Three suicide bombers and a roadside bomb struck Shiite pilgrims taking part in a massive religious procession in Baghdad on Monday, killing at least 26 people and wounding 85, police said. The attacks occurred in quick succession as tens of thousands of Shiite worshippers streamed toward a shrine in northern Baghdad for an annual event marking the death of an eighth century saint, which climaxes on Tuesday. Police said there were indications to suggest the suicide bombers were women. At least two children were among the dead, said police officials, who spoke on condition of anonymity because they were not authorized to speak to the media. The attacks took place in the mainly Shiite Karradah district, which is several miles away from the site of the pilgrimage in Kazimiyah, northern Baghdad.
