Antonio Guterres, Secretary-General of the United Nations, is "deeply troubled" by Riyadh's confirmation of Khashoggi's death, according to a spokesperson.

"The secretary-general is deeply troubled by the confirmation of the death of Jamal Khashoggi. He extends his condolences to Mr. Khashoggi's family and friends," Guterres's office said in a statement.

"The secretary-general stresses the need for a prompt, thorough and transparent investigation into the circumstances of Mr. Khashoggi's death and full accountability for those responsible."

After entering the Consulate General in Istanbul on October 2, the Saudis claimed that Khashoggi, who was never heard of, "died as a result of a fight in the consulate building." (ILKHA)
