Shiite pilgrims march through Baghdad surrounded by security

Amid chilly temperatures and heavy security, thousands of black-clad pilgrims from across Iraq marched Thursday in the annual procession in marking the death of a Shiite saint.
Pilgrims traditionally travel on foot to the shrine and burial site of Imam Moussa al-Kadhim, the seventh of 12 Shiite imams who died in a Baghdad prison in the eighth century. The procession leads to the site in the northern Baghdad neighborhood of Kadimiyah. Participants wear black, with some carrying out self-flagellation to publicly express their mourning.
Tents were pitched along the kilometers of road that the pilgrims were walking Thursday, handing out food and water free of charge. Thousands of Iraqi security forces were deployed across the city to ensure the safety of the pilgrims, while some roads and bridges were closed to vehicles to allow pedestrian traffic only.
