Two bombings in Baghdad on Thursday killed seven people bringing the death toll from attacks against Shiite plgrims over the past three days to at least 60, security sources said.
A roadside bomb in the central Bab al-Muazam neighbourhood killed four people and wounded 46, while a second bomb in the southeastern Mashtal district killed three and wounded 31, a security official said.
Attacks since Tuesday on the tens of thousands of Shiite faithful taking part in the pilgrimage to the Musa Kadhim shrine have now wounded more than 300 people since Tuesday, security sources.
The Shiite majority in Iraq have been a main target of Sunni Arab armed groups since the US-led invasion of 2003 toppled now executed dictator Saddam Hussein's Sunni-dominated regime.
Pilgrimages to the Shiite holy places have been repeatedly hit.
