A suicide bomber– dressed in a school uniform and apparently carrying explosives in a student rucksack– killed at least 48 people at a boys high school in northeastern Nigeria Monday.
The militant group Boko Haram is believed to have carried out the attack, police told the BBC. The terror group—whose name roughly translates to “Western education is forbidden”– has regularly targeted schools during a deadly five-year insurgency aimed at establishing an Islamic state. The extremists have initiated violent attacks to prevent children from going to school, believing girls should not attend school and boys should only receive an Islamic education.
