Iran is a transit route for pilgrims from the eastern neighbors, Pakistan and Afghanistan, to participate in the annual pilgrimage of Arbaeen in Iraq.
Every year, over 20 million pilgrims, mainly Shia Muslims, attend the event, which marks the 40th day after the martyrdom anniversary of the third Shia Imam, Hussein ibn Ali, and his companions in 680 AD on the plains of Karbala.
