(New York Times) – When the girls appeared on the screen, parents in the small room at the government compound here dissolved into tears. The militants released their video to news organizations on Monday,providing the first glimpse of the girls in what has become a global search effort, spurred by a grass-roots outcry on two sides of the Atlantic. The girls, some 276 of whom remain missing, are now bargaining chips for Boko Haram, which is demanding that the Nigerian government release its imprisoned members in exchange for the kidnapped students.
