By Sonia Rolley (Reuters) -Rwanda-backed M23 rebels staging an offensive in east Congo said on Saturday they would withdraw forces from the seized town of Walikale in support of peace efforts, having previously said they were leaving troops there as they pushed on to the capital.

Rwanda-backed rebels battling Congo’s army have pushed into a strategic, mineral-rich town in the east, ignoring calls for a ceasefire this week by the Congolese and Rwandan presidents as the M23 rebel group expands its footprint in the conflict-torn African country.

After talks in Qatar, the two countries’ presidents said they were committed to an unconditional truce between Congo’s army and a rebel group that Rwanda denies backing.
