Saudi Arabia's explanation that Khashoggi was killed in a "fistfight" and 18 Saudis have been detained has been met with worldwide skepticism and allegations of a cover-up created to absolve Prince Mohammed of direct responsibility. Investigators are seeking to take statements from all 45 consulate workers within the coming days.
Jubeir called Khashoggi's killing a "huge and grave mistake", but sought to shield its powerful crown prince from the widening crisis, saying Mohammed bin Salman had not been aware.
"Saudi Arabia is a completely responsible country".
By denying any knowledge of the dissident journalist's fate for weeks, the Saudi government has forfeited the civilized world's obligation to take the polite version seriously.
As the investigation into the death of Jamal Khashoggi continues, Turkish police on Monday found a auto belonging to the Saudi consulate and bearing diplomatic plates in a private parking lot in Istanbul's Sultangazi district, where it had been parked for several days after the journalist's disappearance.
"We don't know where the body is", Jubeir said.
Saudi Arabia is also Germany's second-largest weapons customer. Trump and some of his backers have been at pains to blunt the condemnation that has been hurled worldwide at the Saudi regime, and in particular, Crown Prince Mohammed bin Salman, in whom the U.S. administration has invested much political capital.
TRT also published photographs showing Khashoggi entering the consulate wearing what appeared to be a black jacket, light gray short and gray trousers. If the supply gap created by disruption in Libya, Nigeria, Venezuela - as well as US sanctions against Iran - were to grow as large as 3 million barrels a day, Saudi Arabia would need to tap its oil reserves, he said.
Merkel reiterated her condemnation of the killing at Saudi's consulate in Istanbul, and her earlier call for the kingdom to provide further clarification on the incident and hold those responsible to account.
The joint statement stressed that the Saudis' explanation must be backed by facts.
"In a statement Sunday, the governments said attacks on journalists are unacceptable and "of utmost concern to our three nations".
Speaking late Saturday after a campaign rally in Nevada, Trump said he will be working with Congress on the U.S.' official response.
The kingdom's announcement comes two days after acknowledging that the Washington Post writer was killed October 2 at the consulate under disputed circumstances.
Turkish President Recap Tayyip Erdogan has announced he will "go into detail" about the Khashoggi investigation, including what authorities know about the 15-member "hit squad", in a special parliamentary address on Tuesday.
