Zaidi has been in custody since the shoe-throwing incident, amid claims that he has been badly beaten.

Urumiye News said the latest protest came when a disturbance broke out after a vehicle in the presidential convoy struck an elderly man who walked onto the road to try and hand Ahmadinejad a letter.

This breach of etiquette was something that neither side ever wanted to see happen. Therefore, expressing regret over this incident is the the most we can say.
