Syria crisis: Sounds return to shattered city of Homs

Last week rebel fighters completed their withdrawal from Homs, marking the end of three years of resistance in Syria's third city, once dubbed the "capital of the revolution".

Residents are now trickling back into the ruins of their home town, but on Tuesday UN mediator Lakhtar Brahimi said he was stepping down - with no end in sight to the three-year conflict in Syria.

The BBC's Lyse Doucet is one of the few journalists to have visited Homs since the government took full control, and sent this video report.
