Local leaders have accused a Ugandan rebel group, known as the Allied Democratic Forces, of killing civilians in an eastern town. Large parts of eastern DRC are in the grip of armed militias.
Islamist rebels hacked to death at least 22 civilians in Beni, a town in the east of the Democratic Republic of Congo (DRC), local officials said on Sunday
The attack, which was carried out overnight Saturday, was blamed on rebel fighters from the radical Islamist Allied Democratic Forces (ADF), according to Noella Katsongerwaki, civil society president in Beni.
"The enemy operated silently. We have already found 22 bodies and the search continues," Katsongerwaki told German press agency dpa.
The victims were farmers and included 13 women, Agence France-Presse reported, citing Katsongerwaki.
UN peacekeepers
The ADF, an Islamist-rooted militia formed in Uganda in 1995, is one of a wide variety of armed groups operating in the region.
It repeatedly carries out attacks around Beni. It has been accused of killing thousands of people, including UN peacekeepers.
More than 100 people have died in assaults blamed on the ADF since the start of November.
The ADF has a long rap sheet of human rights abuses and is thought to be entwined in criminal networks funded by kidnappings, smuggling and logging.
The United Nations has tried to stabilize the country for the past 20 years with one of the world's biggest UN peacekeeping forces, known as MONUSCO.
MONUSCO comprises more than 16,500 military personnel and observers, 1,300 police and at least 4,000 civilians.
Residents of Beni accuse MONUSCO of failing to protect them against the ADF.
MONUSCO is the biggest and most expensive UN peacekeeping mission in the Democratic Republic of Congo. This is only one of the many other African countries where the "blue helmets" are intervening.

DR Congo: UN's largest mission
Since 1999, the UN has been trying to pacify the eastern region of the DR Congo. The mission known as MONUSCO has nearly 20,000 soldiers and an annual budget of $1.4 billion (1.3 billion euros). Despite being the largest and most expensive mission of the United Nations, violence in the country continues.

Darfur: Powerless against violence
UNAMID is a joint mission of the African Union and the UN in Sudan's volatile Darfur region. Observers consider the mission a failure. "The UN Security Council should work harder at finding political solutions, rather than spending money for the military's long-term deployment," says security expert Thierry Vircoulon.

S.Sudan: Turning a blind eye to fighting?
Since the beginning of South Sudan's civil war in 2013, nearly 4 million people have been displaced according to the UN. Some of them are being sheltered in UN compounds. But when clashes between government forces and rebels broke out in the capital Juba in July 2016, the blue helmets failed to effectively intervene. Later, the Kenyan UNMISS commander was sacked by former UN chief Ban Ki-moon.

Mali: The most dangerous UN mission in the world

But Islamist terrorist groups such as AQIM continue to carry out attacks making MINUSMA one of the UN's most dangerous military intervention in the world. Germany has deployed more than 700 soldiers as well as helicopters.

CAR: Sexual abuse scandals making headlines
MINUSCA, the UN's mission in Central Africa Republic has not helped to improve the image of the United Nations in Africa. French troops have been accused of sexually abusing children by the Code Blue Campaign. Three years on, victims haven't got any help from the UN. Since 2014, 10,000 soldiers and 1,800 police officers have been deployed. Violence in the country has receded but tensions remain.

Western Sahara: Hope for lasting peace
The UN mission in the Westsahara known as MINURSO has been active since 1991. MINURSO is there to monitor the armistice between Morocco and the rebels of the "Frente Polisario" who are fighting for the independence of the Western Sahara. In 2016, Morocco which has occupied this territory since 1976, dismissed 84 MINURSO staff after being angered by a statement from the UN Secretary-General.

Ivory Coast: Peaceful end of a mission
The UN mission in Ivory Coast fulfilled its objectives on June 30, 2016 after 14 years. Since 2016, the troops have been gradually withdrawn. Former Secretary-General Ban Ki-moon said this was a "turning point for the United Nations and the Ivory Coast." But only after the full withdrawal will it be clearly known whether or not the mission was successful on a long-term basis.

Liberia: Mission accomplished
The UN deployment in Liberia is - as in neighboring Ivory Coast - will soon be history. The soldiers are leaving by mid-2017. Since the end of the 14-year civil war, UNMIL has ensured stability in Liberia and helped build a functioning state. Liberia's government now wants to provide security for itself. The country is still struggling with the consequences of a devastating Ebola epidemic.
