Iran denies attempted attack on President Ahmadinejad
Iranian officials have denied that President Mahmoud Ahmadinejad was targeted in an assassination attempt.
A conservative Iranian website had said an explosive device was thrown at his convoy in the western city of Hamedan, where he was to deliver a speech, but later removed the report from its site.
State-run Press TV said "no such attack had happened", and officials said the blast was caused by a firework. Mr Ahmadinejad went ahead with his speech at a football stadium.
