CAIRO: Egypt's security arrested four men who were protesting outside a Cairo mosque, where the Iranian President Mahmoud Ahmadinejad was praying.
The men, including a Syrian, belong to the ultra-conservative Sunni Salafist movement.
One man threw a shoe at Ahmadinejad, a Shiite, who was never in any danger.
The Al-Hussein Mosque is revered by Shiite Muslims, who are widely disliked by conservative Sunni Muslims, including members of the Muslim Brotherhood.
Egypt's President Mohammed Morsi was previously a member of the Brotherhood.
Many Sunni Muslim groups have denounced the Iranian president’s visit to Cairo and have called on Egypt’s government to prevent Ahmadinejad from visiting any religious sites that are significant to Shia Muslims.
Ahmadinejad met with Islam's most senior scholar at Al Azhar shortly before he went to pray at the Al-Hussein Mosque.
