The U.N. says more than 110,000 displaced people have in recent days left settlement camps in eastern Congo's cities controlled by Rwanda-backed rebels after the rebels were accused of forced camp closures.

Analysts say the deadly march by Rwanda-backed rebels across eastern Congo could widen into a regional conflict drawing in even more countries, and two neighboring nations with the most involvement in the mineral-rich area might be the key to stopping the violence.

(Reuters) -Representatives of Congo's powerful Catholic church met on Wednesday with a rebel leader whose Rwandan-backed M23 forces last month seized Goma, the biggest city in the country's east, and have continued advancing south.
