Over 3800 Iraqi's have died during the first three months of 2006 in targeted killings. That is more than at any other time since the invasion of Iraq back in 2003. The morgue in Iraq on an average day, handles about 40 bodies. That itself is more than an average day since the war started.
There has been a spike in sectarian violence since the Golden mosque was blown up in March. Sunni against Shia violence is responsible for at least 90% of the killings since February.
Most of the dead bodies found have either been strangled, electrocuted, stabbed, garroted, hanged, or hogtied and shot execution style.
Those who say that Iraq is not in a civil war, are just fooling themselves.
