Attacks on two camps for displaced people in eastern Congo’s North Kivu province on Friday killed at least 12 people, including children, according to local officials, an aid group and the United Nations. The UN called the attacks a “flagrant violation of human rights and international humanitarian law and may constitute a war crime”. The Congolese army blamed the attacks on an alleged rebel group, known as M23, with links to Rwanda, while M23 denied involvement. UN experts and the US State Department have accused Rwanda of backing the M23, but Rwanda denies the claims.
