"A CONFIDENTIAL REPORT by Israeli military police investigators seen by The Intercept explains how a tragic series of mistakes by air force, naval, and intelligence officers led to an airstrike in which four Palestinian boys playing on a beach in Gaza in 2014 were killed by missiles launched from an armed drone.

Testimony from the officers involved in the attack, which has been concealed from the public until now, confirms for the first time that the children — four cousins ages 10 and 11 — were pursued and killed by drone operators who somehow mistook them, in broad daylight, for Hamas militants."
