The leader of a rebel alliance that has seized swathes of east Congo told Reuters on Thursday that insurgents were not bound by a ceasefire call from Congo and Rwanda's presidents and cast any minerals-for-security deal with the U.

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.

Rwanda-backed M23 rebels have captured yet another strategic town in the eastern part of the Democratic Republic of Congo, even as the leaders of the two countries called for a ceasefire in the conflict.
