Members of a team from Saudi Arabia sent to help Turkish authorities investigate the killing of journalist Jamal Khashoggi worked instead to remove evidence of the slaying, a senior Turkish official said Monday.

Secretary of State Mike Pompeo said on Thursday it would be a "handful more weeks" before the United States had enough evidence to impose sanctions on Saudi Arabia.

 U.S. President Donald Trump said on Thursday it "certainly looks" like U.S.-based Saudi journalist Jamal Khashoggi is dead.
