TEHRAN, Iran — Iran test-fired nine long- and medium-range missiles today during war games that officials said aimed to show the country can retaliate against any U.S. or Israeli attack, state television reported.

Oil prices jumped on news of the missile tests, rising $1.80 to $137.84 a barrel in electronic trading on the New York Mercantile Exchange.

The military exercise was being conducted at the Strait of Hormuz, a strategic waterway at the mouth of the Persian Gulf through which about 40 percent of the world's oil passes. Iran has threatened to shut down traffic in the strait if attacked. It was not clear, however, whether the missile test also took place near the strait.

Gen. Hossein Salami, the air force commander of Iran's elite Revolutionary Guards, said the exercise would "demonstrate our resolve and might against enemies who in recent weeks have threatened Iran with harsh language," the TV report said.

Footage showed at least six missiles firing simultaneously, and said the barrage included a new version of the Shahab-3 missile, which officials have said has a range of 1,250 miles and is armed with a 1-ton conventional warhead. The television report did not specify where the launch took place.

That would put Israel, Turkey, the Arabian peninsula, Afghanistan and Pakistan within striking distance.

"Our hands are always on the trigger and our missiles are ready for launch," the official IRNA news agency quoted Salami as saying today.

The report comes less than a day after Iranian President Mahmoud Ahmadinejad dismissed fears that Israel and the United States could be preparing to attack his country, calling the possibility a "funny joke."

"I assure you that there won't be any war in the future," Ahmadinejad told a news conference Tuesday during a visit to Malaysia for a summit of developing Muslim nations.

But even as Ahmadinejad and other Iranian officials have dismissed the possibility of attack, Tehran has stepped up its warnings of retaliation if the Americans — or Israelis — do launch military action, including threats to hit Israel and U.S. Gulf bases with missiles and stop oil traffic from the Gulf.

U.S. Secretary of State Condoleezza Rice called today's tests "evidence that the missile threat is not an imaginary one."

"Those who say that there is no Iranian missile threat against which we should build a missile defense system perhaps ought to talk to the Iranians about their claims," Rice said while traveling in Sofia, Bulgaria.

A White House spokesman called the tests "completely inconsistent with Iran's obligations to the world."

"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," he added, speaking from Japan where President Bush is attending the Group of Eight summit.
