French-Palestinian lawyer Salah Hammouri has been issued a three-month administrative detention order. He is a field researcher for Palestinian NGO Addameer and has been held without charge or trial since 7 March. Since 2002, Israeli authorities have persistently harassed Salah Hammouri, who has been detained several times. He is also at risk of deportation as Israel’s Ministry of Interior has taken action to revoke his residency status in East Jerusalem. The Israeli authorities must release Salah Hammouri immediately and ensure that he is allowed to keep his residency status in Jerusalem and continue with his human rights work without fear of reprisals.
