Iran conducted its first ballistic missile test under Donald Trump’s presidency, although it apparently failed on reentry. The Khorramshahr medium-range ballistic missile flew 600 miles from the test site outside Semnan before exploding in a failed test of a reentry vehicle, officials said. Iran defense minister Brigadier Gen. Hossein Dehqan said in September that Iran would start production of the missile.
UN resolution 2231 called on the Islamic Republic not to conduct such tests for eight years. However, this is at least Iran's second test since the the resolution was put in place in July 2015, days after the Iran nuclear deal was signed.
