Kim Jong -nam, the estranged half-brother of North Korean dictator Kim Jong-un, has been killed at an airport in Malaysia by North Korean agents who were reportedly wielding "poison needles."
Yonhap news said Kim Jong-nam, who is believed to be in his 40s, was killed on Monday morning in Kuala Lumpur.
Quoting government sources, other media reports claim Mr Kim died after being jabbed by a poisoned needle by two women in the city's airport.
The women are believed to be North Korean agents but have so far been able to evade a police hunt.
Police in Malaysia told Reuters that an unidentified North Korean man had died en route to hospital from Kuala Lumpur airport on Monday.
Mohmad Salleh, the Malaysian CID director, told the Telegraph: "Kim Jong Nam was feeling unwell on Monday morning while he was waiting for a flight to Macau at KLIA.
"He was taken to KLIA clinic for further treatment, but because of the condition he was in, he was rushed to Putrajaya hospital, but passed away soon after arriving.
"Police have classified the death of Kim Jong Nam as sudden death and are waiting for the full postmortem report to decide further action."
An employee in the emergency ward of Putrajaya hospital told Reuters that a deceased Korean who was born in 1970 and surnamed Kim had been taken there.
