The Nigerian government on Saturday vowed to keep fighting violent extremism and said it hoped Washington would remain a close ally after President Donald Trump added the West African nation to a U.S.

Northern Nigeria has endured years of insecurity as jihadist groups and armed criminals terrorise communities, forcing thousands to flee their homes. A recent social media post claims to show a video of the Islamic State West Africa Province (ISWAP) in a north-central Nigerian state with seized military assets.

Some of the officers suspected to be involved in the coup plot include a brigadier general, a colonel, four lieutenant colonels, five majors, two captains, a lieutenant, a lieutenant commander and a Squandron Leader.
