Iranian President Mahmoud Ahmadinejad has survived an attack on his convoy on Wednesday, Lebanon's Future television quoted the Iranian presidency as saying.
Al Arabiya television said an attacker had thrown a bomb at Mr Ahmadinejad's convoy in Iran on Wednesday before being detained.
Both television reports said some people had been wounded.
Dubai-based Al Arabiya cited its own sources as saying the bomb had hit a car carrying journalists and presidential staff.
Mr Ahmadinejad appeared on live Iranian television at a sports stadium in the western city of Hamadan. He was apparently well and made no mention of any attack, Reuters reports.
