Mistery Of Kim's half-brother Murder

On Monday, the half-brother of North Korean leader Kim Jong-un was killed in Malaysia. The BBC's Karishma Vaswani in Kuala Lumpur dissects a week of mystery and intrigue.

BBC: It's been almost a week since the mysterious death of a Korean man at Kuala Lumpur airport KLIA2 and there are still no real answers.

Initially, Malaysia refused to identify the dead man as Kim Jong-nam, saying just that the passport he had on him was under the name Kim Chol. This despite South Korea's insistence that it was indeed him, killed on the orders of North Korea's brutal regime. Malaysia finally confirmed for the first time on Wednesday that the dead man was indeed the half-brother of the North Korean leader.

Zahid Hamidi, Malaysia's deputy prime minister, told reporters: "I think he carries two different identities. Probably this [passport] is an undercover document."

Malaysia's cautious handling of this case has been evident from the start. The police have been sparing with their details, with official statements about arrests coming hours after they've already been widely reported. There have also been conflicting and often contradictory accounts from different divisions of the police - national and district - adding more confusion to the story.

But here's what we do know: three people have been arrested so far. Two women are amongst them. Police say one is Indonesian while the other was carrying a Vietnamese passport. A third suspect - a Malaysian man police say is the boyfriend of the Indonesian - has also been detained. Police have detained the suspects for seven days for further questioning.

Still, nothing is known about how closely connected they are to the death of Kim Jong-nam, nor indeed why and exactly how he died. Malaysian police have told me that the two women were both identified from CCTV camera footage captured at the scene of the alleged crime. I went to the airport terminal where the attack happened to see for myself how it might be possible to get away with murder in broad daylight.

The facts in this case are murky to say the least. But based on police reports, this is what appears to have happened. On Monday, Kim Jong-nam was about to board a flight. He is thought to have arrived in Kuala Lumpur on 6 February and was on his way back to Macau, where it is believed he lived. But while he was at the airport, some police reports say at least one woman is thought to have accosted him, and covered his face with a cloth doused in some sort of burning or poisonous chemical.

He then went to the information counter and is thought to have asked for help. Subsequently it appears he was taken to the medical clinic in the airport from where he was sent to hospital, dying en route. But when I spoke to staff at the airport who may have witnessed what happened, no-one was willing to talk to me. At least two people said they had been told by police and their bosses not to speak to the media or divulge any details of what happened.

So there's a lot we still don't know.

What kind of chemical was used in the apparent poisoning? How exactly did he die? The post-mortem examination of his body has been completed, but details have yet to be released to the public.

We also don't know what he was doing in Malaysia, although we understand that he did come here fairly frequently.

Second woman from Jakarta slum

The Indonesian woman who was arrested on Thursday, Siti Aishah, had lived a quiet life in a slum district of Jakarta before going to find work in Malaysia, residents in the western neighbourhood of the Indonesian capital said. According to Malaysian media reports, she stood in front of Kim to distract him while her accomplice approached from behind.In Jakarta, Aishah had worked for a time in the tailoring business in the house of her ex-husband's family, sewing clothes by hand, former neighbours in the Tambora district said.
