More than 10,000 people have reportedly left Baghouz in the last several weeks, many of them dramatic stories of what life was like under repressive ISIS rule.
Civilians streamed out of the Islamic State group's last Syrian stronghold Tuesday into territory held by US-backed forces battling to finish off the jihadists' dying "caliphate".
But despite this hinderance, spokesperson for the Kurdish-led Syrian Democratic Forces Mustafa Bali tweeted that the battle to retake Baghouz, the last territory in Syria held by the Islamic State group, was "going to be over soon".
The on-off campaign against IS has progressed haltingly since SDF fighters, backed by U.S. led-coalition airstrikes, cornered IS fighters and began their final push three weeks ago.
"We managed to evacuate about 3,000 people" from the pocket, Mustefa Bali said on Monday night.
But the Kurdish-led force slowed down the offensive on Sunday, motivated by concern for civilians still trapped inside the pocket.
Under the banner of "cooperation, fraternity and clemency", the SDF said it chose to release the IS prisoners following negotiations with tribal leaders who had fought against IS militants.
"We're slowing down the offensive in Baghouz due to a small number of civilians held as human shields", he said.
ISIS soldiers are using civilians as "human shields" in an attempt to slow down USA -backed forces that have cornered the terrorists in the small Syrian town of Baghouz.
Many of the ISIS fighters left inside the town are "foreign recruits, intent on fighting to the end", according to Kurdistan 24. Russia, along with other countries, has been pushing for the formation of a committee to draft a new Syrian constitution.
The Malian-born jihadist claimed his attack, which came a day after two brothers killed 12 people at the offices of satirical publication Charlie Hebdo, in the name of IS.
The numbers of IS fighters detained by the SDF were likely to continue to shift in coming days as the US-backed forces continue to reclaim land from Islamic State, officials said.
Around 90 people, mostly children under the age of five, have died en route to the shelter or shortly after arriving, OCHA said.
ISIS is an alternative acronym for the extremist group.
