KUALA LUMPUR (Reuters) - 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.
