Jamal Khashoggi, the Washington Post columnist who has not been seen publicly since he entered the Saudi consulate in Instanbul earlier this month, was drugged, beaten, killed and dismembered by Saudi operatives in the presence of a top Saudi diplomat, The Wall Street Journal reported late Tuesday, citing Turkish officials.

A pro-government newspaper in Turkey also says it obtained recordings indicating the journalist was tortured in the office of Mohammad al-Otaibi, Saudi Arabia’s consul general in Istanbul.

U.S. Secretary of State Mike Pompeo has declined to say whether he learned Khashoggi’s fate following apparently friendly talks with the country’s royal family on Wednesday. 

Pompeo told reporters as he departed Riyadh that neither side would talk about the “facts” of the case before Saudi officials were able to complete a “thorough investigation” into the journalist’s disappearance. He claimed that the country’s leaders “made no exceptions on who they would hold accountable.”

The incident has put immense pressure on the Trump administration ― including from Republicans ― to take action.
