Shia Muslims Walk To Holy City Of Karbala To Mark Arbaeen

BAGHDAD, IRAQ - FEBRUARY 12: A Shia Muslim boy and girl carry a religioius flag as they walk toward the holy city of Karbala, 150 km away, during the festival of Arbaeen February 12, 2009 in Baghdad, Iraq. Arbaeen marks 40 days after the Ashoura holiday which commemorates the death in battle of Imam Ali in 680, which began the schism between Sunni and Shia Muslims that endures to this day. Millions of Shia will walk for up to five days to reach Karbala by Monday. (Photo by Chris Hondros/Getty Images)
