After Nigerian army abandoned town, Boko Haram slaughtered at least 60

It came two weeks after Boko Haram had overrun the same town, driving out Nigerian soldiers and signaling its re-emergence as a force capable of capturing army bases. The bloodshed is a challenge for President Muhammadu Buhari in particular as he seeks a second successive four-year term in an election on Feb. 16, having been elected in 2015 partly on a promise to restore security. A Nigerian army spokesman denied that troops had left the town and that Boko Haram had killed the people.
