Iran’s former president was set upon by an angry stick-wielding mob today amid celebrations of the 30th anniversary of the Islamic Revolution on the streets of Tehran. The attack on Mohammed Khatami came just two days after the reformist cleric announced he would be running against the hardline incumbent Mahmoud Ahmadinejad in June's presidential elections. According to Mr Khatami’s Baran Foundation, the attackers were repelled by his own supporters, who chanted, “Khatami, Khatami, we support you.” Mr Khatami was escorted from the street by his bodyguards who took him to shelter in a nearby building.
