Family members of Saudi dissident Jamal Khashoggi, who was murdered inside the Saudi consulate in Istanbul this, met with the Saudi royals on Tuesday.

Khashoggi’s sons Salah and Sahel met with Saudi King Salman bin Abdulaziz Al Saud and Crown Prince Mohammed bin Salman - commonly known as MBS - at the Yamama Palace in Riyadh. The same day, Turkish President Recep Tayyip Erdogan said his country believes the Saudis had plotted Khashoggi's death for days. A Khashoggi family friend told AP that Salah is under a travel ban.

Khashoggi, an outspoken critic of the crown prince and the Saudi government, disappeared on Oct. 2 after entering the Saudi consulate in Istanbul to receive paperwork for his upcoming wedding to his Turkish fiancee. Saudi Arabia first said that Khashoggi had left the consulate alive, but later admitted he was dead, claiming he was killed following an interrogation that “developed in a negative way, leading to a fistfight.”

The Saudi government, which has said it is conducting its own investigation, has fired five Saudi officials and arrested 18 others. On Sunday, the Saudi foreign minister Adel Al-Jubeir denied Crown Prince Mohammed bin Salman knew anything about Khashoggi's deathin the Saudi consulate in Turkey on October 2.

Erdogan, whose government claims to have audio indicating that Khashoggi was killed and dismembered by a Saudi team in the consulate, contradicted the Saudi's story in a speech Tuesday, claiming Khashoggi’s death was intentional.

“Saudi Arabia took an important step by accepting the murder. After this, we expect them to reveal those responsible for this matter. We have information that the murder is not instant, but planned,” Erdogan said.
