According to Amnesty International, around 100 people may have been killed in the airstrike in Yobe state in Nigeria's violence-ridden northeast.
The target of the attack was a "logistics center" belonging to the jihadist group ISWAP in the area, according to a previous statement from the military. But something appears to have gone wrong in the planning, leading to the deaths of many civilians.
