Tehran, Iran (CNN) -- Iran has successfully test-fired 14 missiles during military drills, Iranian news agencies reported Tuesday.
Following the unveiling of several missile silos Monday, Tuesday's exercises are the second day of war games code-named the "Great Prophet Six."
According to Iran's IRIB news agency, the Islamic Revolutions Guards Corps fired three Shabab ballistic missiles and 11 Zelzal short-range missiles to test the missiles "'precision, navigation and interceptive capability."
Airing video of one of the facilities as it began a new round of military exercises, Iran announced Monday that it has built its first ballistic missile silos. The hardened, underground launch sites will allow Iranian commanders to fire missiles more quickly, Iran's state-run Press TV reported. A military statement carried by the official Islamic Republic News Agency said the silos were capable of launching long-range missiles.
Iran's development of missile and nuclear fuel technology has led to U.N. sanctions and accusations from the United States that the clerical regime is trying to develop nuclear weapons.
Iran says it has a right to peaceful nuclear technology, but the International Atomic Energy says it can't verify whether Tehran's nuclear program remains entirely peaceful.
The United States and the Soviet Union built more than 1,400 silos to protect their long-range missiles during the Cold War era.
In the Iranian statement, military spokesman Col. Asghar Ghelichkhani said the facilities were designed and built with domestic expertise.
Western observers say Iran currently has missiles capable of hitting targets up to about 1,300 kilometers (800 miles) away, a range that would cover nearly the entire Middle East and part of southeastern Europe. Iran also launched its first satellite in 2009.
