A member of the hit squad that targeted Jamal Khashoggi walked out of the Saudi consulate wearing his clothes and a fake beard after he was tortured, killed and dismembered, according to CNN, which aired surveillance video of the man.
Kushner has cultivated a close relationship with Saudi Crown Prince Mohammed bin Salman, the kingdom's de facto leader.
This comes a day after Riyadh's statement that Khashoggi was killed during "a rogue operation" by individuals operating outside the scope of their authority, who tried to cover up his death.
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.
Over the weekend, German Chancellor Angela Merkel said her country would suspend arms sales to the kingdom.
Meanwhile, Turkish President Recep Tayyip Erdogan said that he will make statements about the murdered journalist during his party's parliamentary group meeting on Tuesday.
Other senior German politicians, including foreign minister Heiko Maas and foreign affairs committee chairman Norbert Röttgen, have also called for a halt in arms sales to Saudi Arabia, citing dissatisfaction with Riyadh's explanation of how Khashoggi died inside the Saudi consulate in Istanbul.
Following a telephone conversation between Saudi Arabia's King Salman and Donald Trump, the USA president told reporters that the king had denied all knowledge of Khashoggi's disappearance.
A leading Republican US senator said he believed the crown prince was behind the killing, adding that the Saudis had lost credibility in their explanations of his death. Turkish sources say authorities have an audio recording purportedly documenting Khashoggi's murder.
Britain, Germany and France issued a joint statement condemning the killing of Khashoggi, saying there is an "urgent need for clarification of exactly what happened".
Saudi authorities have said Khashoggi died in an "altercation" with Saudi officials at the Saudi Consulate in Istanbul on October 2. "The time for hollow rhetoric is over and it can not be business as usual with Saudi Arabia".
After weeks of denying knowledge of Khashoggi's whereabouts, Riyadh admitted that he had been killed in the consulate.
Jubeir said the Saudis did not know how Khashoggi, a Saudi national and U.S. resident, had been killed or where his body was.
Saudi Arabia today said that it had no plans to repeat its harsh 1973 oil embargo, even as relations with the West sour following the killing of Khashoggi.
The office of the Turkish presidency said early Monday that Erdogan and President Donald Trump had spoken by phone the night before and had agreed to "clear up the Jamal Khashoggi incident".
Falih said Saudi Arabia would soon raise output to 11 million barrels per day (bpd) from the current 10.7 million.
"I am not satisfied until we find the answer".
It has also blown up into a major crisis for Prince Mohammed whose image as a modernising Arab reformer has been gravely undermined. "And I think we're inching our way there".
