Syrian president Bashar al-Assad was the victim of a failed assassination attempt on Monday, claimed Iranian sources.

The failed attack allegedly took place as he arrived at the al-Hassan mosque in Damascus to perform Eid al-Fitr prayers.

Iran's Mehr and Isna state agencies based their claims on a news alert by Lebanon's al-Manar television, the mouthpiece of the Hezbollah party.

Iran's Tabnak news site reported that Assad had greeted citizens at the mosque and that he appeared in good health.

The Iranian sources said Syrian security sources did not address the details of the attempt on Assad's life.

It noted that he appeared well in the footage that showed him upon his arrival at the mosque and as he greeted the people before the prayer.

Isna later said that al-Manar did not report further about the attack, while Syria's state news agency SANA made no mention of it.

Mehr reported that Syria's al-Watan daily had dismissed the claims of an assassination as a "rumor".

It accused opponents of the regime of manipulating the image that accompanied the news of the attack.

Iran's Tasnim agency noted that al-Manar did not publish a news report about the assassination, while the Syrian opposition did.
