A Palestinian woman holds a picture depicting Palestinian detainee Mohammed Allan during a protest in solidarity with Allan, in the West Bank village of Nabi Saleh, near Ramallah August 14, 2015. A Palestinian detainee in the ninth week of his hunger strike fell unconscious at an Israeli hospital on Friday in a case that could test Israel's new force-feeding law. Mohammed Allan, 31, an Islamic Jihad activist, began the strike after his detention without trial in November. Barzilai hospital in Ashkelon said he had been put on a respirator and a saline drip and his condition was stable. The Arabic writing reads, “Save the life of the lawyer and prisoner Mohammed Allan. No for the administrative detention, no for force-feeding”. (Photo by Mohamad Torokman/Reuters)
