(CNN) -- Iran tested a missile-launching system and several types of short- and medium-range missiles Sunday, the state-run Press TV said.
A short-range missile is test-launched during war games in Qom, Iran, south of Tehran, on Sunday.
Earlier, the country's Islamic Revolutionary Guard Corps had said it would stage missile exercises beginning Sunday to promote the armed forces' defense capabilities.
The tests, which are expected to last until Monday, are code-named "Payghambar-e Azam 4" or "The Great Prophet 4," Press TV said.
The missiles, fired at targets around the country Sunday, included the Fateh-110, a short-range ground-to-ground missile, and Tondar-69, a short-range naval missile, the station said. Several models of medium-range Shahab missiles were tested at night, Press TV reported. Watch Iranian missile tests »
The final stage of the tests will be held Monday morning, when Iran plans to test the long-range Shahab missile, the station said.
In May, Iran said it tested a surface-to-surface missile that is capable of reaching parts of Europe.
At the time, a White House official said actions in Iran were noteworthy.
"Of course, this is just a test, and obviously there is much work to be done before it can be built and deployed. But I see it as a significant step forward in terms of Iran's capacity to deliver weapons," said Gary Samore, special assistant to the president on nonproliferation.
The latest test follows Iranian President Mahmoud Ahmadinejad's disclosure Friday that Iran was building a second uranium enrichment facility. Watch analyst's view on missile tests, nuclear tensions »
The United States and Israel believe that Iran is seeking nuclear weapons under the guise of a civilian nuclear energy program.
Iran has denied the allegation.
