Human rights activists and friends of Saudi journalist Jamal Khashoggi hold his pictures during a protest outside the Saudi Consulate in Istanbul, Turkey October 8, 2018.

Turkey has informed the United States that it possesses audio and video evidence showing that missing Saudi journalist Jamal Khashoggi was killed inside Saudi Arabia's consulate in Istanbul, the Washington Post reported Thursday.

A Saudi security team apprehended Khashoggi after he entered the consulate on Oct. 2 and then interrogated, tortured and killed him, the Washington Post reported, citing Turkish and U.S. officials with knowledge of the incident.

The newspaper said it remained unclear whether U.S. officials have seen the video evidence or heard the audio. Turkish officials, however, have provided descriptions of their contents to them, it added.

The report comes one day after the newspaper said that U.S. intelligence intercepts showed Saudi Crown Prince Mohammed bin Salman ordered that Khashoggi, a Washington Post columnist who was critical of the kingdom, be enticed to return from the United States to Saudi Arabia so that he could be detained.
