A survivor recounts the deadly attacks in Nigeria

STORY: It was the bloodiest violence since 2018 when more than 200 people were killed in Nigeria's central region where clashes between herders and farmers are common.

It was not immediately clear what triggered Sunday's attacks but violence in the region, known as the "Middle Belt," is often characterized as ethno-religious - chiefly Muslim Fulani herdsmen clashing with mainly Christian farmers.

But experts and politicians say climate change and expanding agriculture are creating competition for land, pushing farmers and herders into conflict.

Nomadic cattle herders are from northern Nigeria, which is getting drier and becoming more prone to drought and floods. That is forcing them to trek further south, where farmers are increasing production as the population rapidly expands.

That means less land for nomads and their cattle, supporting the view among local people that the conflict is based on the availability of resources rather than ethnic or religious differences.
