UN Says Innocent Pakistanis Killed By Drone Strikes

Adult men often killed after being mistaken for the intended target

(CNN) — A group of farmers is on its way to tend to crops. Suddenly, a missile slams into its midst, thrusting shrapnel in all directions.

A CIA drone, flying so high that the farmers can't see it, has killed most of them. None of them were militants.

It's a common scenario, a United Nations human rights researcher said Friday in a statement on drone strikes in Pakistan's tribal region of North Waziristan.
