Iran carried out a test launch of a medium-range ballistic missile on Sunday that exploded after 630 miles (1,010 km), a US official said.
The official, speaking on condition of anonymity, said the test was carried out from a site near Semnan, east of Tehran. The official added that the last time this type of missile was test launched was in July 2016.
The White House said it was aware that Iran had tested a missile, Reuters reports.
"We're looking into that. We're aware that Iran fired that missile. We're looking into the exact nature of it, and I'll try to have more for you later," White House spokesman Sean Spicer said during a press briefing.
