Two people died on Monday following violent clashes for a second day in Goma, in the Eastern Democratic Republic of Congo.
Hundreds of demonstrators took to the streets accusing the UN and the East African Regional Force of failing to support the Congolese military operations against the M23 rebel group.
Fighting has intensified in the region in recent days with the group taking key towns in eastern DR Congo.
Protesters took to the streets in several neighborhoods of Goma, in North Kivu province, bringing businesses in the city to a standstill.
Security forces responded by firing tear gas to disperse crowds who pelted stones and threw petrol bombs at the UN headquarters in Goma.
Reports said a church in one of the neighborhoods was demolished during the clashes.
The rebels have captured large swathes of territory in the volatile province in recent days and have threatened to march on to Goma, the region’s commercial hub.
The recent fighting has killed hundreds of people and displaced thousands more with international organizations saying that 122,000 people have fled their homes over the course.
