Muslims from all across the world including Iran have been marching toward the Iraqi holy city of Karbala to perform the rituals of Arba’een.
According to officials, as many as two million Iranians have headed to Karbala. Imam Hussein is a respected figure not only among Shias but also Sunni Muslims. Even some Christians join the march to Karbala.
This year, the Mehran border crossing with Iraq, which is used by Iranians, had to be temporarily shut by Iraqi authorities due to the overwhelming influx of pilgrims.
The occasion unifies Muslims in the face of attempts to create divergence, animosity and misunderstanding among them.
There are also alot of people that in the especial day flock to Mashhad, Iran's holy city, to the shrine of Imam Reza, the eighth Imam of Shias, , northeastern province of Khorasan Razavi.
