Shiite Muslims prepare for Ashura in Tehran

A vendor sells imaginary pictures of Imam Hussein for Ashura in downtown Tehran, Iran on January 10, 2007. Ashura is the peak of ten days of mourning during the Islamic month of Muharram, the first month of the lunar calendar, when Shiite Muslims mourn the slaughter of Imam Hussein 1366 years ago in what is now Karbala in southern Iraq.
