TEHRAN, IRAN: Thousands of mourners have attended funeral services in Iran for pilgrims killed in a stampede during last month's hajj pilgrimage in Saudi Arabia. A ceremony at Tehran University on Sunday was one of several held for dozens of victims whose remains were flown back to Iran the day before. Another 114 bodies arrived Sunday. Iran has blamed Saudi authorities for the disaster, which heightened tensions between the two regional rivals. Mourners at the Tehran ceremony chanted 'death to Al-Saud,' referring to Saudi Arabia's ruling family. Saudi authorities say 769 pilgrims died in the stampede near Mecca in the worst disaster to strike the annual pilgrimage in a quarter-century. Iran appears to have lost the largest number of pilgrims, with 464 dead.
