The cemetery in the Iraqi holy city of Najaf is one of the largest in the world, and is the coveted final resting place for Shiite Muslims from around the globe.
The site is considered auspicious, because it is next to the tomb of Imam Ali, the Prophet Muhammad's son-in-law and the man Shiites believe to be his true heir.
This city of the dead, called the Valley of Peace, holds the remains of millions.
