At least 55 people were killed in two Boko Haram raids this week near Maiduguri, capital of restive northeastern Nigeria Borno state, a vigilante and two residents said on Friday. "Boko Haram militants raided Bale and Kayamla villages where they killed at least 55 people and burnt several homes after looting them before proceeding to the outskirts of Maiduguri where they were crushed by troops," a vigilante official, Abacha Zinnari, said.
