Iraqi security officials say a suicide bomber killed at least 30 people and wounded more than 60 Wednesday after detonating an explosives-filled belt near a crowd of Shi'ite pilgrims.
Officials say the attack took place in Adhamiyah, a Sunni district of Baghdad. Investigators say at least five other people were killed in separate bombings in the city, including two other pilgrims.
The attacks took place in spite of heavy security in the Iraqi capital, where tens of thousands of worshippers had gathered for ceremonies marking the death of Imam Moussa al-Kadhim, the seventh of 12 revered Imams in Shi'ite Islam.
Police say a series of attacks killed at least six Shi'ite pilgrims in Baghdad Tuesday.
Wednesday's suicide bombing took place near a bridge where about 1,000 Shi'ite pilgrims died in a stampede five years ago, after they had gathered for the same ceremony.
