The UN envoy for Syria has said he is unsure how long the fighting in the rebel-held districts of Aleppo would last as it is still intensifying.
The Syrian army and its allies have made huge advances across the besieged eastern Aleppo in recent days with thousands forced to flee their homes.
"Clearly, I cannot deny - this is a military acceleration and I can't tell you how long eastern Aleppo will last," Staffan de Mistura told the European Parliament.
"There is a constant increase of movement on the military side."
