Tehran, Iran ? Iran’s military said Friday it successfully test-fired a missile not detectable by radar that can use multiple warheads to hit several targets simultaneously, a development that raised concerns in the United States and Israel.

The Fajr-3, which means “victory” in Farsi, can reach Israel and U.S. bases in the Middle East, Iranian state media indicated. The announcement of the test-firing is likely to stoke regional tensions and feed suspicion about Tehran’s military intentions and nuclear ambitions.

“I think it demonstrates that Iran has a very active and aggressive military program under way,” State Department deputy spokesman Adam Ereli said in Washington. “I think Iran’s military posture, military development effort, is of concern to the international community.”

Gen. Hossein Salami, the air force chief of Iran’s elite Revolutionary Guards, did not specify the missile’s range, saying how far it can travel depends on the weight of its warheads.

But state-run television described the weapon as “ballistic” – suggesting it is of comparable range to Iran’s existing ballistic rocket, which can travel about 1,200 miles and reach arch-foe Israel and U.S. bases in Iraq and the Persian Gulf region.
