Khashoggi, a critic of Saudi rulers, was killed inside the country's Istanbul consulate on 2 October after visiting to obtain documents he needed to get married.
Even as the grisly details of Saudi journalist Jamal Khashoggi's death continues to shock the world, his sons have appealed to the authorities that they want to bury their father's body and return to the country for the objective.
Aljanobi and Zahrani, who were staying at a luxury hotel in Beşiktaş district, went to the Saudi consulate in Istanbul - where Khashoggi was killed on October 2 after he entered to collect a document he needed to marry his Turkish fiancée Hatice Cengiz - every day for a full week.
Saudi Attorney General Sheikh Saud al-Mojeb met with Turkish authorities last week in Istanbul but refused to share information from Riyadh's own investigation, according to Turkish officials.
On Saturday, Sabah newspaper, which is close to the government, said Khashoggi's body - which still hasn't been found - was dismembered and removed from the Saudi Consulate in five suitcases.
He added that the worldwide community had the responsibility to "reveal the puppet masters" behind the journalist's killing.More news: Patriots smother Bills for fifth straight win
Dubbed the "Warren Buffett of Saudi Arabia", Al-Waleed was the most high-profile among 350 suspects ─ including business tycoons and ministers ─ who were detained during a sweeping anti-corruption crackdown in the Kingdom at the Ritz-Carlton hotel.
The report also cited Turkish experts who suggested the claim that acid was used to eliminate Khashoggi's body or render it unidentifiable is likely. "This is what we are seeking answers to now", Fuat Oktay told Anadolu news agency.
Bandar Al Aiban, the head of the Saudi government delegation at the first United Nations review of the kingdom's record in five years, heard calls from other envoys for a credible investigation into the killing and for the protection of critics of the government.
"All that we want now is to bury him in Medina with the rest of his family", Salah, 33, said.
"UN member states must end their deafening silence on Saudi Arabia and do their duty of scrutinising the cruelty in the kingdom in order to prevent further outrageous human rights violations in the country and in Yemen", Samah Hadid, Amnesty International's Middle East director of campaigns, said in a statement.
"The Saudi government doesn't care about the Saudi people but they care about worldwide relations, they get their weapons from there, they get their support from there", Almoayyad said.
He said King Salman assured him that those involved in Jamal Khashoggi's murder would be brought to justice. "This will happen. Otherwise Saudi wouldn't have started an internal investigation", he said.
