TEHRAN, Iran -- The Iranian government has blocked access to the social networking site Facebook amid political jockeying for the June 12 presidential elections, according to the semi-official Iranian Labour News Agency.

Opponents of Mahmoud Ahmadinejad like Mir Hossein Mousavi are using technology to reach voters.

Reformist candidate Mir Hossein Mousavi -- a former prime minister considered a threat to current hardline President Mahmoud Ahmadinejad -- created a Facebook page for his campaign that has more than 5,000 supporters on the site.

Those attempting to visit Facebook received a message in Farsi saying, "Access to this site is not possible," according to CNN personnel in Tehran.

ILNA reported the Masadiq Committee, made up of representatives from Iran's intelligence ministry, judiciary and others had ordered the action.

After a few hours, the blockage was lifted, but was then reinstated, ILNA said. No reason was given for the block.
