(Reuters) Suspected Islamist gunmen killed 27 students and a teacher in a boarding school in the northeast Nigerian town of Potiskum on Saturday, a police source said.
The attack was the deadliest of at least three on schools since the military launched an offensive in May to try to crush Islamist insurgent group Boko Haram, whose nickname translates as "Western education is sinful" in the northern Hausa language.
The attackers set fire to buildings and shot pupils as they tried to flee, the source told Reuters by email. A hospital was treating several of the students for burns, he added.
