Turkish President Recep Tayyip Erdogan has for the first time accused the Saudi government directly of murdering journalist Jamal Khashoggi.
"We know that the order to kill Khashoggi came from the highest levels of the Saudi government," he wrote in an article in the Washington Post, according to BBC report.
But stressing Turkey's "friendly" ties with Saudi Arabia, he added that he did not believe King Salman was involved. Khashoggi was murdered at the Saudi consulate in Istanbul on 2 October.
Turkish investigators believe the journalist, who was living in exile, was strangled when he visited to collect documents for his forthcoming marriage to a Turkish citizen.
His body has not been found and an aide to President Erdogan, Yasin Aktay, has said he believes it was dissolved in acid after being cut up.
The murder, initially covered up by Saudi officials, caused a diplomatic crisis between Saudi Arabia and its allies. The Saudis have since arrested 18 suspects who, they say, will be prosecuted in Saudi Arabia. Turkey wants them extradited.
A memorial service marking four weeks since the journalist's death has been held in Washington.
