On September 17, 2014 an armed group attacked a teacher training college in Nigeria, killing at least fifteen people and injuring thirty-four. Two suicide bombers detonated their devices in a full lecture hall, while other attackers threw explosives and fired at those who attempted to escape.Officials have attributed this attack to Nigerian separatist group Boko Haram, although the group has not publically taken responsibility. 
Scholars at Risk is concerned about violent attacks on higher education institutions.  Such attacks threaten the lives and well-being of members of higher education communities; undermine higher education functions and values, including autonomy and academic freedom; and impair the ability of higher education to serve its public mission.  State authorities have a responsibility to ensure the security of academic communities, to prevent future attacks, and to hold perpetrators of violent attacks accountable.
