Syria: Satellite images show the destruction of Homs

Government forces' continued shelling of the Syrian city of Homs has left some neighbourhoods unrecognisable.

Satellite images taken this March reveal a deserted city centre, destroyed areas and heavy deployment of tanks across the city.

This contrasts to the images shot in August, which showed a busy city of around a million.

The latest imagery, commissioned by Al Jazeera, provides a snapshot of what appears to be an increasingly dire situation.

UN observers have so far asked to be allowed in Homs to provide an assessment, but the government has so far refused.
