If this isn't civil war, what is?

From the Washington Post:

BAGHDAD, Oct. 15 -- Militias allied with Iraq's Shiite-led government roamed roads north of Baghdad, seeking out and attacking Sunni Arab targets Sunday, police and hospital officials said. The violence raised to at least 80 the number of people killed in retaliatory strikes between a Shiite city and a Sunni town separated only by the Tigris River.

The wave of killings around the Shiite city of Balad was the bloodiest in a surge of violence that has claimed at least 110 lives in Iraq since Saturday. The victims included 12 people who were killed in coordinated suicide bombings in the strategic northern oil city of Kirkuk.
