The Saudi human rights commission rejected calls for an global investigation into Jamal Khashoggi's murder, saying they've already punished the killers who they refused to name or give any details about.
He said the kingdom would not accept what he termed as foreign interference in its domestic affairs and judicial system.
The news came as Turkey slammed attempts by Saudi Arabia to shut down an worldwide investigation into the journalist's killing.
"None of their human rights have been violated and they have been subjected to no form of torture or cruel" treatment, Aiban clarified.
"We are indeed horrified by what has happened pursuant to this unfortunate accident and we have taken those measures required for us to resolve this heinous crime", added Aiban, who headed the official Saudi delegation at the hearing.
But the responses provided by Saudi Arabia in some cases fail to match the reality on the ground, and in others reflect an unwillingness to bring national laws and practices into conformity with worldwide law.
Khashoggi's death sparked worldwide outrage and focused a global spotlight on the crown prince. Riyadh initially denied any knowledge of the killing, but later blamed rogue agents for Khashoggi's death.
On Thursday, critics of the government's handling of the investigation, including Yahya Assiri, a Saudi human rights activist, noted the omission of any mention of the kingdom's powerful crown prince. More than a month after his death, the Central Intelligence Agency concluded Salman ordered Khashoggi's death.

"They are hiding the name for the person who ordered this operation".
The notice, issued on Thursday at the request of the Turkish government, names Saud al-Qahtani, a top aide to bin Salman, as well as the country's ex-deputy army chief, Ahmed al-Assiri.
