North Korea has test-fired sea-to-surface strategic guided cruise missiles, state news agency KCNA reported Sunday, adding that the weapons “precisely” hit their targets.

“The war deterrence means of the armed forces of the DPRK are being perfected more thoroughly”, North Korean leader Kim Jong Un said as he oversaw Saturday’s test, the agency reported.

KCNA did not say where the test took place.

The weapons test by Pyongyang was the first since US President Donald Trump returned to the White House on Monday. Shortly before his inauguration, North Korea fired several short-range ballistic missiles into the sea.

Trump, who had a rare series of meetings with Kim during his first term in office, said in an interview aired Thursday that he would reach out to Kim again, calling the North Korean leader a “smart guy”.

This is the best option for dealing with the US.

Such joint military exercises regularly infuriate the nuclear-armed North, which decries them as rehearsals for invasion.

In late October, North Korea test-fired what it said was its most advanced and powerful solid-fuel intercontinental ballistic missile (ICBM). It then fired a salvo of short-range ballistic missiles days later.
