Four men suspected of killing the North Korean leader's half-brother at a Malaysian airport changed their clothes and appearance to escape detection, a police witness said on Thursday.
The four, who are still at large, are charged together with two women - Indonesian Siti Aisyah and Doan Thi Huong from Vietnam - with killing Kim Jong Nam at Kuala Lumpur airport's budget terminal on Feb. 13.
Prosecutors in the Malaysian court say Siti Aisyah and Huong conspired with the men to murder Kim, by smearing his face with liquid VX, a chemical poison banned by the United Nations.
