Palestinian men and boys between the ages of 12 and 70 are stripped, cuffed, blindfolded and then loaded onto the backs of trucks to be taken for interrogation. Some have numbers written on their arms. Hundreds detained in Gaza have been transported to the desert prison of Ketziot, near the border with Egypt. Others have probably been taken to nearby military bases. Some men who were taken prisoner in Beit Lahiya were stripped and transported to fenced-off camps where for days they were tied up, beaten and tortured. Others have disappeared. The IDF has subsequently said that between 85 and 90 per cent of these detainees were civilians. Israeli forces have repeatedly raided UN schools and detained any men found inside. The Office of the United Nations High Commissioner for Human Rights documented an incident on 19 December when the Israeli army surrounded and then entered a building in the Remal neighbourhood of Gaza City. ‘The IDF allegedly separated the men from the women and children, and then shot and killed at least eleven of the men, mostly aged in their late twenties and early thirties, in front of their family members.’
