Iran`s President Mahmoud Ahmadinejad has survived an attack on his convoy in western Iran, media reports from the region say, according to BBC.

The reports say a device was thrown at the convoy in the city of Hamedan, where he was to deliver a speech.

Mr Ahmadinejad was unhurt and went ahead with the speech to a rally at a football stadium, which was broadcast live on state TV.

However, Iran`s state-owned Press TV has denied the attack.

Arab TV reports said a number of people were wounded in the attack.

Dubai-based Al Arabiya television said the attacker hit a car carrying journalists. The attacker was detained, it added.

"This morning a hand grenade exploded next to a vehicle carrying reporters accompanying the president in Hamedan," Iranian website Khabaronline reported.

"Ahmadinejad`s car was 100 metres (yards) away and he was not hurt."
