U.N. wants answers on Iranian dissidents missing from Iraq BAGHDAD, Dec. 10 (UPI) -- The Iraqi government is called on to explain what happened to seven members of a dissident Iranian group, a U.N. working group said. The United Nations said seven members of the People's Mujahedin of Iran were missing. They haven't been accounted for since a September attack on the Camp Ashraf compound in Diyala province, which left 52 people dead. "We call upon the government of Iraq to speed up the investigations in order to disclose the fate and whereabouts of the individuals," a U.N. working group on enforced and involuntary disappearances said in a statement Monday. The United Nations said most of the dead at the exile camp suffered gunshot wounds and several bodies were discovered in September with their hands tied behind their backs. The United Nations said a preliminary investigation into the attack suggested Iraqi security forces were responsible. The Iraqi government in 2011 agreed to facilitate the transfer of the dissident community from Diyala to a temporary base in Baghdad. From there, members of the organization are working with the U.N. High Commissioner for Refugees to resettle outside Iraq. The United States last year removed the Iranian dissident group from its list of foreign terrorist organizations.
