Palestinians take part in a protest against the death of a Palestinian detainee in an Israeli jail, in front of the headquarters of the United Nations in Gaza City February 25, 2013. Palestinian officials on Saturday demanded an international investigation into the death of a Palestinian detainee who died in an Israeli jail hours earlier. A spokeswoman for Israel's Prison Authority said that the detainee, 30-year-old Arafat Jaradat, had apparently died of cardiac arrest. An emergency service team had tried to resuscitate him but failed, she said. Photo by Yasser Qudeh
