White Helmets detail Aleppo raids

Warplanes have carried out fresh air strikes on Aleppo, hours after Syria's government announced an offensive to retake rebel-held areas of the city.

Ibrahim Abu-Laith, spokesman for the White Helmets volunteer group in eastern Aleppo, spoke to the BBC from its media office there.

He said Aleppo's residential areas had been targeted to an unprecedented level.
