'Besieged' Homs endures tank assault

The Syrian military is reportedly moving deeper into residential areas in the city of Homs, a day after the Russian foreign minister said President Bashar al-Assad was "fully committed" to ending the bloodshed.

Activists said the army was firing rockets and mortar rounds to subdue opposition districts on Wednesday, as tanks entered the Inshaat neighbourhood and moved closer to Bab Amr.
