Kim Jong-nam death

The pair, who are employed by the World Food Programme (WFP), arrived in Beijing on Thursday.

North Korea and Malaysia on Tuesday banned each other's citizens from leaving, in a row over the killing of the North Korean leader's half-brother.

Kim Jong-nam was killed with a potent nerve agent at Kuala Lumpur airport.

Malaysia has not directly blamed North Korea for this, but there is widespread suspicion Pyongyang was responsible.

In the short and censored clip, the man says: "My name is Kim Han-sol, from North Korea, part of the Kim family."

He says he is with his mother and sister, but there are no details on the date or location. It's the Kim family's first public comment since the murder.

His father was killed in Kuala Lumpur airport on 13 February by attackers who smeared his face with VX nerve agent.

Officials at South Korea's Unification Ministry and National Intelligence Service say the man in the video is Kim Han-sol.

The extraordinary tit-for-tat actions come amid North Korean fury at Malaysia's ongoing investigation into his death at a Kuala Lumpur airport.

The North Korean leader's half-brother was killed with a potent nerve agent.

Malaysia has not directly blamed the North for this, but there is widespread suspicion Pyongyang was responsible.

North Korea has fiercely denied any accusations of culpability and the row over the killing - and who has the right to claim Mr Kim's body - has rapidly escalated over the past two weeks.

Malaysia's Attorney General Mohamed Apandi Ali said Ri Jong Chol was "a free man" as there was "insufficient evidence to charge him".

The estranged half-brother of North Korea's leader died on 13 February - he was poisoned with VX nerve agent.

Two women were charged with his murder on Wednesday.

Malaysia is hunting several North Koreans, including an embassy official, suspected of being involved in the murder.

The women, Doan Thi Huong from Vietnam and Siti Aisyah from Indonesia, allegedly smeared deadly VX nerve agent on Mr Kim's face in Kuala Lumpur airport on 13 February.

They appeared in court near Malaysia's capital, protected by special forces.

They could face the death penalty if convicted of murder.

No plea was recorded in the magistrates' court as only higher courts have jurisdiction over murder cases. But after the charge was read out, Doan Thi Huong said "I understand but I am not guilty," in English.

Attorney General Mohamed Apandi Ali said the women - from Indonesia and Vietnam - would be formally charged and could face death if convicted.

The women allegedly smeared a deadly chemical over Kim Jong-nam's face at a Malaysia airport earlier this month.

They have said they thought they were taking part in a TV prank.

"They will be charged in court under Section 302 of the penal code," the attorney general said, which is a murder charge with a mandatory death sentence if found guilty.

The older half-brother of North Korea's leader was poisoned at Kuala Lumpur airport, Malaysian police say.

Four of the seven suspects named by Malaysia work for Pyongyang's ministry of state security, intelligence officials in Seoul told MPs.

It is unclear which of the North Koreans wanted by Malaysia were meant.

Mr Kim died two weeks ago after two women accosted him in a check-in hall at the airport.

They say they thought they were taking part in a TV prank.

Mr Kim died last week after apparently being poisoned while waiting for a flight at a Kuala Lumpur airport.

There is growing speculation that his son, Kim Han-sol, has travelled to Malaysia to claim the body.

In a growing diplomatic row, Malaysia refused a request from the North Korean embassy to hand over the remains.

It wants a member of the Kim family to provide a DNA sample so his identity can be confirmed before the body is released.

Local police said that the woman was arrested at the airport in the capital Kuala Lumpur where Kim Jong-nam was targeted in an apparent poisoning on Monday.

She was in possession of a Vietnamese travel document.

Malaysian police say they are looking for "a few" other suspects.

Police said the arrested suspect, who was alone, was identified from CCTV footage taken at the airport. They named her as Doan Thi Huong, 28.
