The US is trying to establish control over Syrian oil fields, Syrian Deputy Defense Minister Mahmoud al-Shawa said, speaking at the Moscow Conference on International Security.
According to some US defence and administration officials, the Pentagon had been discussing the deployment of additional troops to northern Syria.
The militia of the Syrian city of Raqqa fired mortars on the US led coalition base in the town of Ayn Issa.
According to the source, citizens of Mansureh town and Western Raqqa surrounding area clashed with US-backed SDF.
According to the source, at least 12 ISIS terrorists were released by the US-backed fighters from jails in Raqqa.
The citizens of Raqqa who have returned to their homes live under the constant risk of death due to land mines and improvised explosive devices (IEDs) which still remain in the city four months after it had been liberated from ISIS.
Hundreds of civilians have been killed and injured by IEDs and landmines that remained in the city after the defeat of the Islamic State by the US-backed Syrian Democratic Forces (SDF).
