Palestinians on April 17 commemorated Palestinian Prisoner's Day — first designated in 1974 to mark the 1971 release of the first prisoner exchanged between Israel and Palestine — with nearly 10,000 of their compatriots currently held in Israeli jails, including over 3,500 without charge or trial under administrative detention and 342 children. Rights groups and the Palestinian Authority have condemned a new Israeli law, approved in late March and due to take effect by end of April, that allows military courts to impose the death penalty on Palestinians convicted of deadly attacks against Israelis, a measure the UN human rights chief described as a possible war crime. Since 1967, an estimated one million Palestinians — roughly one in five — have passed through Israeli detention, a scale that critics say reflects a deliberate policy of control rather than security necessity.
