Iraqi police chief killed
A roadside bomb in Iraq killed the provincial police chief and two guards, Sunday.
The roadside bomb struck a convoy that was carrying the police chief and two guards of a province south of Baghdad.
This is the most recent of a series of assassinations against provincial in areas south of the capital.
It may be due to the militias trying obtain control of the area, authorities said.
Police are enforcing an indefinite curfew in many provinces near the scene of the bombing and security is increased.
