Iranian officials say tens of thousands of Iranian police and security officers will be on the streets Friday to ensure the country's presidential election runs smoothly. Campaigning for Iran's June 17 presidential election ended today. Political analysts say Hashemi Rafsanjani, considered to be a moderate cleric, is leading the group of seven candidates in the race. The head of Tehran's police force, Brigadier General Morteza Talai, said some 20,000 police will be deployed in the city from today until Saturday. He said about 10,000 police officers will be in charge of the security of polling stations. Talai said also that no car would be allowed to park within 50 meters of any polling station. Interior Minister Abdolvahed Moussavi-Lari said that there will be police officers stationed at each of the polling stations across Iran. The run-up to the election has been disturbed by bomb attacks at the weekend in the ethnic Arab-dominated city of Ahvaz, and in Tehran, that killed up to 10 people. A mlitant Arab group in southwest Iran has claimed responsibility for the bombings. U.S. President George W. Bush today said that Iran's upcoming elections ignore the basic requirements of democracy. He also said Iran is "ruled by men who suppress liberty at home and spread terror across the world."
