IRNA - Riyadh will never accept international investigations into the killing of the Saudi dissident journalist Turki al-Faisal, former head of Saudi intelligence said on Saturday.

According to Sputnik News Agency, during his speech at the International Peace Research Center in New York, al-Faisal said Saudi Arabia has provided all the details regarding the case and has responded to all relevant questions.

Earlier some international organizations had called Saudi investigation into slaying Jamal Khashoggi unreliable, urging an independent international inquiry into the incident.

When Riyadh admitted Khashoggi was killed inside its Consulate in Istanbul and the Saudi king ordered a probe into the issue, Rawya Rageh, a senior crisis advisor for the Amnesty international, cast doubt on the result of the investigations.

Along the same lines, the European Parliament has called for an international investigation into the murder and imposing sanctions against Saudi officials whose involvement in the murder of the prominent journalist has been proven.

The Saudi veteran writer and journalist entered the Saudi consulate in Istanbul on October second to collect paperwork for his forthcoming marriage, but ended up being murdered by senior security officials close to the crown prince.

Saudi Arabia officials initially denied all the information leaked to the media, but due to international pressure they eventually admitted he was murdered on purpose.

The whereabouts of his body remains to be known, but Turkish investigators believe the journalist's dismembered body was dissolved in hydrofluoric acid in one of the rooms of the consulate general.
