BAGHDAD: Throngs of Shiites converged on a shrine in north Baghdad Saturday for annual commemoration rituals under heavy security after a string of deadly attacks in the Iraqi capital.
Much of the city was on lockdown for the climax of the rites to mark the death of a revered figure in Shiite Islam, with Baghdad's security forces looking to deter Sunni militant groups which often target Iraq's majority community.
Several major roads were closed off and a wide variety of vehicles barred from the streets, as security forces also relied on aerial cover and sniffer dogs.
Organisers say millions of pilgrims are expected to visit the shrine in the Kadhimiyah neighbourhood of north Baghdad between Saturday and Sunday, when the commemoration rituals are to climax, though the figure could not be independently verified.
For days worshippers from across Baghdad, and the rest of the country, have been walking to Kadhimiyah, site of a shrine dedicated to Imam Musa Kadhim, the seventh of 12 revered imams in Shiite Islam, who died in 799 AD.
Sunni militants regard Shiites as apostates and, as in previous years, multiple attacks have targeted worshippers in the run-up to the Imam Kadhim commemorations.
Three bombings in the capital, including two carried out by suicide attackers, on May 22 killed 21 people, while mortar fire on Friday struck a district adjacent to Kadhimiyah, killing three more.
Violence has surged in the past year to its highest level since 2008, while anti-government fighters also control an entire city a short drive from Baghdad and parts of another.
The authorities have trumpeted security operations against militants, and blame external factors such as the civil war in neighbouring Syria for the surge in violence.
Analysts and diplomats, however, say the Shiite-led government must do more to reach out to disgruntled minority Sunnis and undermine support for militancy.
