Nigeria Probes Student Killings

Nigeria's authorities are investigating the killings of at least 26 people in an attack on a college hostel in the north-eastern town of Mubi. Most victims were students called out by name by the gunmen, police said. A resident said the attackers went from door-to-door, shooting or stabbing. It is unclear who is responsible. Monday night's attack came days after dozens of people with suspected links to the Boko Haram militant group were arrested in the town. However, officials have not ruled out a recent student union election dispute as being the trigger for the violence at Federal Polytechnic Mubi. If that proves to be the case it will shock many Nigerians, as violence amongst students has never reached this level before, the BBC's Will Ross in Lagos reports. A curfew has been in force between 15:00 (14:00 GMT) on Tuesday and 06:00 (05:00 GMT). The college has been closed and some students have fled the town.
