“Two jihadist groups have for weeks been engaged in deadly clashes in their northeast Nigeria strongholds according to security sources and residents, who said hundreds of fighters had died. Boko Haram militants have been fighting government troops for almost 14 years in a bid to establish an Islamic caliphate in the region. But they have also been fighting against rival jihadists from the Islamic State West Africa Province (ISWAP) group, who emerged in 2016. Clashes initially started over ideological differences, with ISWAP objecting to Boko Haram's indiscriminate killings of Muslims.”
