Iranians find joy in serving pilgrims on road to Karbala

Volunteers offer food to fellow pilgrims as thousands of Iranian Shiite Muslims make their way to the Mehran border point between Iran and Iraq, heading toward the central Iraqi shrine city of Karbala ahead of the Arbaeen religious festival. Arbaeen, which marks the 40th day after Ashura, commemorates the seventh century killing of Prophet Mohammed's grandson Imam Hussein.
