SEOUL: North Korean leader Kim Jong-Un said his country has successfully miniaturised a thermo-nuclear warhead, as Pyongyang on Wednesday continued to talk up its nuclear strike capabilities amid rising military tensions on the Korean peninsula.
While the North has boasted of mastering miniaturization before, this is the first time Kim has directly claimed the breakthrough that experts see as a game-changing step towards a credible North Korean nuclear threat to the US mainland.
His comments came a day after the North’s powerful National Defence Commission threatened pre-emptive nuclear attacks on South Korea and the US mainland, as Seoul and Washington kicked off large-scale joint military exercises.
