Boko Haram leader killed on direct orders of Islamic State

Isis ordered death of Abubakar Shekau over concerns about indiscriminate targeting of believers'

The death of the leader of the Nigerian militant Islamist group Boko Haram has been confirmed by a rival extremist faction that said it carried out the killing on the direct orders of Islamic State's leadership thousands of miles away in the Middle East.

Abubakar Shekau, one of the most infamous leaders of Islamic militant groups anywhere in the world, died last month after detonating an explosive device while being pursued by fighters from the Islamic State West African Province (Iswap). The Iswap fighters had stormed the Sambisa forest, a swath of strategically important dense forest in Nigeria's north-east, which was Shekau's base.
