But the most controversial drone strike took place on Oct. 14, 2011, when 16-year-old Abdulrahman was killed by U.S. forces.

Family of the Denver-born teenager say he had no ties to terrorist organizations and was unjustly targeted because of his father.

Nassar al-Awlaki, grandfather of Abdulrahman and father to Anwar, said he tried to protect his grandson as Anwar al-Awlaki’s profile grew.

In December, Nassar al-Awlaki told CNN, “In Anwar it was expected because he was under targeted killing, but how in the world they will go and kill Abdulrahman. Small boy, U.S. citizen from Denver, Colorado.”

Nassar al-Awlaki said his grandson snuck out of their Yemen home one night, leaving a note for his mother saying he would return in a few days. The boy never returned, killed instead while eating at an outdoor restaurant.
