An arrest warrant has been issued for the son of Akbar Hashemi Rafsanjani. Mehdi Hashemi, whose father is an influential cleric and former president known for his opposition to President Mahmound Ahmadinejad, has been living in Britain since last year’s election. Although no specific reason for the warrant has been given, hardliners have accused him of encouraging anti-government demonstrations. During last year’s protests, authorities briefly detained the cleric’s daughter.
