Iran unveils its latest ballistic missile that it says has a range of 2000km
Authorities showed off the liquid-fuelled Khorramshahr-4 to journalists at an event in Tehran, with the missile on a truck-mounted launcher.
Defence Minister Gen. Mohammad Reza Ashtiani said the missile could be prepared for launch in a short period.
Iranian officials described the missile as having a 2,000km (1,240mile) range with a 1,500 kilogram (3,300-pound) warhead.
They also released undated video footage that they said showed a successful launch of the missile.

The Khorramshahr-4 is named after an Iranian city that was the scene of heavy fighting during the Iran-Iraq War in the 1980s.
Regional tensions likely played a role in Iran's missile display Thursday.
A miniature example of Jerusalem's golden Dome of the Rock on the Al-Aqsa Mosque compound, a holy site in both Islam and Judaism that Jews call the Temple Mount, stood next to the mobile launcher.
Iran views Israel as its archenemy and provides arms anti-Israeli militant groups in the Palestinian territories and surrounding countries.
Tensions between the two nations are high, particularly as Iran enriches uranium closer than ever to weapons-grade levels.
The Khorramshahr would be able to reach Israel.
It remains unclear, however, why the missile has been called Khorramshahr-4 as only two other variants of the rocket are publicly known.
It is modelled on North Korea's Musudan ballistic missile.
