President Mahmoud Ahmadinejad has survived a grenade attack on his convoy in western Iran.

The blast from a homemade bomb took place today in Hamedan as Mr Ahmadinejad was travelling through a busy crowd to make an address at a sports stadium.

The president was unhurt, but other people in the convoy were injured. One person has been arrested over the incident.

Mr Ahmadinejad continued with his plans to make a speech in Hamadan, which was broadcast on Iranian television. He made no mention of an assault.
Iranian officials denied Mr Ahmadinejad was targeted, with the state-run Press TV adding 'no such attack had happened'.
Officials said the blast was caused by a firework being set off by someone in the crowd to cheer the president.

'It was a firecracker, and a statement will be released soon,' an official inthe president's media office said.
However, the conservative website Khabaronline said: 'This morning a hand grenade exploded next to a vehicle carrying reporters accompanying the president in Hamedan.

'Ahmadinejad's car was 100 metres away and he was not hurt.'
Al Arabiya television said an attacker had thrown a bomb at Ahmadinejad's convoy before being detained.
There was no immediate claim of responsibility for the attack, although the populist, hardline Mr Ahmadinejad has accumulated enemies in conservative and reformist circles in the Islamic Republic as well as abroad.

Iran has also provoked anger from the UK and the U.S. over its controversial nuclear weapons' programme, which it claims is for peaceful purposes.
During a speech to a conference of expatriate Iranians in Tehran on Monday, Ahmadinejad said he believed he was the target of an assassination plot by Israel.
