Islamist militants murder dozens of students in Nigeria

At least 58 students were murdered at a Nigerian agricultural college by suspected Boko Haram militants, who set a locked dormitory ablaze and cut the throats of those who tried to escape. In the last month, more than 300 people in northeastern Nigeria have been killed by the militant group. J. Peter Pham of the Atlantic Council joins Judy Woodruff to discuss instability in Nigeria.
