A survivor hidden in a tree says he watched Boko Haram extremists firebomb huts and heard the screams of children burning to death, among 86 people officials say died in the latest attack by Nigeria's homegrown Islamic extremists. Scores of charred corpses and bodies with bullet wounds littered the streets from Saturday night's attack on Dalori village and two nearby camps housing 25,000 refugees, according to survivors and soldiers at the scene just 5 kilometers (3 miles) from Maiduguri, the birthplace of Boko Haram and the biggest city in Nigeria's northeast.
