In this Tuesday, April 16, 2019, photo provided by the North Korean government, North Korean leader Kim Jong Un inspects fighter combat readiness of Unit 1017 of the Air and Anti-aircraft Force of the Korean People's Army, in an unknown location in North Korea. Kim is cautiously turning up the heat after his unsuccessful summit with U.S. President Trump in Hanoi two months ago. Returning to military optics for the first time in five months, Kim paid a surprise visit to the Air Force base and followed that up the next day by supervising the test of what the North’s official media described ominously – but ambiguously, and without any photos or video – as a new type of “tactical guided weapon”. Independent journalists were not given access to cover the event depicted in this image distributed by the North Korean government.

Korean language watermark on image as provided by source reads: “KCNA” which is the abbreviation for Korean Central News Agency.
