Iran has successfully test-fired a new version of the domestically-built surface-to-surface missile, Defence Minister Ahmad Vahidi said Wednesday.

Vahidi announced that the new generation of Fateh-110 is a medium-range ballistic missile with improved precision in targeting, Press TV reported.

The new version of Fatah missile is a single stage solid propellant.

Iran has unveiled a series of domestically-produced weaponry over the past few weeks, which include the short range missile Qiam (Rising) and the Karrar -- Iran's first Unmanned Aerial Vehicle (UAV).

Tehran says the weapons are part of its doctrine of defence and are aimed at strengthening security in the region.
