Saudi Crown Prince Mohammed bin Salman told a top aide in a conversation in 2017 that he would use “a bullet” on Jamal Khashoggi, the journalist killed in October, if Khashoggi did not return to the kingdom and end his criticism of the Saudi government, The New York Times reported on Thursday.

According to the report, the conversation was intercepted by American intelligence agencies and is the most detailed evidence to date that the crown prince considered killing Khashoggi long before a team of Saudi operatives strangled him inside the Saudi Consulate in Istanbul last October.
