This memorandum sets out some of Amnesty International’s concerns about the use of lethal force by the Israeli army, Border Police, Israel Police and private security guards over the period from 22 September 2015 until 6 September 2016. It provides details of 20 cases of evidently unlawful killings of Palestinians, including 15 possible extrajudicial executions, carried out by Israeli forces, and seeks clarification about the investigations carried out by the Israeli authorities into these killings and the policies governing the use of lethal force by Israeli forces.
