Nigerian Student Hears Captors Ask, 'Should We Release or Kill Them?' Sani Malumfashi KANKARA, KASINA STATE, NIGERIA - Marching at gunpoint in a forest in Nigeria's northern Katsina state, Usama Aminu Mali wondered whether he and hundreds of other abducted schoolmates would survive. The 18-year-old said he overheard one of his captors ask in a phone call, "Sir, should we release or kill them?" The order came through: Keep walking. Relieved, Usama kept moving and praying. He was rescued Sunday morning, 30-some hours after gunmen on motorcycles raided the all-male Government Science Secondary School near Kankara town late Friday, kidnapping hundreds of students and marching them into the Zango/Paula Forest. Katsina state authorities reported approximately 320 remained missing Tuesday, the same day the Islamist extremist group Boko Haram claimed responsibility for their abduction. Katsina's governor, Aminu Bello Masari, said 839 boys were enrolled at the school, according to U.S. broadcast network ABC News. It's not clear how many students were at the school at the time of the raid, nor how many eluded the kidnappers. .
