RIYADH, Oct. 25 (Xinhua) -- Saudi Arabia announced on Thursday that an investigation has been launched into Turkey's information indicating the murder of the Saudi journalist Jamal Khashoggi was "planned," Saudi Press Agency (SPA) reported.

The announcement was made by the General Attorney in a statement carried by SPA, which said the Turkish information was sent through the Joint Working Team between the two countries.

Saudi Arabia said on Saturday that 18 suspects had been arrested for links to the case of Khashoggi, who was killed after a brawl inside the Saudi consulate in Istanbul on Oct. 2.

Saudi King Salman bin Abdulaziz Al Saud later ordered the re-organization of the intelligence authorities and sacked senior intelligence officials.
