Iran has made its first arrests over a string of deadly pre-election bombings blamed on Iraq-based extremists, vowing that the presidential poll would go ahead without disruption. Up to 10 people were killed in separate attacks in the Arab-dominated city of Ahvaz and the capital Tehran on Sunday, rattling the country in the midst of a fractious and sometimes bruising election campaign. "Some of the perpetrators of the acts have been arrested, others are on the verge of being caught," Information Minister Ali Yusseini told reporters. "They have foreign links," he added, without giving further details.Ahvaz Governor Mohammad Jafar-Sarrahmi pointed the finger at the Iraq-based People's Mujahideen, which is Iran's main armed opposition group, and Baathist supporters of deposed Iraqi president Saddam Hussein. "They want a low turnout [in the election] to show people were not present. They tried satellite television and leaflets, but this did not work. They want to create fear," he said.
