Ali Mousavi Was Assassinated, Iranian Police Say

(AP) TEHRAN, Iran — Iran's deputy police chief says the nephew of opposition leader Mir Hossein Mousavi was assassinated by unidentified assailants and not killed by security forces.

Ali Mousavi was one of at least eight people killed during clashes Sunday when tens of thousands of opposition supporters protested against the government.

The opposition says Ali Mousavi was shot and killed by security forces. But Iran's deputy police chief, Ahmad Reza Radan, is quoted by the official IRNA news agency as saying that the way he was killed suggests he was assassinated while walking.

The New York Times has quoted a family friend as saying Ali Mousavi was run over by a vehicle outside his home in an assassination.
