The president of the Aleppo local council has sent a message to European leaders who are due to meet in Brussels for a summit today (15 December).
Brita Hagi Hasan, who is also the city's major, asked leaders to listen to his testimony and ensure the safe passage of the remaining civilians trapped in eastern Aleppo.
The heads of government of the 28 EU member states, plus European Council president Donald Tusk and president of the European Commission Jean Claude Juncker, are expected to discuss progress on the EU-Turkey deal, the reform of the European asylum system, as well as Russia and the conflict in Syria.
Hasan has been in Europe since the end of November, when he met French foreign minister Jean-Marc Ayrault.
The mayor of eastern Aleppo has been lobbying for an evacuation of civilians and militants. "The civilians are calling for the world to help. In the name of humanity let the civilians leave the city. Help the civilians! Protect the civilians!" he said, speaking at a news conference held on 30 November.
Commenting on the first evacuation deal which eventually fell through yesterday, Hasan said it was "the least worst" solution, but expressed doubts as to its actual implementation.
On 14 December evening, the iconic Tour Eiffel in Paris went dark in a show of solidarity with the people of Aleppo.
A new ceasefire deal was struck overnight and evacuations are due to start on 15 December.
