Israel on Wednesday extended the imprisonment of a journalist who has not been charged or tried for any offense, a press freedom watchdog said. Israeli forces detained Nawaf al-Amer, a program coordinator for Quds satellite TV station, in June from his home near Nablus in the northern West Bank. On Wednesday, Israel extended al-Amer's detention for four months, the Palestinian Center for Development and Media Freedoms (MADA) said in a statement. Al-Amer has not been tried or given any reason for his arrest or imprisonment. His wife told MADA that Israel has prevented their sons from visiting their father since his arrest. The center strongly condemned the extension of al-Amer's detention, noting that it stood "in flagrant violation of legal due process under international law." Al-Amer is being held in administrative detention, a practice widely used by Israel against Palestinians under which detainees are held without charge or trial. The Israeli human rights organization B'Tselem says administrative detention "is carried out under the thick cover of privilege, which denies detainees the possibility of mounting a proper defense." MADA urged international organizations to protect Palestinian journalists and to lobby on behalf of those in detention.
