Al-Aiban told the United Nations Human Rights Council in Geneva that the Kingdom has taken all necessary measures in the case of murdered journalist Jamal Khashoggi. Ultimately, the Saudi authorities have charged 11 people with Khashoggi's murder.
Khashoggi, who worked as a contributor for The Washington Post, was an outspoken critic of Crown Prince Mohammed bin Salman.
"We would like to assume that Mr. Al Aiban's remarks reflected his personal views rather than the official position of the Kingdom of Saudi Arabia - our friend and kin", the communications director said.
Khashoggi was killed and dismembered by a group of Saudi operatives shortly after he entered the consulate October 2.More news: Sanders's campaign aide apologizes for dual-loyalty remark in reference to Jews
Aiban said that there had so far been three hearings, and that the accused and their lawyers had been present.
He said the kingdom would not accept what he termed as foreign interference in its domestic affairs and judicial system.
The CIA concluded late a year ago that bin Salman ordered the journalist's assassination, an accusation that has been echoed by U.S. senators and other observers.
The human rights review coincided with reports from Yemeni military officials that the Saudi-led coalition launched airstrikes which mistakenly killed and wounded forces allied with the government, who the coalition support.More news: MLB Switches to Single Non-Waiver Trade Deadline for July 31
The suspects, he said, "were entitled to a fair trial. and none of their human rights have been violated, and they have been subjected to no form of torture or cruel and inhuman treatment". In an interview with Al Jazeera, Assiri said Aiban's refusal to allow an global independent investigation suggests officials at the highest levels "are hiding something".
