"Iran unblocked Facebook just days after the popular social networking website was banned, an Iranian news agency reported Tuesday.
"The Iranian Labor News Agency, or ILNA, said the site is now accessible to ordinary Web surfers. The rescinding of the ban came a day after Iranian President Mahmoud Ahmadinejad denied he was behind the decision to block the site, which has been used by his challengers to rally supporters for next month's presidential election.
"Reformist challenger Mir-Hossein Mousavi, a former prime minister, was using Facebook to generate buzz for his campaign. According to the tersely worded ILNA report, the site has been blocked and unblocked numerous times over the last few days."
