 140 jihadists and 13 civilians so far, according to the Observatory, though Washington has yet to acknowledge any civilian casualties.
Raids overnight between Wednesday and yesterday also targeted some of the makeshift oil refineries operated by IS and others in Deir Ezzor and Hasakeh.
Black market sales of illegally extracted Syrian and Iraqi oil are believed to account for a large part of the Islamic State group’s funding.
Experts say the group could be earning between $ 1 million and $ 3 million a day from oil sales alone.
