Millions of Shia Muslims have taken part in one of the biggest marches in the world, as they travel through Iraq in celebration of a famous Muslim martyr.
The marchers made their way to the city of Karbala, 62 miles south west of Baghdad, on Sunday and Monday for the holy day of Arbaeen, which marks the end of a 40-day mourning period following Ashura, the religious ritual that commemorates the death of the Prophet Mohammad's grandson Imam Hussein in 680 AD.
Large crowds visit the shrines of Imam Hussein and his half-brother Abbas in Karbala, where they were killed in a revolt against the Umayyad ruler Yazeed in the 7th century AD when they refused to pledge allegiance to Yazeed's Umayyad caliphate.
Nusayyef al-Khattabi, who heads the Karbala provincial council, said he expected the total number of visitors over several days to range “between 17 million and 20 million”. Among them are an estimated three million foreigners, the majority Iranians who started crossing the border days ago.
Many choose to make the journey on foot, despite travelling near Isis-controlled areas in the country and the extremist group having made frequent deadly attacks on the pilgrimage. [MORE]
