“If the assassination of Jamal Khashoggi is proved, I invite all walks of life in Saudi Arabia to cooperate in a legal measure and change the political system through civil disobedience,” Farhan al-Saud wrote on his twitter page on Monday.
He proposed the Saudi people pave the ground for transferring power to Ahmed bin Abdulaziz, the Saudi King Salman’s younger brother who is in exile in Britain, and form a new government based on the constitution.
Turkish officials said they had concrete evidence missing Saudi journalist Jamal Khashoggi was murdered, with a friend of the prominent writer saying they think he might have been dismembered.
A contributor to The Washington Post, Khashoggi has not been seen since Tuesday last week, when he entered the Saudi consulate in Istanbul, Turkey, to collect papers for his upcoming wedding.
Saudi officials said he left shortly afterwards but his fiancee, who was waiting outside, said he never came out.
Khashoggi, 59, who was once close to the Saudi royal family and has served as an adviser for senior Saudi officials, left the country last year to live in the US in self-imposed exile, saying he feared retribution for his criticism of Saudi policy in the Yemen war and its crackdown on dissent.
Turan Kislakci, a friend of Khashoggi and the head of the Turkish-Arab Media Association, said that Turkish officials said the journalist has been brutally murdered.
“What was explained to us is this: ‘He was killed, make your funeral preparations’,” Kislakci said.
“We called a few other places, these are lower officials, but they said: ‘We have evidence he was killed in a barbaric way, we will announce it tomorrow or the day after’.”
Kislakci also alleged, based on conversations with officials he did not name, that Khashoggi was made to “faint”, then was dismembered.
