Syrian rebel factions have proposed a five-day ceasefire for medical and civilian evacuation from the eastern part of the city of Aleppo.
The rebel proposal comes as Syrian government and allied forces have gained control of three-quarters of the enclave that the rebels had controlled since 2012.
The ground offensive was preceded by an intensive bombing campaign that knocked out medical facilities and left the civilian population in eastern Aleppo reeling from the onslaught.
The proposal calls for the immediate evacuation of 500 seriously wounded Aleppo residents and for allowing civilians wishing to leave to head to northern rural Aleppo province, where there is almost no government presence.
Captain Abdel-Salam Abdel-Razek, of the rebel Nour el-Din el-Zinki faction, said the future of the city of Aleppo is to be negotiated during this humanitarian pause, which the rebels want the United Nations to monitor.
