Aleppo teacher: 'It's Doomsday in rebel-held east'

In an interview with the BBC's Victoria Derbyshire, an English teacher inside one of the remaining rebel-held areas of Aleppo said it felt like "Doomsday" as government forces advanced.

"Bombs are everywhere," Abdul Kafi Alhamado said, "People are running, people are injured in the streets, no-one can dare go to help them, some people are under the rubble."
