U.S. Central Command has launched an investigation after a drone strike in northwest Syria on Friday may have killed civilians, according to a spokesman for the Command.

The strike, carried out by the International Coalition, targeted a senior al Qaeda leader on a motorcycle on the road to al-Mastuma in Idlib countryside with three missiles, killing him immediately.

Syrian human rights group said that a family of six, including women and children sustained various injuries, as the car they were traveling in was passing near the site of the drone attack.
