Shi'ite Muslims cut their heads with knives during an Ashura procession in Basra, 550 km (340 miles) south of Baghdad, January 30, 2007. An estimated 2 million black-clad Shi'ite pilgrims swamped the Iraqi holy city of Kerbala on Monday for an extraordinary display of grief over the death of the Prophet Mohammad's grandson there 1,300 years ago.
