Arbaeen, which means 40 in Arabic, is one of the world’s biggest religious gatherings and a major event for Shia Muslims, who are the majority in Iraq and Iran.

Pilgrims freely express their suffering, weeping and wailing in memory of Hussein, who was killed in 680 during a battle in Karbala with the Umayyad caliph Yazid.
This year, the events have included prominent displays of Palestinian flags by pilgrims amid the war in Gaza.
“The total number of Arbaeen pilgrims… reached 21,480,525,” the institution that manages the Abbas mausoleum and is responsible for the count said.
Among them were about 3.5 million Iranian pilgrims, according to official figures reported in Tehran.

Israel has killed more than 40,000 Palestinians in Gaza since October. An estimated 1,139 people were killed during a Hamas-led attack on southern Israel on October 7.
The Arbaeen celebrations, which always take place amid tight security, drew about 22 million pilgrims last year, according to official figures. Iran provided the most foreign visitors, with 4 million.
