Claims by the government of Saudi Arabia that Washington Post columnist Jamal Khashoggi died in a physical altercation inside the Saudi Consulate in Istanbul drew immediate skepticism and contradicted earlier dueling accounts from Saudi and Turkish officials.

The Saudi findings, which all but absolved the heir to the throne, Crown Prince Mohammed bin Salman, increased pressure on the Trump administration to mount an independent investigation into Khashoggi’s death.

CIA officials have listened to an audio recording that Turkish officials say proves the journalist was killed and dismembered by a team of Saudi agents inside the consulate, according to people familiar with the matter. If verified, the recording would make it difficult for the White House to accept the Saudi version that Khashoggi’s death was effectively an accident. A CIA spokeswoman declined to comment.
