US airstrikes meant to hit ISIL targets in Syria have killed at least five civilians, says a foreign-backed Syrian opposition group.
The civilians, including one child, were killed in the airstrikes on ISIL positions in northeastern Hasakeh, said the so-called Syrian Observatory for Human Rights.
The group said fourteen militants have also been killed in the raids on the eastern province of Deir Ezzor.
Observatory director Rami Abdel Rahman said at least one militant checkpoint was hit during the overnight attacks. The raids targeted oil facilities captured by the ISIL.
On Wednesday, US officials announced that Washington and its Arab allies had resumed airstrikes on the ISIL positions, which had begun a day earlier.
Meanwhile, a senior Kurdish commander in the town of Kobani at the Turkish border said that the terrorists have mobilized in the area since the beginning of US-led air strikes. He said the terrorists have increased the number of their militants and tanks since the air raids began in Raqqa.
The militants have seized a series of oil facilities and fields in north Syria. Earlier reports suggest that the group sells oil on the black market to bring in revenue.
