U.S.-backed Syrian forces prepared Monday for another round of evacuations from the Islamic State group's last shard of territory in Syria as conditions worsen in overcrowded camps for fleeing civilians.

Three children, not older than five years old, are languishing in cold and muddy camps for the displaced in Syria's northeast, far away from their family in France.

US-backed Syrian forces are negotiating to evacuate civilians from the Islamic State group's last redoubt which now faces "inevitable defeat", the international coalition against the jihadists said Thursday.

More than 2,500 foreign children from 30 countries who have fled the Islamic State group's last redoubts are living in desperate conditions in camps in northeastern Syria, Save the Children said Thursday.

State Minister for Refugee Affairs Saleh al-Gharib visited Syria on Monday at an official invitation to discuss the refugee file.

Speaking after a meeting with Syria’s Local Administration and Environment Minister Hussein Makhlouf, Gharib said he was “pleased” by Damascus' viewpoint on the refugee file.

Kurdish-led forces said Saturday they were holding up the announcement of final victory over the Islamic State group for "a few days" because the large number of civilians remaining on the battlefield had forced a delay.

U.S.-backed Syrian forces were clearing two villages in eastern Syria on Thursday of remaining Islamic State militants who are hiding among the local population, and detaining others attempting to flee with the civilians, the U.S.-led coalition said.

The coalition said the clearance operations were taking place in the villages of Shajalah and Baghouz, near the border with Iraq.

The cry echoed across the chalk-dry Syrian plain: "Water!" Within seconds, the truck carrying a few dozen bottles was emptied by parched refugees who had spent the night out in the open.

At least 300 women and children, mostly Iraqi, had slept amid the desert scrubs after escaping the Islamic State group's final redoubt of Baghouz in eastern Syria.

U.S.-backed forces pressed the battle to expel diehard jihadists from the last pocket of land under their control in eastern Syria on Tuesday after hundreds fled the holdout overnight.

Umra Abbas Ammour, 60, dreamt of safety as she and her family fled jihadists in eastern Syria, but hours after reaching US-backed forces her son, daughter and granddaughter were all dead.
