Iranian Interior Minister has underlined the ‘highest level’ of cooperation between the two neighboring countries Iran and Iraq during the annual Arbaneen procession visit the holy Iraqi city of Karbala.

Momeni made the remarks in a Friday meeting with Iranian and Iraqi officials in charge of border affairs as millions of Iranian pilgrims make their on-foot journey to the holy Iraqi city of Karbala to attend the million-strong Arba’een procession every day.
 
He hailed the Iraqi interior minister’s “good innovation” to settle six special representatives in six border crossings with the purpose of swift settlement of problems in the border areas.
 
He said the Arba’een march is a manifestation of deep bonds between the Iranian and Iraqi nations.
 
Each year, a large number of Shias travel to Karbala, where the holy shrine of Imam Hussein (AS) is located, to perform mourning rites. Pilgrims, mainly from Iraq and Iran, often journey long distances on foot to reach the holy city.
 
The Arba’een mourning ceremony is one of the world's largest religious gatherings. It commemorates the 40th day after Ashura, the martyrdom anniversary of Imam Hussein (AS).
 
Held annually, Arba’een falls on the 20th day of Safar, the second month of the Islamic lunar calendar. Imam Hussein was martyred in the Battle of Karbala in 680 AD.
