TWO women accused of smearing a banned nerve agent on the face of the estranged half-brother of North Korea’s dynastic leader pleaded not guilty at their trial yesterday.

Siti Aisyah of Indonesia and Doan Thi Huong of Vietnam are suspected of using VX nerve agent to kill Kim Jong Nam at Kuala Lumpur airport.

The women insist that they thought they were playing a harmless prank for a hidden-camera TV show.
