Saudi Arabia’s minister of state for foreign affairs on Wednesday challenged the neutrality of a UN rapporteur’s report on the murder of journalist Jamal Khashoggi which called for an investigation of Crown Prince Mohammed bin Salman.

Adel al-Jubeir said in a statement carried by state news agency SPA that the report contained “false accusations confirmed as stemming from the preconceived ideas and positions” of UN special rapporteur on extrajudicial executions, Agnes Callamard, towards the kingdom.

He said the Saudi authorities had provided a progress report on the Khashoggi case to the UN High Commissioner for Human Rights on June 3, and retained the right to take legal action in response to the report’s claims.

Turkey’s foreign ministry on Wednesday called on all UN member states and international institutions to insist on carrying out the recommendations made in a report by a UN rights investigator on the murder of Saudi journalist Jamal Khashoggi.

Earlier on Wednesday, Agnes Callamard, the United Nations’ special rapporteur on extrajudicial executions, said evidence suggests Saudi Arabia’s Crown Prince Mohammed bin Salman and other senior Saudi officials were liable for Khashoggi’s murder.

In a statement late on Wednesday, the foreign ministry said the report confirmed the findings by Turkish authorities, while also determining that the premeditated killing was in violation of international laws and principles.
