Hunger fears in north-east Nigeria as roaming elephants trample crops

Animals have ventured back into areas largely emptied of people by Boko Haram insurgency

A herd of hundreds of elephants that have returned to north-east Nigeria are under threat from jihadist groups and increasingly in conflict with thousands of refugees whose crops they have trampled weeks before harvest.

More than 250 elephants ventured last month from Chad and Cameroon into Kala-Balge, a district in Nigeria's Borno state.
