Nuclear-armed North Korea said it had carried out "a very important test" at its Sohae long-range rocket site, state meda reported Sunday, after U.S. President Donald Trump said he doesn't think Pyongyang will engage in hostile acts and interfere with the upcoming presidential election.

"The Academy of the National Defence Science of the Democratic People's Republic of Korea made a report on the results of the successful test of great significance to the Central Committee of the Workers' Party of Korea," the short dispatch by the official Korean Central News Agency said without revealing details of what exactly was tested Saturday.

"The results of the recent important test will have an important effect on changing the strategic position of the DPRK once again in the near future," it added, using the acronym for the North's official name, the Democratic People's Republic of Korea.
