UPDATE, 8:30 PM Pacific time: Turkish authorities have claimed they have recordings that prove journalist Jamal Khashoggi was murdered when he visited the Saudi consulate in Istanbul. The Turks have shared that information with US officials, according to the Washington Post.

The recordings were from inside the consulate, according to reports, and led the Turkish government o conclude Khashoggi was interrogated, beaten, tortured and finally killed.

Beyond the international ramifications for Saudi Arabia ’s relationships with other countries, the revelation of the tapes will likely end plans to stage a media conference sponsored by the Saudi Arabia government later this month. Many sponsors and speakers have already withdrawn because of concerns over Khashoggi’s disappearance. Refresh for updates: STX CEO Bob Simonds is the latest to withdraw from a business conference in Saudi Arabia, following the unexplained disappearance of journalist Jamal Khashoggi, who has not been seen since going to meet the Saudi consulate general in Istanbul more than a week ago.
