Rebels appear to be edging closer to taking control of the key city of Goma in the east of the Democratic Republic of Congo following reports that they had captured its airport.
The Congolese government has insisted that it is still in charge as fighting in parts of the city continues. Warehouses with food and medical supplies have been looted, aid agencies say.
Clashes between M23 rebels and the army and its allies have left hospitals overwhelmed by casualties and bodies lying on streets, according to the UN.
Growing anger over the rebel offensive led to protesters targeting foreign embassies in the capital, Kinshasa. Calls for peace talks to end fighting are mounting.
Neighboring Rwanda has been accused of backing Tutsi-led M23 as it made a rapid advance in recent months across mineral-rich regions.
