Unprecedented dissent gripped Iran following a disputed victory for Iranian President Mahmoud Ahmadinejad in the June 12 presidential election. Tehran has since hauled in a number of dissenters that it claims sparked anti-government violence.

Iranian Parliamentary Speaker Ali Larijani blasted U.S. and French officials for interfering in Iranian affairs, the Islamic Republic of Iran Broadcasting network reports.
"It is a sample of your position in today's world and your failure is originated from ailing diplomacy of America and general hate towards them," said Larijani.
In his speech before the Iranian Parliament, Larijani said it was time for Western powers to assess the political consequences of their moves.
