As Iran witnesses an unprecedented turnout in its closely-fought presidential election, the polling time is extended to accommodate the massive lines of voters. The Interior Ministry announced that the polling time has been extended to 9 p.m. local time. Our correspondent Gisoo Misha Ahmadi who is stationed at the ministry reported that polling stations have been ordered to remain open until further notice due to the massive electoral turnout. Tens of millions of Iranians have crowded to the polls to take part in the election in which the incumbent President Mahmoud Ahmadinejad seeks a second term in office while facing a strong challenge from former prime minister Mir-Hossein Moussavi. After weeks of intense campaigns, turnout appears to be extraordinarily high, with polling stations packed all day. Interior Minister Sadeq Mahsouli said that the turnout would be above 70 percent -- a new record. Kamran Daneshjoo, the head of the country's electoral committee, had earlier promised to put in place a strategy to ensure "maximum participation" from the 46.2 million eligible -- aged 18 and above -- voters. Two-time parliament Speaker Mehdi Karroubi (1989-1992 and 2000-2004) and Expediency Council Secretary Mohsen Rezaei are also battling for office in the crucial election. If no candidate gets absolute majority of votes in the first round, the two front-runners will face a run-off vote on June 19 Show Less >>
