Held annually on April 17, Palestinian Prisoner’s Day is a national day dedicated to the freedom of Palestinians held in Israeli prisons and support for their rights. This year, Palestinian Prisoner’s Day – which is typically marked by rallies and other events – comes as Israel continues to crack down on Palestinians in Gaza and the occupied West Bank, including occupied East Jerusalem, amid its war on the Gaza Strip. According to Addameer, a Palestinian prisoner support and advocacy group, just less than 10,000 Palestinians were held in Israeli prisons as of April 14. That includes 3,498 Palestinians held without charge or trial under what’s known as “administrative detention”. Rights groups have long denounced Israel’s treatment of Palestinians in Israeli jails but noted that abuses have worsened since the war on Gaza began.
