Iraq is now in a civil war.

Thirty thousand Iraqis have died there in the past three years, more than in many other conflicts widely recognized as civil wars. The number of internal refugees, mostly Sunni victims of ethnic cleansing, has exploded over the past few months, and now exceeds a quarter of a million people. (The Iraqi government says 240,000, but this doesn't include Iraqis who have fled abroad or who may not have registered their move with the government.)

The number of attacks on Shiite mosques increases every week: there have been 69 such attacks since February, compared with 80 in the previous two and a half years. And the war is being fought on gruesome new fronts. CBS News's Lara Logan has filed astonishing reports on the Health Ministry, which is run by supporters of radical cleric Moqtada al-Sadr.

According to Logan, hospitals in Baghdad and Karbala are systematically killing Sunni patients and then dumping their bodies in mass graves.
