On July 14 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. Forensic Architecture (FA) was commissioned by the Israeli NGO B’Tselem to investigate the circumstances of the boys’ death.
