Though it's hard to tell what's going on in the video above, apparently it's footage of Iranian President Mahmoud Ahmadinejad getting a shoe thrown at him outside Cairo's al-Hussein mosque.
RT, citing Turkey's Anatolia news agency, reports that the alleged shoer was a Syrian who has been taken into custody:
The attacker, who attempted to hit President Mahmoud Ahmadinejad as he left a mosque, is reported to be a young man with "a Syrian accent". Egyptian security forces managed to seize and arrest the man following the incident.
The attacker was heard chanting anti-Iranian slogans for supporting the Syrian government, the news agency noted.[view whole blog post ]
