The signs are slowly increasing that North Korea might test a nuclear weapon after a long time since 2017 in a bid to improve its arsenal and increase the pressure, said the USA and South Korean Officials.
Two U.S. officials told Reuters that there were signs including activity near the nuclear site that the North Korea is preparing for different sorts of tests.
North Korea has tested all the six nuclear experiments in deeper tunnels which were dug under the mountains and in 2018 those tunnels were bombed and closed in front of the foreign media but the international experts were not satisfied.
