The president of the Democratic Republic of Congo has ruled out political negotiations with the M23 rebel group.

As part of an internationally brokered peace deal the group has been withdrawing from areas it had captured.

President Félix Tshisekedi said according to the agreement the M23 rebels are to demobilise before returning to civilian life.

The group – which is widely reported to be backed by Rwanda – had previously said it was expecting negotiations with the Kinshasa government.
