On the 14 July 2018, in Gaza City, in the Occupied Palestinian Territories, two Palestinian teenagers climbed onto the rooftop of the al-Katibah building. A short time later the pair, Luai Kahil and Amir al-Nimrah, were killed by a missile fired from an Israeli aircraft in a 'warning strike'. When the Israeli army shared videos of the attack, the strike that killed the teenagers had been removed. Why did the IDF manipulate their own footage? And what does the incident mean for the 'warning strike' policy?
