A new United Nations report estimates that the 12-year conflict in north-east Nigeria has contributed to the deaths of nearly 350,000 people – more than 90% of whom are children.

The UN Development Programme says that for every person killed directly in the fighting, at least nine other lives are lost because of the impact of the war.

Since the Islamist group Boko Haram launched its first attacks in 2009, close to two million people have fled their homes in the three states of north-east Nigeria.

Agricultural production has been hit hard, leading to disease and hunger. Facilities including health centres and schools have been destroyed or become inaccessible.
