On Tuesday the groups issued a report saying more than 1,000 civilians have died and nearly 900,000 others have been displaced by fighting between UN-backed Congolese government forces and Rwandan Hutu rebels.
The report sharply criticized peacekeepers with the UN mission, known as Monuc, for supporting a deadly government offensive against the rebels.
"The human rights and humanitarian consequences of the current military operation are simply disastrous," Marcel Stoessel, of the UK-based aid agency Oxfam, said.
"UN peacekeepers, who have a mandate to protect civilians, urgently need to work with government forces to make sure civilians get the protection they need, or discontinue their support."
