Nigeria’s army says it fought off an overnight militant assault on a base in the country’s northeast and killed at least 60 attackers. The army says the attack happened on Wednesday in Mallam Fatori in Borno state, near the border. A spokesperson says troops expected the raid and responded with ground fire and air support. The military blames suspected Boko Haram fighters or their Islamic State-linked offshoot. The claim is not independently verified. The clash follows recent suicide bombings in Maiduguri that killed at least 23 people. The long insurgency has stretched Nigeria’s forces, and the U.S. has sent troops to advise.
