Medical and sanitation supplies have been transported by UN troops into rebel-held territory in the Democratic Republic of Congo for some 250,000 people who have been displaced by fighting.
At a camp in Kibati, north of Goma, refugees fleeing fighting between the forces of renegade general Laurent Nkunda and Congolese troops are registered by the Red Cross.
Malnourished and dehydrated, many are so weak they need urgent medical care. Gen Nkunda said he would guarantee "humanitarian corridors" for the aid convoy through rebel lines.
Amid a fragile ceasefire, other people have been trying to return to their homes around Kibati in North Kivu province.
There are reports that some camps have been flattened and of renewed clashes, raising doubts over the ceasefire and concerns about the whereabouts of tens of thousands of people.
