Iraq's defense minister says tens of thousands of security forces will ring Baghdad next week "like a bracelet that surrounds the hand."
The deployment is intended to stop a wave of attacks that has killed hundreds of people in the last month.
The minister says 40-thousand Iraqi police and soldiers will form "a strong and safe cordon" around the capital.
The interior minister says there will be 675 stationary checkpoints, plus mobile checkpoints to deter attackers where violence is frequent.
He says "security is for all the citizens, not just the government."
In a Baghdad news conference, the officials announced other new
measures in how police and emergency workers will operate in the city.
