BBC in Syria: Trapped by raging battle for Aleppo

Syrian government forces have been continuing their assault with artillery, ground forces and helicopter gunships on rebel-held areas of the second city, Aleppo.

Officials said one area, Salah al-Din, had been recaptured, but rebels said the battle there was still going on.

UN observers have reported an upsurge in violence in the city.

The BBC's Ian Pannell and cameraman Darren Conway were trapped by fighting in Aleppo, from where they sent this report.
