Gambar, a 60-year-old Shia general, has been put in charge of a security plan that will involve dividing Baghdad into 10 districts patrolled by US troops and forces from Iraq's defence and interior ministries.
 
The force, which is expected to be 60,000 strong, will attempt to root out anti-government fighters and disarm the illegal groups carrying out sectarian attacks on the city's rival Sunni and Shia communities.
