The assault on Baquba began Monday with an attack launched against the Al Wahda police state on the city's western edge.
Iraqi security forces continued to clash with the insurgents into Tuesday. Baquba officials reported one ISF member, nine militants, and 44 prisoners were killed in the assault. The prisoners were killed when ISIS militants threw a hand grenade into the local prison.
