Kim Yo Jong, the influential sister of North Korean leader Kim Jong Un, said UN secretary-general Antonio Guterres took a "prejudiced and irresponsible" attitude by echoing South Korea's unilateral claim over the September blast.

"The UN secretary-general's behaviour of echoing words of the provokers and patronising them without having proper understanding of the fact is not helpful to the detente," Kim said in a statement carried by the KCNA news agency.
