Sadr city residents have buried eight pilgrims killed in Sunday's car bombing. Residents of the Shi'ite district of Sadr City mourned on Monday (March 12) eight Shi'ite pilgrims who were killed in a suicide car attack were travelling in a lorry in Baghdad's central Karrada district on Sunday. The attack in the predominantly Shi'ite district of Karrada killed 19 Shi'ite pilgrims and wounded 25 people, according to police. Bereaved relatives wept and beat their chests as they marched in a funeral procession in the streets of the district as cars and minibuses carried coffins draped in the Iraqi flags. The pilgrims were returning from the holy city of Kerbala, south of Baghdad, where nearly a million gathered over the weekend for the Arbain ritual, the 40th and final day of mourning for Imam Hussein, grandson of Mohammad. Chanting "We will never forget Hussein", in a reference to Prophet Mohammad's grandson who was killed in a battle in kerbala in 680, mourners carried large black banners consoling Shi'ite cleric Moqtada al-Sadr on the death of the pilgrims. Suspected Sunni Arab insurgents have killed scores of Shi'ite pilgrims in recent days as part of a campaign officials say is meant to incite a sectarian civil war in Iraq. Mounting sectarian violence between Sunnis and majority Shi'ite Muslims has become a major issue since the bombing of a Shi'ite shrine a year ago. Since the U.S invasion in 2003 tens of thousands have been killed and some 2 million have fled to neighbouring countries.
