He also acknowledged the resilience of Qatar's " strong economy" in a surprising shift of tone for the man who has spent more than a year enforcing an embargo against the small gas-rich emirate.
The Saudi officials who spoke to the AP acknowledged that the kingdom sent a team to Turkey, but said the men were acting on a directive issued by King Salman's predecessor, King Abdullah, to bring Saudi dissidents overseas back to the kingdom - ostensibly to take part in a "national dialogue" over the country's future.
Turkish President Tayyip Erdogan spoke to Prince Mohammed on Wednesday and the two discussed the steps needed to bring to light all aspects of the killing of Khashoggi, a presidential source said. Britain followed suit on Wednesday as France said it was ready to back worldwide sanctions against those responsible. Speaking to Parliament, May said if any Saudis named in relation to the death had visas to enter Britain they'd be revoked. That followed a similar vow from the U.S. a day earlier.
The state-run Saudi Press Agency says Saudi prosecutors are calling the killing of Jamal Khashoggi a premeditated crime.
It is not entirely out of the realm of possibility that Prince Mohammed will be removed in order to resolve the ongoing crisis.
Riyadh has blamed a "rogue operation" for the death of the prominent Saudi journalist and said the crown prince had no knowledge of the killing. He called the killing of Khashoggi a "heinous crime".
"Even if US President Trump saves (Mohammed bin) Salman, in the eyes of the world he is a questionable person with Khashoggi's blood on his hands", Cevik's column said.
But Sabah, another pro-government newspaper that has published leaks about the case from Turkish officials, said Saudi Arabia has yet to give Turkish authorities permission for a search. Erdogan, meanwhile, said those who ordered the killing should also face justice.
The statement is the bluntest to date by a figure associated with the Turkish president on the Saudi prince's involvement in the murder. However, the United States and its allies fell short of taking any real punitive measures against Riyadh.
The investment conference, nicknamed "Davos in the desert" and aimed at drumming up funds to help Riyadh diversify its oil-reliant economy, has been overshadowed by the outcry over Khashoggi's murder and a string of global business leaders withdrew from the three-day event.
Saudi officials initially denied having anything to do with Khashoggi's disappearance after he entered the consulate on October 2, before changing the official account to say an internal investigation suggested he was accidentally killed in a botched operation to return him to the kingdom. That explanation has been widely rejected as a whitewash.
