The death toll from a blast in a market in the northern Iraqi town of Tal Afar rose to 25 on Saturday after four of the six dozen people injured died from their wounds, a security official said. The predominantly ethnic Turkoman town was under an indefinite curfew a day after Friday's bombing, according to the official, who spoke on condition of anonymity because he was not authorized to the speak to the media. The official, who was familiar with the police investigation, said the blast was carried out by a lone Sunni Turkoman suicide bomber from Tal Afar, whose identity was established after forensic tests on his remains. The bomber had been released from detention four months ago under an amnesty passed by parliament earlier this year, he added. Initial reports said a parked car was used in the attack.
