The US government is to release a declassified intelligence report which reportedly finds the Saudi Crown Prince responsible for approving the murder of journalist Jamal Khashoggi.
Three US officials have told NBC News that in the report Crown Prince Mohammed bin Salman likely ordered the killing of the Washington Post columnist who was critical of the Saudi regime.
Mr Khashoggi disappeared in 2018 after entering the Saudi consulate in Istanbul, where he is later believed to have been dismembered.
Who is Jamal Khashoggi?
Mr Khashoggi was a long-time Saudi journalist, foreign correspondent, editor and columnist whose work has been controversial in the past in the ultra-conservative Sunni kingdom.
He went into self-imposed exile following the ascension of Prince Mohammed, now next in line to succeed his father, the 82-year-old King Salman.
Mr Khashoggi was known for his interviews and travels with Osama bin Laden between 1987 and 1995, including in Afghanistan, where he wrote about the battle against the Soviet occupation.
In the early 1990s, he tried to persuade bin Laden to reconcile with the Saudi royal family and return home from his base in Sudan, but the al-Qaida leader refused.
Mr Khashoggi maintained ties with Saudi elites and was viewed as a link between the West and the often opaque royal court.
As a contributor to the Post, Mr Khashoggi has written extensively about Saudi Arabia, including criticising its war in Yemen, its recent diplomatic spat with Canada and its arrest of women’s rights activists after the lifting of a ban on women driving.
Here is a timeline into the disappearance and death of the Washington Post columnist:

His later columns criticise the prince and the kingdom’s direction.
