The ambassador of the Democratic People's Republic of Korea denied on Monday confirming for Malaysian authorities that a man whose death is under investigation in Kuala Lumpur was Kim Jong-nam, the elder half-brother of DPRK top leader Kim Jong-un.

The ambassador, Kang Chol, made the remark after Malaysia's Foreign Ministry summoned him on Monday to provide an explanation over a statement he had made on the police investigation of the death.

In a strongly worded statement on Friday, Kang had accused the Malaysian government of having "something to conceal" in its investigation, purposely delaying the release of the body and conducting the autopsy unilaterally.
