US troops seal off the Valley of Peace cemetery in the Shiite holy city of Najaf 28 August 2004. The cemetery -- the largest in the world -- was the scene of intense fighting in recent months between US troops and fighters loyal to radical Shiite cleric Moqtada Sadr. From the most luxurious mausoleums with coloured ceramic domes to the most modest and anonymous mud tombs, every square metre (yard) bears the scars of war. The vast expanse housing an estimated five million graves was fought over by the Mehdi Army and US troops as a rear base for the confrontation around the militia's stronghold in the Imam Ali mausoleum.
