On March 16, explosions rocked a mosque in Maiduguri, Nigeria. A woman detonated a bomb strapped to her chest inside the mosque minutes after the morning prayer. Dozens of people attempted to escape the building, and a second woman detonated another bomb outside to catch the fleeing worshipers. Unfortunately, the blasts claimed the lives of 22 people and injured another 18 people. Nobody claimed responsibility for the attack as emergency responders hit the scene.

Of course, Maiduguri is the birthplace of one notable extremist group: Boko Haram. Boko Haram has risen to prominence in recent years as a ruthless terrorist organization. Thousands of people have been killed by the group’s forces, and millions have been sent fleeing from their homes because of such actions. From 2009 to present day, Nigeria has seen terrorist attack after terrorist attack with increasing frequency. Brussels would experience a terrorist attack of its own only six days after the Maiduguri event.
