Iran says it has test-fired an improved version of one of the country's medium-range missiles, an action the United States says contradicts Iran's claims of "peaceful intentions."
Iranian state television Wednesday showed video of the Sejil 2 missile launch. The missile has a range of about 2,000 kilometers, making it capable of hitting Israel and U.S. bases in southeastern Europe.
A White House spokesman, Mike Hammer, said the test "will increase the seriousness and resolve of the international community" to confront Iran over its nuclear program.
Tehran has repeatedly denied Western charges that it is trying to develop nuclear weapons under the cover of a civilian atomic energy program.
Iranian Defense Minister Ahmad Vahidi said the missile is meant as a deterrent.
British Prime Minister Gordon Brown said the missile launch makes the case for additional sanctions against Tehran.
The French Foreign Ministry said the test reinforces concerns about Iran's nuclear program, which the ministry said has no "identifiable civilian aim."
The U.S. and Israel have expressed concerns about Iran's nuclear capabilities, and they have not ruled out the possibility of using military action to stop the Islamic Republic from creating a weapon.
On Tuesday, U.S. lawmakers voted in favor of sanctions on foreign companies selling gasoline to Iran.
One lawmaker called the vote a response to Iran's continued rejection of President Barack Obama's efforts to engage Tehran.
The U.S. Senate must also approve the measure before it can be signed into law.
