This comes against the backdrop of sustained offensive by the Syrian in its push to take full control over the city.
United Kingdom-based Syrian Observatory for Human Rights said as many as ten thousand residents fled to government-controlled western areas and a Kurdish-run northern district.
The group also said around two hundred and twenty-five civilians, including twenty-seven children, have been killed in the assault so far.
But the Syrian state media put the number of those who left eastern Aleppo at more than one thousand, five hundred, while Russia is reporting that two thousand, five hundred civilians had left the besieged Aleppo district.
