Pompeo in Saudi for crisis talks on missing journalist

US top diplomat Mike Pompeo was in Saudi Arabia for urgent talks with King Salman Tuesday seeking answers about the disappearance of journalist Jamal Khashoggi, amid US media reports the kingdom may be mulling an admission he died during a botched interrogation.

"Rogue killers" could be to blame for the disappearance of Khashoggi, who has not been seen since he walked into the Saudi consulate in Istanbul on October 2 to sort out marriage paperwork, US President Donald Trump said after telephone talks with the king.

Trump dispatched Pompeo to Riyadh for what the State Department described as "face to face meetings with the Saudi leadership".

Turkish police on Monday searched the consulate for the first time since Khashoggi, a Saudi national and US resident who became increasingly critical of powerful Crown Prince Mohammed bin Salman, went missing.

Turkish officials have said they believe he was killed - a claim Saudi Arabia has denied - with the controversy dealing a huge blow to the kingdom's image and efforts by its youthful crown prince to showcase a reform drive.

But US media reported on Monday that the kingdom is considering an admission that Khashoggi died after an interrogation that went wrong during an intended abduction.

Until Monday, Riyadh had not allowed Turkish investigators to search the consulate - officially Saudi territory - with reports both sides were at odds over the conditions.

The investigators, who arrived in a motorcade of six cars late Monday, left the premises in the early hours of Tuesday after an an eight-hour search, an AFP correspondent reported.

They took samples with them, including soil from the consulate garden that was loaded into vans, one official at the scene said.

A Saudi delegation had entered the consulate one hour before the Turkish police arrived and appeared still to be inside as the search was conducted.

Trump's comments came after a telephone conversation with King Salman, father of the crown prince, the first such talks since the crisis erupted.

"Just spoke to the King of Saudi Arabia who denies any knowledge of whatever may have happened 'to our Saudi Arabian citizen'," Trump tweeted.

Riyadh's most recent comments have focused on having no knowledge of any killing or denying any order to kill Khashoggi had been given.

"The denial was very, very strong," Trump later told reporters at the White House. "It sounded to me like maybe these could have been rogue killers. Who knows?"
