The report did not say why Cengiz was given police protection.
She said: "I agree with all those who say when it comes to our already limited arms exports to Saudi Arabia, that they can not take place in the current situation".
"I hope that Joe Kaeser will rethink this", the leader of the Social Democrats (SPD), Andrea Nahles, told the Bild am Sonntag newspaper on Sunday.
In a statement on Saturday, The Washington Post's publisher and chief executive, Fred Ryan, accused Saudi Arabia of repeatedly lying in the three weeks since Mr. Khashoggi's disappearance.
Her spokesman Steffen Seibert said Monday the government was still discussing internally whether ot not to bloc exports already authorised in recent months but not yet delivered.
"They made a mistake and killed Jamal Khashoggi in the consulate and they tried to cover up for it", Al-Jubeir said.
"He extended his condolences to the family of the slain journalist".
Foreign Minister Adel al-Jubeir insisted powerful Crown Prince Mohammed bin Salman was not responsible, despite multiple and conflicting accounts about Mr Khashoggi's killing on October 2. Both areas are now being searched for Khashoggi's remains. Slashing oil exports would drain revenues needed for Prince Mohammed's plans to diversify the economy, while a spike in oil prices could revive the US shale industry and lead other countries to boost production.
The crown prince has "crossed a line and there has to be a punishment and a price paid for that", Corker said. He also said he will talk soon to bin Salman, with whom his son-in-law and senior White House adviser Jared Kushner has a close relationship.
"My role as the energy minister is to implement my government's constructive and responsible role and stabilizing the world's energy markets accordingly, contributing to global economic development", Falih said. The deal "will allow us to intervene to rebalance the market in any appropriate time from January onward", he said.
Oliver Sprague, Amnesty International UK's arms expert, said: "By backing continued arms sales to Saudi Arabia, Dominic Raab is wilfully ignoring the risk of these weapons fuelling further human rights violations in Yemen".
Saudi Arabia has provided a shifting account of what happened to Khashoggi. But in an interview with The Post late Saturday, Trump conceded that there had been "deception". All of them shield King Salman and his son and from any involvement.
The UK, France and Germany said on Sunday that Saudi Arabia's version of Khashoggi's death needs to be supported by "facts" to be considered "credible".
They stressed that more efforts are needed in order to establish the truth, and added that they reserve judgment until they receive further explanation.
Turkish authorities nearly immediately concluded that Khashoggi was targeted by a 15-man squad of Saudi agents who killed and dismembered him in the diplomatic mission. "The assassination team then killed Khashoggi after the conversation ended".
Turkish president Recep Tayyip Erdogan and the United States president Donald Trump have discussed Khashoggi case and Syria situation in a phone call, media reported.
