In the southern city of Karbala, hundreds of Iraqi police and soldiers were on alert as Shiite Muslim pilgrims observed Arba'in, which marks the 40th day after the anniversary of the death of Imam Husayn and his brother Abbas in a battle over the Islamic leadership in the year 680.
Officials in Karbala said more than 3 million pilgrims had come to the city over the past week for the ceremony, which climaxed today.
