Japan calls North Korea's behaviour 'absolutely unacceptable'

Japan's Chief Cabinet Secretary Yoshihide Suga said on Friday that North Korea's remarks and behaviour were "absolutely unacceptable" and provocative to regional and international security.

Suga was speaking after North Korean leader Kim Jong Un vowed to make U.S. President Donald Trump pay dearly for threatening to destroy his country, and after North Korea's foreign minister was quoted as saying he believes the North could consider a hydrogen bomb test in the Pacific Ocean.

Japanese Defence Minister Itsunori Onodera said the comment by North Korean foreign minister Ri Yong Ho was utterly unacceptable.
