Nine other Malaysians are believed to still be stuck there after the two countries' diplomatic relations broke down over the killing of Kim Jong Nam, the estranged sibling North Korea's leader Kim Jong-un.
However, South Korea's Unification Ministry, a department of the government that works toward the reunification of North and South Korea, said they had no knowledge of the Cheollima Civil Defense group.
On Feb. 13, Kim Jong-nam was killed by two women who rubbed a deadly nerve agent on his face in a Malaysian airport. He also states that the video was made a few days after his father's murder. In the 40-second YouTube video, the black-clad young man said he is now with his mother and sister, without disclosing their whereabouts.
Amusing that, all who have good will towards Korea's people were hoping in 2012 that Han Sol's young uncle - who had also benefitted from a very privileged education in the West - would follow just such a path.
Malaysia has a remarkably open border, inviting visitors from across the region, and thousands of North Korean labourers have been employed in Malaysia.
The video could not be independently verified.
Kim Han-sol says that he and his family went into hiding.
In a YouTube clip published on March 7, Kim Han-sol identified himself as Kim Jong-nam's 21-year-old son.
South Korean intelligence officers said North Korean leader Kim Jong-un had issued standing orders for the elimination of his elder half-brother.
Pyongyang has accused Kuala Lumpur of subverting investigations as part of a conspiracy against it, leading to a worsening diplomatic spat that has resulted in both ambassadors being expelled, and reciprocal travel bans barring Malaysians from leaving North Korea and vice versa.
Najib declined to elaborate on the next steps: "If there's any negotiations, we can't do it through the media".
Experts hope an ad hoc tribunal on North Korea may be set up someday, as China would be expected to veto any move in the U.N. Security Council to refer its ally to the ICC. "There are no rules on how long you could keep a body in Malaysian hospitals, so we can wait", he told reporters in Balik Pulau here today.
Ambassador Embrechts is a very experienced diplomat with previous service in the Netherlands Embassy in Seoul between 1993 and 1997, was Dutch Ambassador to Malaysia between 2005 and 2009, and has been Ambassador to South Korea since 2015.
Najib has denounced North Korea's order "an abhorrent act, effectively holding our citizens hostage" and a violation of worldwide law.
Jong Nam died within 20 minutes of the attack.
