Civilians fleeing shattered Aleppo face being pursued and persecuted once again in the rebel stronghold where they will begin to rebuild their lives.
The fall of the rebel-held enclave in east Aleppo has drawn the world's condemnation - but the vicious battle may well be repeated in a fragmented Syria.
Four main groups - the main rebel opposition, government forces, so-called Islamic State and Kurdish fighters - all control different areas of the country.
There is also a risk that the messy conflict could destabilise the entire region.
And there were warnings that the rebel stronghold of Idlib, where most evacuees from Aleppo are being taken, could emerge as a new target.
The UN envoy for Syria warned: "If there isn't any agreement on a ceasefire and there is no political discussion then Idlib is the next Aleppo."
Tens of thousands of civilians desperate to leave Aleppo were left stranded for 48 hours over the weekend after a ceasefire deal broke down.
