Saturday's attacks targeted mostly cafes and busy marketplaces. They were the latest in a wave of bloodshed that has swept Iraq since April, killing more than 3,000 people and worsening already strained ties between Iraq's Sunni minority and the Shiite-led government.
The Islamic State of Iraq and the Levant as Iraq's al-Qaida affiliate is known said in a statement on the Internet late yesterday that the bombings were in retaliation for the arrests of hundreds of Muslims by Iraqi security forces.
