Counterterror strikes have been eclipsed by the horrors of the Saudi-led war in Yemen, but U.S. drones are killing many people who have no Al Qaeda ties.

In an interview with The Intercept, a Yemeni man whose relatives were killed in a US drone strike in April says “it was a shock no human can accept."

Abdulmalik Amer, an ambulance driver in northern Yemen known for traveling dangerous routes others were too afraid to drive, was killed by an airstrike while responding to an emergency call.

Amid Yemen's civil war, details surrounding the death of American contractor John Hamen, and the fate of other U.S. citizens held prisoner in the country, remain unknown.
