Iran test-fired nine long- and medium-range missiles Wednesday during war games that officials say are in response to U.S. and Israeli threats, state television reported.
Gen. Hossein Salami, the air force commander of Iran's elite Revolutionary Guards, was quoted as saying the exercise would "demonstrate our resolve and might against enemies who in recent weeks have threatened Iran with a harsh language."
Wednesday's war games were being conducted at the mouth of the Strait of Hormuz, a strategic waterway where about 40 percent of the world's oil passes through.
Footage showed at least three 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 (2,000 kilometers) and is armed with a 1-ton conventional warhead.
That would put all of Israel, Turkey, the Arabian peninsula, Afghanistan and Pakistan within the missiles' reach.
"Our hands are always on the trigger and our missiles are ready for launch," the official IRNA news agency quoted Salami as saying Wednesday.
The tests come 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.
Iranian officials have been issuing a mix of conciliatory and bellicose statements in recent weeks about the possibility of a clash with the U.S. and Israel.
A White House spokesman called Wednesday's 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 U.S. President George W. Bush is attending the Group of Eight summit.
Israel's military sent warplanes over the eastern Mediterranean for a large military exercise in June that U.S. officials described as a possible rehearsal for a strike on Iran's nuclear facilities, which the West fears are aimed at producing atomic weapons.
Iran says its nuclear program is geared only toward generating electricity, not weapons.
For months, Ahmadinejad and other Iranian officials have said they don't believe the U.S. will attack because of its difficulties in Iraq, domestic worries and concerns over the fallout in the region.
At the same time, Tehran has stepped up its warnings of retaliation if the Americans - or Israelis - do attack it, including threats to hit Israel and U.S. Gulf bases with missiles and stop oil traffic through the vital Gulf region.
In late June, Vice Adm. Kevin Cosgriff, who was then the commander of the U.S. Navy's 5th Fleet, said any attempt by Iran to seal off the Strait of Hormuz would be viewed as an act of war. The U.S. 5th Fleet is based in Bahrain, across the Gulf from Iran.
The Israeli exercise was widely interpreted as a show of force as well as a practice on skills needed to execute a long-range strike mission.
Shaul Mofaz, an Israeli Cabinet minister, set off an international uproar last month by saying in a published interview that Israel would have "no choice" but to attack Iran if it doesn't halt its nuclear program. Mofaz is a former military chief and defense minister, and has been Israel's representative in a strategic dialogue on Iran with U.S. officials.
On Wednesday, Israeli government spokesman Mark Regev said Israel "does not desire hostility and conflict with Iran."
"But it is clear that the Iranian nuclear program and the Iranian ballistic missile program is a matter of grave concern," Regev said.
The Guards and Iran's regular army routinely hold exercises two or three times a year.
