Malaysia has stepped up diplomatic measures against North Korea in an escalating row over the killing of Kim Jong-nam, the half-brother of North Korea’s leader Kim Jong-un.
Kim Jong-nam died in mysterious circumstances last week at an airport in the Malaysian capital Kuala Lumpur.
Police believe he was poisoned.
Malaysia has recalled its ambassador from the North Korean capital Pyongyang and has summoned the North Korean ambassador “to seek an explanation”.
Malaysian police say they are now looking for four North Koreans.
North Korea’s ambassador to Kuala Lumpur, Kang Chol, told reporters that he did not trust the Malaysian inquiry.
“It has been seven days since the incident but there is no clear evidence on the cause of the death and at the moment we cannot trust the investigation by the Malaysian police even though its results [have yet to be] obtained.
“It only increases the doubt that there is someone else’s hand behind the investigation.”
He said that the incident had been “politicised” and referred to the victim as Kim Chol – the alias used by the dead man.
Meanwhile a video which apparently shows CCTV footage of the attack on Kim Jong-nam has surfaced and aired on Japanese television.
Despite widespread speculation that North Korea was behind the killing, there has been no definitive evidence and Pyongyang has not issued an official statement yet.
South Korea has accused the North of orchestrating the incident, saying on Monday it was evidence of North Korean “terrorism getting bolder”.
What has led to the diplomatic spat?
Malaysia was one of very few countries to maintain diplomatic relations with North Korea, but this killing has strained ties.
Malaysia has refused to accede to North Korean demands to release Kim’s body into their custody without an autopsy.
In comments on Friday, Mr Kang, the North Korean ambassador, said Malaysia was colluding with “hostile forces”. That provoked an angry response from the Malaysian foreign ministry.
It said his accusation was “baseless”, adding that it was their responsibility to conduct an investigation as Kim had died on Malaysian soil.
