Iraq's interior ministry spokesman says a suicide bomber has blown himself up among Shiite pilgrims in northern Baghdad, the deadliest in a series of attacks that have killed 41 people.
Interior Ministry spokesman Saad Maan says the bomber struck a pedestrian checkpoint for pilgrims in the largely Sunni neighborhood of Azamiyah. He says at least 56 people also were wounded in the attack.
Police and hospital officials also say a bomb exploded in the religiously mixed Baghdad neighborhood of Baiyaa, killing three people and wounding 13 wounded.
The officials spoke on condition of anonymity because they were not authorized to speak to journalists.
The bombings followed earlier attacks day that killed 21 other people.
