Iraq is witnessing its worst eruption of violence in recent years, which raises fears that the country is sliding back to the full-blown civil conflict that peaked in 2006 and 2007, when monthly death toll sometimes exceeded 3,000.
The UN Assistance Mission for Iraq has said that almost 6,000 civilians were killed and over 14,000 others injured in Iraq from January to September this year.
