A Democratic lawmaker at the US House of Representatives is reportedly planning to introduce a bill that bans Saudi Arabia from acquiring nuclear weapons in retaliation for the regime's murder of dissident journalist Jamal Khashoggi.
Riyadh is under vast worldwide pressure to explain why Khashoggi was murdered inside the Saudi consulate in Turkey's Istanbul in September.
Yasin Aktay, an advisor to Erdogan, suggested last week the body may have been dissolved in acid.
Saud al-Qahtani, a top aide for Saudi Crown Prince Mohammed bin Salman, is one of the fall guys as Riyadh tries to stem global outrage at Khashoggi's death. It then changed its narrative, saying the journalist died in fistfight.More news: Govt not seeking Rs 3.6 lakh crore from RBI: DEA Secy
"The ongoing revelations about the murder of Saudi journalist Jamal Khashoggi, as well as certain Saudi actions related to Yemen and Lebanon, have raised further serious concerns about the transparency, accountability and judgment of current decision-makers in Saudi Arabia", the letter reads.
Turkish and Saudi officials have carried out joint inspections of the consulate and the consul's residence, but Turkish President Tayyip Erdogan said some Saudi officials were still trying to cover up the crime.
A House Democrat wants to stop a major nuclear deal between the U.S. and Saudi Arabia which is now under negotiation.
Qahtani, who built up a formidable cyber army that identified dissident voices across the world and acted ruthlessly to snuff out all anti-establishment voices, became the fall guy after Turkey asserted that the Khashoggi killing was ordered by the highest echelons of the Saudi order.More news: Gigi, Bella Hadid walk together for a fashion show
On Monday, a Turkish official said Saudi Arabia sent two experts to Istanbul with the specific aim of covering up evidence after the murder.
"They also denied Turkish requests to once again search the consul-general's home, after Turks found samples of chemicals in the garden of the residence".
Turkey says Khashoggi was strangled and dismembered by a 15-member assassination squad. Ankara also seeks extradition of the suspects.
"Saudi Arabia's Attorney General Saud Al-Mojeb did not answer the question concerning the whereabouts of Khashoggi's body".More news: New Mazda3 to make world premiere at 2018 Los Angeles Auto Show
