Iran test fired nine missiles on Wednesday, including an upgraded long-range missile that could reach Israel.
The tests of the new Shahab-3 missile with a range of 1,250 miles came during Iranian war games and were shown on state television.
The White House immediately condemned the test.
"The Iranian regime only furthers the isolation of the Iranian people from the international community when it engages in this sort of activity," said Gordon Johndroe, spokesman for the National Security Council. "They should also refrain from further missile tests if they truly seek to gain the trust of the world."
But Iranian official defended the action. The tests "demonstrate our resolve and might against enemies who in recent weeks have threatened Iran with harsh language," said Gen. Hossein Salami, head of Iran’s air force, according to the television report.
