North Korea Threatens To Test Hydrogen Bomb

North Korea says it may test a hydrogen bomb over the Pacific Ocean after US President Donald Trump threatened to destroy the country, whose leader responded by promising to make a "mentally deranged" Trump pay dearly for his threats.

Speaking in New York City on Friday, Ri Yong-ho, North Korea's foreign minister, said his country could consider a hydrogen bomb test on an unprecedented scale on the Pacific Ocean, South Korea's Yonhap news agency reported.
