A suspect in the poisoning death of the North Korean leader's half brother wrote to her parents from jail, asking them to pray for her but saying "don't think about me too much."

Siti Aisyah, an Indonesian mother who worked in Malaysia, appeared in court Tuesday along with a second suspect, Doan Thi Huong of Vietnam. Their trial was formally transferred to the High Court as the lower court had no jurisdiction to hear a murder case.

They are the only people who have been arrested in the assassination of Kim Jong Nam at the Kuala Lumpur airport on Feb. 13.

The suspects are accused of smearing VX nerve agent on Kim's face in the crowded airport terminal; he died soon afterward. The women have said they were duped into thinking they were playing a harmless prank for a hidden-camera show.

Yusron Ambary, counsellor at the Indonesian Embassy, said Siti wrote a letter to her parents recently, asking them not to worry about her.

"I am in good health. Just pray. Don't think about me too much. Keep healthy and pray at night. I have a lot of people helping me. The embassy officials always come to see me, my lawyers also. Don't worry. Pray for me so that the case will be over soon and I can go back home. Send my love to my son Rio," he read from the letter to reporters outside the courtroom.

Armed escorts accompanied the women, who smiled at their embassy representatives as they were brought to the dock.

Prosecutor Iskandar Ahmad said the date for their first appearance in the High Court would usually be within a month. The suspects would then enter pleas and the trial would have to start within 90 days, Iskandar said.

The court was also informed that lawyer Jagjit Singh was appointed by the North Korean Embassy to monitor the case for them. Singh told reporters later that he was engaged to "protect the interest" of the North Korean government. He didn't elaborate.

Police have said four North Korean suspects fled Malaysia the day of the attack. Defense lawyers fear the women will be scapegoats because other people believed to have knowledge of the case left the country.
