Iran's supreme leader has replaced the head of the feared militia at the center of the postelection crackdown with a senior military officer under U.N. sanctions for links to the country's ballistic missile program, state media reported.
The Basiji militia, whose members operate in plain clothes and often wield crude weapons, was blamed for much of the violence against crowds protesting President Mahmoud Ahmadinejad's disputed June 12 reelection.
