North Korea says it has test-fired a new “tactical guided weapon” with a “powerful warhead”, the first such test since talks between Donald Trump and Kim Jong-un ended without agreement.
State media gave few details, but analysts say this is unlikely to be a return to the long-range missile tests seen as a threat to the US.
A similar test last November was viewed as an attempt to pressure the US.
There has been little progress in nuclear talks since the last summit.
In February, Donald Trump and Kim Jong-un met in the Vietnamese capital of Hanoi to discuss denuclearisation, but discussions broke down and both leaders left abruptly.
Last week, Mr Kim said Mr Trump needed to have the “right attitude” for talks to continue.
