As the United Nations Security Council met on Tuesday to discuss Iran’s Sunday test-launching of a medium-range ballistic missile, military officials confirmed that the country also secretly tested another missile in early December.
Tehran fired a Shahab-3 on Dec. 6 at Semnan, though the missile’s destination is unknown. The intermediate range ballistic missile is modeled off a North Korean design and has a range of 800 miles, according to a report. Officials said the test was likely in breach of UN Resolution 2231, which was signed after the Iran nuclear deal. It called for a stop to “any activity” related to ballistic missiles’ carrying nuclear weapons.
On Monday, the U.S. learned Iran had fired a ballistic missile approximately 140 miles east of Tehran on Sunday, the first apparent breach of the UN resolution.
Iran has carried out six known ballistic missile tests since the nuclear agreement and UN resolution took effect in 2015.
