I believe many more people have been hurt since this was reported.

Bomb attacks at crowded markets in central Baghdad killed at least 76 people on Monday as Iraqis marked the first anniversary of a Shi'ite shrine bombing that pitched the country to the brink of civil war.

The blasts came a day after Shi'ite Prime Minister Nuri al-Maliki said Iraqi security forces would step up their deployment in Baghdad under a U.S.-backed offensive against militants.

In the deadliest attack, at least 71 people were killed and 164 wounded in the popular Shorja wholesale market.
