The Death toll from Syrian airstrikes on rebel-held areas in eastern Aleppo has risen to at least 25, Sky News channel quoted field sources as saying on Friday.

Meanwhile, the head of the civil defense service in the east of the Syrian city said the sorties had targeted three out of four civil defense centers, putting them out of service.

"Today, we can say our work has stopped because of the lack of fuel, the destruction of the equipment and the intensity of the bombardment," Ammar al Selmo said in statements Friday.
