In the shadow of the war raging in Gaza, record numbers of Palestinian detainees are filling Israeli prisons, where they face "systemic abuse" and torture, rights advocates warn, calling for international action.Members of several Israeli NGOs travelled to Geneva this week to raise concerns before the United Nations about a major "crisis" inside the country's prisons. "We are extremely, extremely concerned," said Tal Steiner, the executive director of the Public Committee Against Torture in Israel (PCATI)."What we're looking at is a crisis," she told AFP.
