The Democratic Republic of Congo's government has rejected an ultimatum by rebels to start talks, as fighting continues near the city of Goma.
Rwanda, which denies arming the rebels, has accused Congolese forces of deliberately firing into its territory.
The M23 rebels have advanced to within a few kilometres of Goma, the main city in eastern DR Congo, causing tens of thousands of residents to flee.
The rebels have given government troops 24 hours to withdraw from Goma.
Gabriel Gatehouse reports from Goma.
