The Congolese government says soldiers are hunting down the last remaining M23 rebels in the country.

Government spokesman Lambert Mende said Friday that the remaining rebels are by three hills near Congo's borders with Uganda and Rwanda.

For the first time in an 18-month rebellion, the Congolese military has recently retaken most of the land that was under the control of the M23.

Mende said Friday that the government will pursue an offensive against those who remain unless they put down their arms.

Critics, though, have warned that M23 elements could regroup and re-emerge if they get additional help from the government of neighboring Rwanda.

Rwanda denies helping the rebels, though a United Nations experts group has published its evidence that Rwanda has provided weapons and other aid.
