Million Muqtada March

A statement released by al-Sadr's office called on Iraqis of all sects to descend Wednesday on Najaf, site of annual Shiite pilgrimages that attract hundreds of thousands of worshippers.

"The time has come to express your rejections and raise your voices loud against the unjust occupier and enemy of nations and humanity, and against the horrible massacres committed by the occupier against our honorable people," it said.
