More than 300 schoolboys are still missing after gunmen attacked a secondary school in Kankara, a town in Nigeria’s northwestern Katsina state, authorities said after attackers on motorcycles stormed the all-boys Government Science School late on Friday and engaged security forces in a fierce gun battle, forcing hundreds of students to flee and hide in the surrounding forest. Al Jazeera reports that no group has claimed responsibility for the attack, and the area is far from the usual area of operation of the Boko Haram armed group which began its violent campaign in northeastern Nigeria in 2009 with the goal of imposing its version of strict Islamic law, but the government has insisted that the military will pursue the attackers and rescue the students without any collateral damage.
