At least five people were killed and around 50 injured in anti-United Nations protests in the eastern Democratic Republic of Congo city of Goma on Tuesday, a government spokesperson said.
Earlier, a Reuters witness saw UN peacekeepers shoot two demonstrators dead.
The violence took place on the second day of protests against the peacekeeping mission MONUSCO for failing to protect civilians in a region marred by decades of militia violence.
Hundreds of demonstrators attacked and looted a MONUSCO warehouse in Goma on Monday, demanding that the mission leave the country.
A Reuters witness said peacekeepers fired live bullets at a largely peaceful crowd on Tuesday, killing two and wounding at least two others.
Army and police officers deployed to the scene did not fire, he added.
A MONUSCO spokesman was not immediately available for comment.
