The United Nations has renewed criticism of the Iraqi government for refusing to disclose figures on civilian casualties amidst what it calls “a rapidly worsening humanitarian crisis.” The U.N. mission in Iraq says Iraqi officials have turned down repeated requests for numbers on the civilian toll so far this year. No reasons were given. The U.N. did release figures showing at least 3,000 people have been arrested since the launch of the security crackdown on Baghdad two months ago. Overall some 37,000 people are detained in U.S. and Iraqi prisons. Meanwhile, 54 percent of Iraqis are living on less than one dollar a day.
