Iran often stages war games or tests weapons to show its determination to counter any attack by foes including Israel and the United States, which accuse the Islamic Republic of seeking to develop nuclear bombs. Tehran denies the charge.
"Iran test fires new long range missile," Press TV, Iran's English-language television station, said in a scrolling headline without giving details.
The Press TV report came less than a week after a top Iranian military commander said that Iranian missiles could now reach Israeli nuclear sites.
Israel has not ruled out military action if diplomacy fails to end the row over Iran's nuclear aims, echoing US policy, though US President Barack Obama has also offered to engage Iran in direct talks.
Iran has often said it has missiles able to reach Israel but had not previously mentioned such specific targets.
