The government of the Democratic Republic of Congo has expressed alarm as rebel forces advance towards the country's main eastern city of Goma.

Witnesses told the BBC that rebels of the M23 group were 40km (25 miles) from the city, near the Rwandan border.

They said rebels appeared to be taking towns and villages with ease, with government troops usually melting away.
