Syrian children have released a video on Twitter on Friday amid the chaotic atmosphere during the continuing evacuation operation, which has drawn much attention on the social media platform.

In the footage, Syrian boys tell the camera "We're now leaving Aleppo, but we'll come again when we grow up and we'll free Aleppo. All my brothers and I together will return and save Aleppo." The words have prompted emotional tweets in reply.

The evacuation operation, which aims to move injured civilians and moderate opposition members from eastern Aleppo which is under the attack of pro-regime Iran-backed forces, started on Thursday.

But, as the footage shows, the Syrian children, who have suffered traumatic experiences since the beginning of the deadly Syrian civil war, are still unable to feel comfortable, despite the rescue operation.

Syrian children have witnessed the deaths of thousands, often including their parents or relatives, bomb shelling and sounds of explosions or fire.

Meanwhile, the operation of the evacuation of civilians and moderate opposition has been suspended, regime officials said on Friday. The news came minutes after Reuters said explosion sounds were heard at the location from where evacuation buses were departing.

Following the suspension, pro-regime Iran-backed militias reportedly opened fire on the evacuation convoy, and then took 800 hostages after attacking the convoy.

The operation had previously been sabotaged by the Iran-backed militias, killing four civilians and wounding several people on Thursday when the first evacuation convoy departed from Aleppo.

The sixth evacuation convoy carrying wounded civilians and opposition fighters was enroute to Idlib, and around 7,500 civilians and opposition fighters have been evacuated, officials said on Friday.
