My latest article breaksdown the security situation in Diyala. That was one of the first places the insurgency began rebuilding itself in 2012. That quickly brought in militias, one of the first places they deployed outside of Baghdad in 2013.

Since then the security forces and militias have launched security operation after operation often in the same areas because it doesn't have the forces to hold any area.

Province has also seen sectarian killings by militias just like what happened from 2005-2008. Read more here.
