The North Korean ambassador to Malaysia on Monday continued his grandstanding over the assassination of North Korean leader Kim Jong-un's half-brother Kim Jong-nam and subsequent investigation.

In a press conference in front of the embassy, Kang Chol blustered that his country "will categorically reject the result of the post-mortem" and accused Malaysian authorities of disregarding "elementary international laws and consular laws."

Embassy officials, apparently under massive pressure from their regime, have behaved increasingly erratically since Kim Jong-nam was killed at Kuala Lumpur International Airport last week.

The envoy's latest outburst came after Malaysian police on Sunday revealed the identities and CCTV pictures of five North Korean suspects in the killing, and after he had already been called in by the Malaysian Foreign Ministry for a drubbing over previous comments.

Kang also refused to accept that the victim was Kim Jong-nam. "We cannot trust the investigation by the Malaysian police," hsaid, echoing remarks at a press conference outside the morgue where Kim Jong-nam's body is stored. He said the victim had a passport in the name of Kim Chol and accused the Malaysian police of siding with South Korea to malign the North.

"It only increases the doubt that there could be someone else's hand behind the investigation," he said.

Kang reiterated his claim that Malaysian police initially told him that Kim had died of a heart attack on the way to hospital. Kang claimed Malaysian police are changing their stance as they are unable to find out the exact cause of death while demanding a DNA test with family members before handling the body over.
