RIYADH, Saudi Arabia — Bankers kept their name tags obscured behind ties. Many tried to keep a low profile and avoided talking to the news media. But those hoping to escape any tarnish from attending Saudi Arabia’s global investment conference in the wake of a dissident journalist’s killing were foiled when the crown prince himself, Mohammed bin Salman, appeared at the summit meeting and received a standing ovation. 
 
 The unannounced appearance of Prince Mohammed, who is suspected of playing a role in the killing of the journalist, Jamal Khashoggi, highlighted the risk facing American businesses that chose to attend an event aimed at bringing together prominent global executives. The crown prince is now scheduled to participate in a panel discussion on Wednesday morning about building the region into a global economic powerhouse. 
 
 Many Western executives and government officials have canceled their appearances, including the chief executives of Blackstone Group, JPMorgan Chase, and foreign and finance ministers from the United States, the United Kingdom and the Netherlands. 
 
 [The case is eroding Saudi Arabia’s reputation, worrying allies in the region.] 
 
 Still, more than 3,000 people are attending the three-day conference this week and, on the first day, the lobby of the Ritz-Carlton buzzed as executives glided across the marble floors, sipping kiwi juice, exchanging business cards and discussing potential deals.

 U.S. Vice President Mike Pence says the death of Saudi writer Jamal Khashoggi "will not go without an American response." 
 
 Pence said CIA Director Gina Haspel is in Turkey reviewing the facts of what Pence called a "brutal murder." He offered condolences to Khashoggi's family. 
 
 Speaking Tuesday in Washington at an event hosted by The Washington Post, Pence would not elaborate on what a possible U.S. response would be. Khashoggi, a Post contributor, lived in Virginia. 
 
 Asked if the U.S. would sanction members of Saudi Arabia's royal family if they were found to have been complicit, Pence said that's a decision for President Donald Trump. 
 
 He says Trump will make a decision that reflects the values and national security interests of the nation and will "make sure the world knows the truth."

 Lawmakers in Spain have rejected proposals to halt arms exports to Saudi Arabia after a debate. 
 
 Conservative and ruling Socialist lawmakers argued Tuesday that jobs in the defense industry needed to be protected. They rejected non-binding proposals by far-left and smaller parties calling for a weapon export freeze. The pro-business Citizens party abstained. 
 
 Spain chose last month not to risk a $2.1 billion contract for five navy frigates in a job-hungry region when it went ahead with a bomb shipment to Saudi Arabia that members of Pedro Sanchez's Socialist government had tried to stop. 
 
 The prime minister is expected to brief lawmakers on the issue on Wednesday.

 Saudi King Salman and Crown Prince Mohammed bin Salman have received the family of killed journalist Jamal Khashoggi and expressed their condolences. 
 
 The royals received the journalist's son, Salah, and his brother, Sahel, at the Yamama Palace in Riyadh on Tuesday.

 Prince Mohammed has come under mounting pressure, with critics suspecting he ordered the high-profile operation or at least knew about it. Saudi authorities say they have arrested 18 suspects and dismissed senior officials.

 The leaders of Sweden and Denmark are reacting after Turkey's President Recep Tayyip Erdogan said Saudi Arabia murdered Saudi writer Jamal Khashoggi after plotting his death. 
 
 Stefan Lofven, Sweden's acting prime minister, says "it seems very credible that something terrible has happened there, something horrible." 
 
 However, Lofven refrained from commenting further pending more facts, Sweden's TT news agency reported. 
 
 In neighboring Denmark, Foreign Minister Anders Samuelsen is summoning the Saudi ambassador and said the meeting would be held "as soon as possible." 
 
 He said, "there are still a lot of unclear questions and I believe it is fair to give the ambassador the possibility to explain himself." 
 
 Samuelsen had earlier said there would be no official Danish participation in an investment conference in Saudi Arabia as "a natural consequence of the actual situation."

 Saudi Arabia said he was killed in a fistfight, but Turkish officials said the 59-year-old Washington Post columnist was attacked and killed by a 15-man Saudi team.

 Turkey's president has urged Saudi Arabia to reveal who ordered the "savage murder" of dissident journalist Jamal Khashoggi at the kingdom's consulate in Istanbul, and said the 18 Saudis suspected of carrying it out should be tried in Turkish courts. 
 
 Addressing lawmakers of his ruling party in Parliament Tuesday, Turkish President Recep Tayyip Erdogan says all those responsible for the killing must be punished regardless of rank — from the person who ordered his death to those who carried out the killing. 
 
 He asked: "where is the body of Jamal Khashoggi?" For the first time, Erdogan also confirmed that a body double of Khashoggi was used as a decoy after he was killed. 
 
 Erdogan's speech came as skepticism intensified about Saudi Arabia's account that he died accidentally in its consulate in Istanbul.

 President Recep Tayyip Erdogan said Tuesday that the Saudi officials began plotting against Khashoggi in late September, days ahead of his disappearance after he entered the consulate on Oct. 2. 
 
 Erdogan's comments contradicted Saudi accounts that Khashoggi died accidentally in a "fistfight" in the consulate.

 Saudi Arabia says organizers will be signing deals worth $50 billion at the start of a major economic forum in Riyadh. 
 
 The Future Investment Initiative forum, which began on Tuesday, is the brainchild of Saudi Crown Prince Mohammed bin Salman. It's aimed at drawing more foreign investment into the kingdom and to help create desperately needed jobs for its youthful population. 
 
 The deals will be in manufacturing, transportation and other fields. 
 
 Prince Mohammed was not immediately at the forum when it started. 
 
 The forum last year proved to be a glitzy affair that drew more international business attention to the kingdom. This year's event meanwhile has seen business leaders drop out over Khashoggi's Oct. 2 slaying.

 Turkey's foreign minister says his country would cooperate with international bodies if they were to launch an independent probe into the killing of Saudi writer Jamal Khashoggi. 
 
 In an interview with state-run Anadolu Agency, Mevlut Cavusoglu also said Tuesday that Turkey has not shared evidence concerning his death at the Saudi consulate with any country but added that there may have been "an exchange of views between intelligence organizations." 
 
 Saudi Arabia has said Kashoggi, a critic of the Saudi royal family, was killed Oct. 2 in a "fistfight" with officials sent to encourage him to return to the kingdom. Turkish media and officials say the 59-year-old Washington Post columnist was killed and dismembered by a 15-man Saudi hit squad. 
 
 Cavusoglu said: "If a request for an international investigation is made ... we would cooperate."

 The Turkish president is expected to announce details Tuesday of his country's investigation into the killing of Saudi writer Jamal Khashoggi, as skepticism intensified about Saudi Arabia's account that he died accidentally in its consulate in Istanbul. 
 
 President Recep Tayyip Erdogan has said he will "go into detail" about a case that has shocked the world and raised suspicions that a Saudi hit squad planned Khashoggi's killing after he walked into the consulate on Oct. 2, and then attempted to cover it up. 
 
 Top Turkish officials have said Turkey would clarify exactly what happened to Khashoggi and a stream of leaks to national and international media has increased pressure on Saudi Arabia, which is hosting a glitzy investment conference this week that many dignitaries have decided to skip because of the scandal.

– A photo released by the Saudi Press Agency on Tuesday shows a striking handshake—one between Crown Prince Mohammed bin Salman and the son of slain journalist Jamal Khashoggi. The crown prince is suspected of playing a role in the murder of Khashoggi, but he and his father, King Salman, are pictured greeting Salah Khashoggi at Yamama Palace in Riyadh to offer their condolences. They also greeted the elder Khashoggi's brother. A friend of Salah Khashoggi tells the AP that the journalist's son has been under a travel ban since last year. Also Tuesday, the crown prince received a standing ovation when he made an unannounced visit to his nation's Future Investment Initiative, reports the New York Times. The annual summit has a lot of big-name no-shows this year because of the Khashoggi controversy. Meanwhile, CIA Director Gina Haspel was in Turkey reviewing the investigation, and VP Mike Pence said in DC that the "brutal murder" of Khashoggi "will not go without an American response." (Turkey's president says the official Saudi explanation looks pretty shaky.)
