Iraq is witnessing its worst eruption of violence in recent years, which raises fears that the country is sliding back to a full-blown civil conflict that peaked in 2006 and 2007, when monthly death toll sometimes exceeded 3,000. The UN Assistance Mission for Iraq recently reported that over 1,000 Iraqis were killed and more than 2,300 wounded in acts of terrorism and violence in July, the deadliest month in more than five years.
