Aleppo Under Siege: Then and now

Two videos taken in the besieged Syrian city of Aleppo has shown the devastating effect of the country's civil war.

The videos, taken five years apart and placed side-by-side, contrast a once-thriving city - full of shoppers, traders and children playing - to the badly damaged and destroyed buildings of the current day.

Thousands of people were filmed thronging a main square, releasing balloons and celebrating in 2011 - whilst aerial footage taken earlier this year show abandoned streets strewn with craters and debris from bombed-out buildings.

Video footage of children playing in one of Aleppo's parks just three years ago contrast sharply to the image of a Ghazal Qasim - a five-year-old child who was the sole survivor of a Syrian airstrike last month.

Daily airstrikes by the Syrian government has caused an international refugee crisis and has led to the population to dwindle from 2.3 million to 250,000.

The World Health Organisation has said that between September 23 and October 2 this year, 342 people have been killed in the city - 106 of them children.

They claim a further 1,129 have been injured, including 261 children.
