At least 14 U.N. peacekeepers have been killed and 53 wounded in an attack in the east of the democratic republic of Congo.

The UN’s Monusco mission said the peacekeepers were attacked by suspected rebels of the allied democratic forces in North Kivu province.

Five Congolese soldiers also died.

UN Secretary-General Antonio Guterres said it was the worst attack on UN peacekeepers in recent history and amounted to a “War Crime”.

Eastern Dr Congo has suffered years of instability with rival groups fighting for control of territory.
