A former head of Iran’s Revolutionary Guards, Mohsen Rezai, has registered as a candidate for the presidential election next month. He is seen as a conservative, but has been highly critical of President Mahmoud Ahmadinejad. Mr Rezai is one of five leading Iranians wanted by Argentina for their alleged role in a 1994 bombing. The attack at a Jewish organisation killed 85 people. Iran insists that it had nothing to do with the attack.
