A BBC team has witnessed the devastating effects of air bombardment on Syrian civilians after gaining rare access to rebel-held areas of Aleppo.
Thousands of people are reported to have been killed or maimed in a campaign of aerial bombardment in northern Syria this year.
The BBC's Ian Pannell and Darren Conway are the first Western broadcasters in rebel-held Aleppo this year.
