The Iranian government has denied a report that President Mahmoud Ahmadinejad was the target of an assassination attempt today. According to a conservative Iranian news website, however, a grenade was thrown at the presidential convoy as it passed through the western city of Hamedan this morning.

The attacker cried “death to the hypocrites” before lobbing the grenade, which landed about 100 yards from the president’s car, KhabarOnline reported. A man was immediately apprehended, according to the website.

Ahmadinejad’s office said there was no bombing attempt but that an onlooker threw a firecracker as the presidential convoy went past.
