The list could be used if London decided to resort to the so-called Magnitsky amendment which allowed the United Kingdom to introduce sanctions against foreign officials accused of human rights violations, the Independent newspaper reported, citing a source close to both Riyadh and London, on Friday.
The source added that the idea to draw up a Saudi sanctions list initially was a "position-paper scenario" but it was subsequently being looked at as a real possibility.
Khashoggi, known for his criticism of Saudi Arabia's policies, has recently been working for the US Washington Post newspaper. The journalist went missing in Turkey on October 2. According to his fiancee, Khashoggi was invited to the Saudi consulate in Istanbul but never left the diplomatic mission's building.
Meanwhile, The Washington Post reported that Turkey had shared with the United States audio and video recordings suggesting the journalist had been murdered in the Saudi consulate. Moreover, the outlet claimed that Saudi Crown Prince Mohammad Bin Salman Al Saud had sought to bring Khashoggi to Saudi Arabia and detain him there. Riyadh has called these claims baseless.
