The Guards' Sepahnews website said the missile was named the Khaybarchekan after a victorious battle fought by the Prophet Mohammed in the seventh century.

Armed forces chief of staff Mohammad Bagheri described it as a strategic, "long-range" missile.

Sepahnews said the missile has a range of 1,450 kilometres (about 900 miles), runs on solid fuel and is capable of penetrating anti-missile systems.

It was unveiled during a visit to a surface-to-surface missile base of the Guards' air force, with the chief of the aerospace department Amirali Hajizadeh present.

"Its manoeuvrability and extreme speed allow it to reach targets within a radius of 1,450 kilometres," the website said.

The United States reacted by criticizing Iran's weapons development.

"Iran's development and proliferation of ballistic missiles poses a threat to the international security and remains a significant nonproliferation challenge," State Department spokeswoman Jalina Porter told reporters.

"We continue to use a variety of nonproliferation tools to prevent any further advancement of Iran's missile programme, and its ability to proliferate technology to others," Porter added.

Iran has the largest arsenal of missiles in the Middle East.

On December 24, the Islamic republic fired 16 ballistic missiles to conclude military drills described by generals as a warning to Israel.

The Jewish state is located little more than 1,000 kilometres from Iran's western frontier.

Bagheri said on Monday that Iran was "self-sufficient in terms of military equipment", noting it could become one of the world's largest arms exporters if US sanctions were lifted.

The International Institute for Strategic Studies (IISS) says Iran has about 20 types of ballistic missiles as well as cruise missiles and drones.

Their capabilities vary, with the Qiam-1 having a range of 800 kilometres and the Ghadr-1 able to reach 1,800 kilometres.

The IISS, a London-based think tank, says Iran's current priority is to increase the accuracy of its missiles.
