Evacuations from the Syrian enclave of east Aleppo continued on Wednesday evening, a UN official in Syria said.
Earlier, the Syrian Observatory for Human Rights war monitor said President Bashar al-Assad took control of Aleppo city on Wednesday after the last batch of fighters was evacuated.
But a UN official in Syria, asked about the report, told Reuters: "That is not something we can confirm. Evacuations are still ongoing."
Another aid worker told Reuters that completion of the evacuation aboard buses was expected to be "imminent".
