U.S. Secretary of State Mike Pompeo met Saudi Arabia's king and crown prince to discuss the disappearance of journalist Jamal Khashoggi on Tuesday and Turkey's foreign minister said the envoy would bring information about the case to Ankara.
Khashoggi, a U.S. resident and leading critic of the Saudi crown prince, vanished after entering the Saudi consulate in Istanbul on Oct. 2. Turkish officials say they believe the Saudi journalist was murdered there and his body removed, which the Saudis strongly deny.
President Donald Trump, who dispatched Pompeo to Riyadh amid strained ties with the key ally, has speculated that "rogue killers" may be responsible after speaking with King Salman.
After talks with the king, Pompeo met Foreign Minister Adel al-Jubeir and will see Crown Prince Mohammed bin Salman for a second time at a dinner. He is then expected to go to Turkey.
Overnight, Turkish crime scene investigators entered the Saudi consulate in Istanbul, the last place Khashoggi was seen before vanishing, for the first time and searched the premises for over nine hours, Reuters witnesses said.
They will continue on Tuesday, expanding their search to include the residence of the Saudi consul as well as consulate vehicles, Turkey's Foreign Minister Mevlut Cavusoglu said.
Turkish President Tayyip Erdogan, speaking to reporters in parliament, raised the possibility that parts of the consulate had been repainted since Khashoggi disappeared. "The investigation is looking into many things such as toxic materials and those materials being removed by painting them over," he said.
The case has provoked an international outcry against the world's top oil exporter, with media and business executives pulling out of an investment conference next week.
HSBC CEO John Flint backed out on Tuesday , as did the CEOs of Standard Chartered and Credit Suisse.
During the initial consulate search, CNN reported on Monday that Saudi Arabia was preparing to acknowledge Khashoggi's death in a botched interrogation, after denying for two weeks any role in his disappearance.
Cavusoglu said Turkey had "not received a confession" yet from Saudi Arabia over Kashoggi's disappearance, but added that he expected Pompeo to bring fresh information from Riyadh when he arrives in Turkey.
Turkish authorities have an audio recording indicating that Khashoggi was killed in the consulate, a Turkish official and a security source have told Reuters, and have shared evidence with countries including Saudi Arabia and the United States.
Some 10 Turkish investigators left the consulate before 5 am (0200 GMT) after searching the premises overnight, and a Turkish prosecutor departed around 1-1/2 hours later, followed shortly after by a Saudi team.
Forensic vehicles took away soil samples as well as a metal door from the garden, a Reuters witness said. A police dog was part of the search team.
"The Turkish crime scene investigators carried out searches in the consulate and took the things deemed necessary," a senior Turkish official said, after acknowledging the difficulty of collecting evidence 13 days after the alleged incident.
The U.N. human rights chief on Tuesday said immunity on diplomatic premises and officials should be lifted for the Khashoggi investigation.
Many members of the U.S. Congress, which has long had a testy relationship with Saudi Arabia, have issued strong criticism of the kingdom.
Saudi Arabia has said it would retaliate against any pressure or economic sanctions "with greater action," and Arab allies rallied to support it.
The Saudi riyal, rebounded early after falling to its lowest in two years over fears that foreign investment could shrink. Saudi stock index was down 3 percent in early Tuesday trade before it recouped some losses for a decline of 0.5 percent by 0949 GMT.
The chief executive of Clariant, which has Saudi Basic Industries Corp (SABIC) as its anchor shareholder, said rising tensions about Khashoggi could hit the Swiss speciality chemicals maker.
Khashoggi, a familiar face on Arab talk shows, moved to Washington last year fearing retribution for his criticism of Prince Mohammed.
Members of Khashoggi's family have called for "an independent and impartial international" investigation.
Khashoggi's fiancee Hatice Cengiz, who was waiting outside the consulate the day he disappeared, tweeted a Koranic verse warning those who kill on purpose, with the hashtag "Jamal is the Martyr of the Word".
A pro-government Turkish daily published preliminary evidence last week from investigators who it said had identified a 15-member Saudi intelligence team that arrived in Istanbul on diplomatic passports hours before Khashoggi disappeared. One of the names matches a LinkedIn profile for a forensic expert who has worked at the Saudi Interior Ministry for 20 years.
