North Korea conducted another rocket engine test as part of its efforts to develop an intercontinental ballistic missile, according to multiple reports Thursday.
The test follows about a dozen missile launches this year, as well as three engine tests in March.
The United States assessed the Thursday test could be for the smallest stage of an ICBM rocket engine, according to Reuters, which cited an unnamed U.S. official.
U.S. officials have warned that North Korea is on the path to successfully developing an ICMB capable of hitting the United States unless something changes.
