The scene of the brazen February 13 killing of the North Korean leader's half brother was swept by civil defence personnel in hazmat suits overnight, after Malaysia revealed Friday the victim died from VX nerve agent which is so deadly it is classified as a weapon of mass destruction.
Two women can be seen shoving something into Kim's face in leaked CCTV airport footage of the ambush. He later suffered a seizure and was dead before he reached hospital.
One of the two female suspects now in custody, 25-year-old Indonesian Siti Aisyah, reportedly told a senior diplomat Saturday she had been paid just RM400 ($90) for her role, adding she believed she was handling a liquid like "baby oil".
The other woman in custody, Vietnamese Doan Thi Huong, 28, told Hanoi officials she had been tricked into killing Kim and thought she was taking part in a prank for a comedy video.
Police sealed off large areas of the terminal's two departures hall where the attack was carried out ahead of the sweep for traces of the highly potent toxin as a few curious onlookers watched.
Authorities later declared the area safe after nothing harmful was found.
"The police cordon was at three areas -- the scene of the attack, the bathroom where the two female suspects washed their hands and pathway leading to the airport clinic -- (and) has been taken down," a police spokesman said.
