The Free Syrian Army or FSA (also called the Syrian National Army), have denied those claims. CNN cannot independently verify the videos.
The SDF who operate in the area are led by the Kurdish People’s Protection Units (YPG), which Turkey considers a terrorist organization affiliated with the Kurdistan Workers’ Party (PKK).
Assad’s soldiers helping Kurdish forces
On Sunday, the Kurdish-led Autonomous Administration of North and Eastern Syria said it reached an agreement with the Syrian government to deploy troops along the entirety of Syrian-Turkish border.
Units from the Syrian Army were moving towards the north Sunday night to “oppose the Turkish aggression” on Syrian territory, according to Syrian state news agency SANA.
The new agreement between the Kurds and Damascus represents a new chapter in the eight-year Syrian war, and one that is throwing up changing alliances in an area already saturated with infighting.
The Kurdish-led Autonomous Administration of North and Eastern Syria said Sunday that the Syrian government had the duty of protecting its borders and sovereignty.
“This agreement offers an opportunity to liberate the rest of the Syrian territories and cities occupied by the Turkish army as Afrin and other Syrian cities and towns,” the statement said.
The Syrian government has not commented on such an agreement.
ISIS families escape from camp
But the offensive threatens gains made against ISIS.
Kurdish authorities claim Turkey’s offensive has led to the escape of “785 people affiliated with foreign ISIS fighters” from the Ain Issa camp. The camp mainly houses internally displaced people and some ISIS family members.
According to a statement posted on the Autonomous Administration of North and East Syria Facebook page, “ISIS elements attacked the camp guards, opened the gates and escaped.” CNN is unable to verify the claims.
Erdogan called the reports of an escape “disinformation” in order to “provoke the US and Europe,” Turkish news agency Anadolu reports.
A European intelligence official questioned the Syrian regime and Russia’s readiness and willingness to take foreign ISIS fighters into custody.
“There is a high chance fighters or their families could attempt to come back to Europe. They could also try and retake the land of the caliphate, disappear back in to ungoverned territory to regroup or a combination of all of that. Dealing with the last two would be a major challenge without a committed ground force as you can’t just use air power,” the official said.
The official added that it was unlikely the SDF would trust the West again.
“ISIS has a second life and our geo-political allies are the ones who have the advantage,” said the official, speaking candidly in a personal capacity about the withdrawal of US troops from Syria. “Russia and (the Syrian) regime will take back all of the territory and Iran has freedom of movement across the region.”
‘Blood on Trump’s hands’
The former commander of American forces in Afghanistan and former special presidential envoy for the Global Coalition to Counter ISIS under the Obama administration, told CNN the unfolding crisis in Syria was “completely foreseeable” and “the US green lighted it.”
“There was no chance Erdogan would keep his promise, and full blown ethnic cleansing is underway by Turkish supported militias,” he said. “This is what happens when Trump follows his instincts and because of his alignment with autocrats.”
The Trump administration has insisted Turkey would have proceeded with their offensive regardless of whether US troops had remained and that the US has not deserted the Syrian Kurds.
