There was a bomb explosion today in the Nigerian city of Yola. The bomb was placed in a parking lot and exploded into a nearby marketplace, killing 32 people and injuring 80 more.

So far, no one has claimed the attack, but Boko Haram is thought to be involved. Boko Haram is the same extremist group which kidnapped hundreds of schoolgirls last year; the group wishes to establish a caliphate in Nigeria. It’s just awful, violent, and senseless.
