The Israeli authorities must end their long-standing attacks on Palestinian human rights defenders (HRDs) and halt the climate of intimidation of HRDs in Israel and the Occupied Palestinian Territories (OPT), Amnesty International said today. Israeli authorities must take immediate steps to provide protection necessary for HRDs in Israel/OPT to carry out their work freely and without fear of attacks and harassment. Attacks and threats against HRDs must be investigated and those responsible must be held to account.
