US President Donald Trump has cautioned against rushing to blame Saudi Arabia over the disappearance of Saudi journalist Jamal Khashoggi.
He told the AP news agency that Riyadh was being treated as “guilty until proven innocent”.
Trump also said that Saudi Crown Prince Mohammed bin Salman had denied knowing what happened to Khashoggi.
Unnamed Turkish officials say a search of the Istanbul Saudi consulate gave more evidence that he was killed there.
The journalist, a critic of the Saudi leadership, was last seen alive entering the consulate on 2 October. Saudi Arabia has denied killing him and initially said he left the building unharmed.
However, the New York Times reports that four of the 15 people named by the Turkish authorities as suspects in Khashoggi’s disappearance have links to the crown prince, while another is a senior figure in the country’s Interior Ministry.
According to the newspaper, one of the men has been photographed accompanying the royal on recent foreign visits.
The case has put Saudi Arabia under pressure from close allies.
