Thousands of Congolese civilians are on the move after rebel M23 troops fought with government forces for control of the town of Sake.
The rebel assault on Sake comes days after the M23 seized control of Goma, the biggest city in the North Kivu province in the Democratic Republic of Congo.
There are fears the conflict may spread in the unstable region after the M23 ignored calls from Uganda, Rwanda and the DR Congo to leave Goma and threatened to march on Kinshasa.
In the capital, protesters accused the M23 of abuses, including the rape of pregnant women. The UN has reported killings and kidnappings.
The UNHCR has expressed fears for the wellbeing of those displaced, especially children and other vulnerable groups.
Jean-Marie Runiga from the M23 political wing is in Kampala, Uganda for talks ahead of a summit of leaders from Africa’s Great Lakes region to discuss the escalating situation.
