Exhausted families trudged out of the Islamic State group's last bastion in eastern Syria Tuesday, as Kurdish-led forces boxed holdout jihadists into an ever-shrinking pocket.
Hundreds fled at night but hundreds more during the day as plumes of grey smoke billowed into the sky over Baghouz, where diehard IS fighters are making their last stand.
After a pause of more than a week to allow out civilians, the Syrian Democratic Forces (SDF) declared a last push to retake the pocket from the extremists on Saturday.
Aided by the warplanes and artillery of a US-led coalition, the Kurdish-led alliance has pressed into a patch of less than four square kilometres (one square mile).
Most of the neighbourhoods visible along the hazy horizon are under their control, but the southernmost parts of the town -- from which sounds of a firefight can be heard -- are still held by IS.
Suddenly, black dots appeared on the dirt road that snakes across the plain from the ruins of the little town.
There are no other NGOs or UN agencies at the site.
Half a dozen among the new arrivals were adult men. The rest were young children with dirty hair and women panting heavily after their odyssey out of Baghouz.
About half of them were Ukrainian or Russian women and their children, while most of the others were Syrian.
Once there, she married an Azeri IS member and had two other children.
"They are all fatherless now," she told AFP in broken Arabic, her voice shaking.
"The progress is slow and methodical as the enemy is fully entrenched and IS fighters continue to conduct counter attacks," he said.
"The coalition continues to strike at IS targets whenever available." - 'Six hours? In the cold?' -
On Monday, the Observatory said a coalition air strike killed 16 civilians. An Italian journalist was also wounded as he covered the clashes and evacuated for treatment, a colleague said on Twitter.
The SDF launched the battle to expel IS from the eastern province of Deir Ezzor in September, slowly tightening the noose around the jihadists and their families since December.
In the past two months, more than 37,000 people, mostly wives and children of jihadist fighters, have fled into SDF-held areas, the Observatory says.
That figure includes some 3,400 suspected jihadists detained by the SDF, according to the Britain-based monitor.
At a gathering point for new arrivals, dozens of men knelt on the ground. Iraqi and Syrian women and children prepared to make the long journey north to a Kurdish-held camp for the displaced, after spending the night in tents.
A very thin child with dark circles around his eyes stumbled onto a truck, as other children screamed out for water and their mothers asked how long the drive would take.
"Six hours? In the cold?" shouted a wrinkled Iraqi woman.
The SDF on Saturday said up to 600 jihadists could still be inside the pocket, adding their leader Abu Bakr al-Baghdadi was likely not there.
At the height of their proto-state, Baghdadi's followers implemented their brutal implementation of Islamic law in an area the size of Britain.
But various offensives, including by the SDF and Russia-backed regime forces, have taken back all but a speck of that territory near the village of Baghouz.
Once the "caliphate" is declared over, the fight will continue to tackle IS sleeper cells, the SDF and their allies have said.
"Soon it will be announced, soon, maybe over the next week, maybe less," he told a rally in the US city of El Paso.
