A South Korea spy agency now says North Korean leaders of Kim Jong Un's ordered the assassination of his half-brother. The intelligence service says the killing was carried out by two of the North Korean regime's ministries. CNN international correspondent Alexandra Field live in Kuala Lumpur, Malaysia with the latest on the investigation. This is certain to outrage the North Korean leader. How confident are South Korean authorities about this?</s>ALEXANDRA FIELD, CNN INTERNATIONAL CORRESPONDENT: Yes, it will no doubt infuriate the North Korean leader but a South Korean spy agency is going public, pinning this plot right to the top. They're doing it regardless and they say that this was a coordinated effort, Chris, involving two different assassination groups and also a support group. And they say that the four North Korean suspects who were believed to have left Malaysia immediately in the aftermath of the attack are all North Korean government officials.</s>FIELD: Two women captured on CCTV video accused of carrying a weapon of mass destruction into Kuala Lumpur's busy airport. (Video playing) This is the moment of the attack. Kim Jong Nam, the half-brother of North Korea's dictator Kim Jong Un, dies 15 or 20 minutes later. Twelve days after, authorities find traces of the highly lethal nerve agent VX on his face and in his eyes. The airport terminal that's been operating as normal is finally swept by crews in protective suits. They give it the all-clear. Police defend the timeline, saying they took protective measures once they fully understood the danger.</s>UNIDENTIFIED MALE: It is only on the Friday evening we received the call. We get confirmation. We feel that we have to do this screening process.</s>FIELD: Authorities from the suspects' home countries, Vietnam and Indonesia, say both women claimed they thought they were part of a prank. In Indonesia, the aunt of Siti Aisyah tells CNN weeks earlier her niece told her about a new job on a foreign T.V. show.</s>SITI AISYAH'S AUNT (through translator): At the beginning she was asked to put a hand-body lotion onto hands of strangers in order to make them angry. And then, at the second occasion, she was asked to put tomato sauce onto other people's body. So just basically doing work like that.</s>FIELD: Her niece must have been manipulated, she says. But Malaysian police say the women were trained to kill. Aisyah told Indonesia's deputy ambassador she was given a liquid similar to baby oil, paid about $90 U.S. dollars, and assigned the job by people she described as Japanese or Korean. Investigators say the women were given that deadly substance by four North Korean men who fled the country immediately after the attack. They had been renting an apartment here in Kuala Lumpur. Almost two weeks after Kim Jong Nam was killed police raided it, collecting samples that have now been sent to a lab for testing. The women arrived in Malaysia less than two weeks before the attack, one of them checking into at least two different hotels in the two days before it. The staff remembers her as the woman carrying a giant teddy bear.</s>FIELD: Memorable, indeed
