Fresh fighting was reported to have broken out between government troops and rebels in the east of the Democratic Republic of Congo. The clashes, about 60 kilometres west of the town of Goma, came as aid agencies struggled to help tens of thousands of displaced people.
Observers say efforts to distribute relief supplies over the weekend have mostly failed, despite an appeal by African leaders for a ceasefire.
The UN is calling for the setting up of a humanitarian corridor, urging Tutsi rebels and pro-government militias to leave the North Kivu town of Rutshuru, north of Goma. This after reports of a spate of killings on both sides.
The campaign by rebels against the DRC government has displaced over a million people in North Kivu over the past two years, and a quarter of a million since September alone. The Tutsi rebels accuse the government of siding with local militias and Rwandan Hutu rebels against the minority Tutsi community.
