The condition of the Democratic Republic of Congo (DRC) is fluctuating daily and the situation in two Kivu provinces remains fragile despite the gradual removal of rebel group M23 forces, a UN spokesperson said Wednesday.

"In North Kivu, the withdrawal of the M23 has continued," Martin Nesirky, spokesperson to the UN secretary-general, told reporters at a daily briefing.

The Congolese army is deploying back to Sake, west of Goma, capital city of North Kivu, Nesirky added.

In South Kivu province, the United Nations Organization Stabilization Mission in the DRC (MONUSCO) is supporting FARDC ( Military of the Democratic Republic of the Congo) military operations to counter armed group activity in Bunyakiri, Hombo and Kilembwe areas," he said.

Moreover, "population movements have started to stabilize," Nersirky said. "Some 130,000 people are sheltering in 12 sites in and around Goma. Another 47,000 newly displaced people have arrived in Minova and Bweremana in the last two weeks."

"Also, Congolese authorities announced the re-opening today of the airport in Goma and MONUSCO and humanitarian partners are working on flying in urgently needed humanitarian supplies," he added.

Despite the withdrawal of M23 rebels and some good signs of stability, the humanitarian and protection situation remains extremely worrying in North Kivu, according to the spokesperson.

The Mugunga III camp, which hosts some 30,000 internally displaced persons, was violently looted by armed men during the night between Dec. 1 and 2, Nesirky said.

Some 70 rapes have also been recorded by health facilities in the Minova area, he added.

The M23 is a rebel group composed of soldiers that broke away from the DRC national army in April and contributed to an extremely worrying humanitarian situation in the country.

According to UN reports, the rebel group is responsible for extensive human rights abuses, including the recruitment of child soldiers, executions and acts of sexual violence.

The United Nations Security Council adopted a resolution late November strongly condemning the attacks by the M23 rebels and demanding an immediate withdrawal from Goma.
