Two suicide bombers struck in a Sunni Arab district of Baghdad on Monday, killing at least 14 people including the leader of a U.S.-backed neighbourhood security patrol, police said.
The strikes were the latest in an apparent stepped-up campaign of suicide bombings that has seen major attacks nearly every day for the past two weeks, even as overall levels of violence in Iraq have fallen.
The U.S. military blamed al Qaeda and said the attacks provided "perhaps the clearest proof of the nature of this enemy that will destroy the very people and neighbourhoods of whom it claims to protect".
After nightfall, gunmen in five cars kidnapped between eight and 10 neighbourhood patrol volunteers in the northern Shaab district of Baghdad, police said. The volunteers had been manning a vehicle checkpoint.
Earlier, chanting mourners carried the bodies of Colonel Riyadh al-Samarrai and some of his slain bodyguards through the streets of the mainly Sunni Arab Adhamiya neighbourhood, where the colonel led volunteer patrols in the pay of U.S. forces.
"The martyrdom of the colonel is an inspiration to us now. All of us will become Colonel Riyadhs," said Abu Firas, another senior member of the "awakening" movement in the area, the Iraqi name for Sunni Arab tribes that have turned against al Qaeda.
Three separate police and security sources confirmed the death toll and said about 20 people were wounded. Baghdad security spokesman Brigadier-General Qassim Moussawi told Iraqiya state television six people were killed and 26 wounded.
One of the bombers detonated an explosive vest, the other struck with a car bomb.
