Two bombs have killed at least 39 people and injured over 100 more in the central Pakistani city of Multan. The dawn explosions on Thursday ripped through a crowd of about a thousand people who had gathered to mark the first anniversary of the assassination of Sunni activist leader Azam Tariq. Witnesses said the suspected sectarian attack, which left Multan's main Rashidabad Square littered with body parts and blood stains, triggered a stampede which also left several people dead. The chief medical officer of the city's main hospital, Dr Imran Rafiq, said the toll had reached 39, with many of the wounded blaming the attack on Shia Muslim extremists. "This attack is carried out by Shia," said Sunni community leader Muhammad Ludhianvi. "They are being funded and sponsored by the government of Iran to kill Sunnis in Pakistan." **Official reaction*** Police believe at least one blast was a car bomb. "The bomb was probably planted in a car and as soon as the meeting was over it was detonated with a remote control or a timer," said district police chief Sikandar Hayat. Pakistani Information Minister Shaikh Rashid condemned the attack. "It is an act of brutal terrorism aimed at creating instability in the country," he said. **PHOTO CAPTION*** Volunteers carry the body of a bomb blast victim on a stretcher after an attack on Muslims in Pakistan's Multan city.
