Iraq violence, including attacks on Shiites, kills 18

A series of coordinated bombings targeting Shiite pilgrims ahead of major commemoration rituals were the deadliest in attacks across north and west Iraq that killed 18 people today.
The bloodshed is the latest in a months-long surge in violence that authorities have so far failed to stem despite several operations against insurgents, and have forced Prime Minister Nuri al-Maliki to appeal for help from Washington in combating militancy.
Today's violence came on the eve of annual ceremonies marking the anniversary of the death of a key figure in Shiite Islam, a period during which Sunni militants typically step up attacks on Shiites, whom they regard as apostates.

The deadliest unrest was on the outskirts of Baquba, which lies north of Baghdad and is one of Iraq's most violent areas, with three coordinating bombings targeting a gathering of Shiite pilgrims marking Ashura.
The blasts killed at least eight people and wounded 25, security and medical officials said.
In the days leading up to the climax of Ashura, which this year falls tomorrow, Shiite Muslims often set up procession tents where food is distributed to passers-by and pilgrims can gather.

Violence elsewhere in Iraq today killed 10 people and police also gunned down three militants, officials said.
East of the predominantly Sunni Arab town of Tikrit, a suicide bomber detonated a vehicle rigged with explosives at a police checkpoint, killing six people -- three policemen and three civilians.

And near the former insurgent bastion of Fallujah, two bombs targeting the homes of policemen, followed by a third that went off as onlookers gathered at the scene, killed four people and wounded a dozen more overall.
A police raid in the Jazeera desert region in northwest Iraq, meanwhile, led to three militants being killed. Four policemen were also wounded in the operation.
Today's deaths were the latest in Iraq's worst violence since 2008, with more than 5,600 people killed this year despite tightened security measures and a swathe of operations against militants.
Maliki has called for help from the United States in the form of intelligence-sharing and the delivery of new weapons systems in an effort to deal with the unrest.
