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

Thousands of families have been displaced by violence in eastern Congo, where Rwanda-backed rebels last month seized the key city of Goma in a blitz offensive in the mineral-rich region.

The march by Rwanda-backed rebels across eastern Congo risks escalating into a regional conflict, with countries such as Burundi, Uganda, and Tanzania already involved. Despite diplomatic efforts, tensions remain high.
