Iran denies reports of attack on Ahmadinejad

Iran denied reports that President Mahmoud Ahmadinejad's convoy sustained a grenade attack on Wednesday, according to state-run Press TV.

"It wouldn't be surprising if the president's office tries to play this down. It's very difficult to say who could be behind it," IHS Global insight Middle East analyst Gala Riani told Reuters.  Riani added that the president often travels outside Tehran, but that at most, "There have been occasions when people have thrown things at him or heckled him but that has been it."
