The U.S. has finished investigating an anti-ISIS airstrike in March that killed over 100 civilians.
A report from the Pentagon says an airstrike targeting snipers on a roof accidentally triggered secondary explosives planted by ISIS. That explosion caused the entire building to collapse, killing civilians inside.
The U.S. says 105 civilians died in the strike, and another 36 people are still unaccounted for. That's lower than the initial estimates of up to 200 civilians killed in the strike.
