Iran exile appeal to UN for Iranians detained in Iraq The UN should help free seven Iranian opposition members detained in Iraq following a massacre on 52 of their peers. "I call on the High Commissioner for Human Rights, Navi Pillay, to take the necessary urgent measures to save these hostages. A first step would be a call for their liberation," Maryam Radjavi, head of the People's Mujahedeen of Iran, told a conference at the UN in Geneva, organised by several non-governmental groups.Images and soundbites
