Huong, who was photographed after the crime wearing a sweatshirt emblazoned with the letters "LOL," also said she was "not guilty" of murdering Kim.

The pair have not entered formal pleas, which will take place when the case reaches the High Court.

The charge sheet also mentioned "four others at large," who took part in the crime. Malaysian officials have previously named four North Koreans as suspects.

'Baby oil'

Aisyah thought the substance she rubbed on Kim's face was "a kind of oil, baby oil, something like that," said Andreano Erwin, Indonesia's deputy ambassador to Malaysia.

"And now the person next to me will become a (celebrity)," one friend is heard saying in the video, prompting Aisyah to laugh.

"It would be impossible for such a tiny person like her to do such a crime (as murder) if she was not manipulated," she said.

A friend who spoke to CNN on condition of anonymity agreed, saying that Aisyah was "naive" and easily "manipulated."

"Whatever that people said, she would believe. She would only follow," the friend said.

Deputy Indonesian Ambassador Andreano Erwin said outside court that he had met with Aisyah and she was "not alone."

"Indonesia will always be with her," he said.

North Korean plot

"The assassination of Kim Jong Nam was an act of systematic terror ordered by Kim Jong Un," South Korean lawmaker Kim Byung-kee said in a televised address. "The operation was conducted with two assassination groups and one supporting group."

Four North Korean suspects have been named by Malaysian authorities, with another three wanted for questioning.
