Turkish President Recep Tayyip Erdogan on Sunday vowed to reveal within days the "naked truth" over the death of journalist Jamal Khashoggi as Riyadh insisted it did not know the whereabouts of his body and that Crown Prince Mohammed bin Salman had been unaware of any operation to kill him.
In his strongest comments to date on the affair, US President Donald Trump has accused Saudi Arabia of lying. But the Saudi foreign minister, Adel al-Jubeir, insisted on Sunday that Prince Mohammed was "not aware" of the killing and that the kingdom does not know where the body is.
Erdogan, whose ties to Saudi Arabia appear to have further soured over the Khashoggi case, said he would reveal the findings of his country's investigation into the killing in the coming days.
The Turkish leader's statement came the day after Saudi authorities conceded Khashoggi had been killed inside their diplomatic compound in Istanbul.
"We are looking for justice here and this will be revealed in all its naked truth, not through some ordinary steps but in all its naked truth," Erdogan told a rally in Istanbul.
Riyadh reacted by claiming one of the 15 had died in a car accident years ago. Saudi officials originally said Khashoggi, who stepped inside the doors of the diplomatic mission on October 2, had left unharmed, before announcing he was killed inside the building in what they described as an altercation.
The kingdom has since admitted Khashoggi died in a "brawl" inside the consulate and said it has fired five top officials and arrested 18 others in an investigation into the killing.
"Why did the 15 men come here? Why were the 18 people arrested? That should be explained in all its details," said Erdogan. Khashoggi, who would have been 60 this month, sought refuge in the United States after he fled his native Saudi Arabia following the 2017 appointment of strongman Mohammed bin Salman as heir to the throne.
