Syrian government have seized two new rebel-held areas of Aleppo

Syrian government forces have seized two new rebel-held districts in Aleppo.

It is a day after they retook the largest opposition-controlled neighbourhood in the second city.

It is reported more than 4,000 civilians have fled eastern Aleppo in the past 24 hours.

Earlier, footage emerged apparently showing the aftermath of a Russian airstrike on a pharmaceutical factory in the city.
