Siti Aisyah, who is Indonesian, and Doan Thi Huong, who is Vietnamese, face the death penalty if convicted of deliberately killing Kim Jong Nam.
The judge and others involved in the murder trial of Kim Chol or Kim Jong-nam, the brother of North Korean leader Kim Jong-un visited the alleged scene at Kuala Lumpur International Airport 2 (klia2) here today.
Kim Jong Nam died after VX nerve gas was thrust into his face at the airport.
Kim Jong Nam had been the heir apparent to the North Korean dynasty in the 1990s, but was exiled after being caught trying to enter Disneyland in Japan.
Judge Datuk Azmi Ariffin arrived with a convoy of police escorts, deputy public prosecutors, defence counsels and court officials.
The judge, prosecutors, defence lawyers and representatives of the women's home countries were escorted inside the Kuala Lumpur airport by heavily armed police on a visit meant to give the trial participants a better perspective of events as they unfolded.
At 10am, both accused, Siti dressed in black and Doan in a baju kurung, were hurriedly led through the departure terminal towards the self check-in kiosk and then to the Bibik Heritage restaurant on Level 2.
Exhausted by the exertion of moving around the airport in bulletproof vests, both Siti and Doan were given wheel chairs to move midway through the murder trail walk.
According to their respective counsels, both suspects opted to use the wheelchair as they had been exhausted from wearing their bullet vests weighing 1kg each during their walk around the airport.
Pyongyang has denied any involvement in the 13 February killing, but four men - believed to be four North Koreans who fled Malaysia on the day of murder - have also been charged in the case.
They are expected to visit the check in hall where Mr Kim appeared to have been attacked, and the medical centre where he sought assistance.
