Iran is unveiling a short-range solid fuel ballistic missile, an upgraded version that the government says can more accurately pinpoint targets.

The surface-to-surface Fateh-313, or Conqueror, was unveiled Saturday at a ceremony marking Defense Industry Day and attended by President Hassan Rouhani. State television showed footage of the missile being fired from an undisclosed location. The missile is a newer version of Fateh-110 and has a quicker launch capability, a longer lifespan and can strike targets within a 500-kilometer (310-mile) range, the report said.

U.N. Security Council Resolution 2231, which endorsed a landmark nuclear deal reached between Iran and world powers, has called on Iran not to undertake any activity related to ballistic missiles capable of delivering nuclear weapons. Iran says none of its missiles are designed for that purpose.
