Iran’s state news agency reported that President Mahmoud Ahmadinejad won re-election Friday, but his main reformist challenger also confidently claimed victory at a news conference moments earlier. The rival claims came even before the close of polls, which authorities permitted to stay open an extra six hours, until midnight (1930 GMT, 3:30 p.m. EDT), to allow long lines of voters to cast ballots. Official results were not expected until Saturday. Neither the report in the IRNA news agency nor the competing announcement by Former Prime Minister Mir Hossein Mousavi gave details on what their claims were based on. Mousavi said only that he was “definitely the winner of the election” based on “all indications from all over Iran.”
