Iran's navy said Sunday it test-fired an advanced surface-to-air missile during a drill in international waters near the strategic Strait of Hormuz, the passageway for one-sixth of the world's oil supply. Iran's state TV said the missile, named Mehrab, or Altar, is designed to evade radar and was developed by Iranian scientists. The report said the missile was tested Sunday but provided no further details. A leading Iranian lawmaker said the sea maneuvers serve as practice for closing the Strait of Hormuz if the West blocks Iran's oil sales. The drill, which could bring Iranian ships into proximity with US Navy vessels that operate in the same area, is Iran's latest show of strength in the face of mounting international criticism over its nuclear program. The West fears Iran's program aims to develop atomic weapons, a charge Tehran denies, insisting it's for peaceful purposes only.
