Iran's test this weekend of a new surface-to-surface ballistic missile "likely" violated a UN resolution, a U.S. administration official told CNN on Monday, October 12.

Based on information the administration has so far, the test appears to be in violation of U.N. Security Council Resolution 1929, which stipulates that Iran cannot engage in any activities related to ballistic missiles.

The administration official emphasized, however, that the test is not in violation of the nuclear agreement reached in July between Iran, the U.S. and five other world powers because that accord is focused on restricting Iran's path to a nuclear weapon, CNN News reports.

A newer UN Security Council resolution, number 2231, implementing the deal and banning Iran from engaging in activities related to ballistic missiles designed to carry nuclear warheads is not yet in effect.

Over the weekend, state-run media reported that Iran successfully test-fired a new precision-guided, long-range missile.

The Emad (Pillar) surface-to-surface missile, designed and built by Iranian experts, is the country's first long-range missile that can be precision-guided until it reaches its target, said Brig. Gen. Hossein Dehqan, Iran's defense minister.
