Airlines in multiple countries have suspended the use of Boeing's new 737 MAX 8 aircraft over concerns about its safety, after an Ethiopian Airlines flight of the same model crashed Sunday killing all 157 on board.Flight ET302 to Nairobi had just taken off from the Ethiopian capital of Addis Ababa Sunday when it reported technical problems and asked for permission to turn back. It crashed shortly afterwards.As the crash investigation got underway, the Civil Aviation Administration of China ordered Monday that all domestic Boeing 737 MAX 8 jets be out of the air by 6 p.m. local time, due to its principle of "zero tolerance for safety hazards."China has one of the world's largest fleets of Boeing 737 MAX 8, operating 97 of the planes, according to Chinese state-run media.The move was followed by an announcement from Ethiopian Airlines that the carrier had grounded its fleet of Boeing 737 MAX 8 jets as an "extra safety precaution." Cayman Airways also said on Monday it was grounding both of its "new Boeing 737 MAX 8 aircraft ... until more information is received."Sunday marked the second time in less than six months that a new Boeing aircraft crashed just minutes into a flight. A Lion Air Boeing 737 MAX 8 flight went down over the Java Sea last October, killing all 189 people on board.Both crashes are under investigation and there is no evidence of a link between the two, but similarities in the incidents have prompted caution among some airlines."Given in both air crashes, the aircrafts were newly delivered Boeing 737 MAX 8, and both accidents occurred during the take-off, they share certain similarities," the Chinese administration said in a statement. It added that it would contact Boeing and the US Federal Aviation Administration to confirm "flight safety" issues before allowing the planes to fly again.Mary Schiavo, a CNN aviation analyst and the former Inspector General of the US Transportation Department, called the two incidents "highly suspicious.""Here we have a brand-new aircraft that's gone down twice in a year. That rings alarm bells in the aviation industry, because that just doesn't happen," she said.State-owned Ethiopian Airlines is one of Africa's leading aviation groups, and the continent's largest carrier by number of passengers.The Kenyan and Ethiopian governments announced a joint disaster response team on Monday to investigate the crash. Kenya's Cabinet Secretary of Transport James Macharia described it as a "very complex investigation."In a statement Sunday, Boeing said it was "deeply saddened" to hear about the loss of life in the Ethiopian Airlines plane crash."A Boeing technical team will be traveling to the crash site to provide technical assistance under the direction of the Ethiopia Accident Investigation Bureau and US National Transportation Safety Board," the statement said.Investigations ongoing after crashThe Ethiopian Airlines flight to Nairobi, in Kenya, lost contact with authorities shortly after takeoff at 8.44 a.m. local time, just minutes after it left Bole International Airport.Tewolde GebreMariam, Ethiopian Airlines CEO, said at a press conference Sunday that the pilot had reported technical difficulties and had been given clearance to return to the Ethiopian capital.An eyewitness told CNN they saw smoke coming from the plane before it crashed on Sunday.GebreMariam said a routine maintenance check hadn't revealed anything before takeoff. The pilot was a senior Ethiopian Airlines employee who had flown more than 8,000 hours and had an "excellent flying record," he added."As it is a fresh incident, we have not been able to determine the cause. As I said, it is a brand new airplane with no technical remarks, flown by a senior pilot and there is no cause that we can attribute at this time," GebreMariam said.Speaking on Monday, Kenyan Transport Secretary Macharia said relatives of the victims would be given "the utmost attention," including accommodation and flights to Ethiopia, if necessary.The US National Transportation Safety Board said on Sunday it would be sending a team of four to assist in the investigation into the crash.CNN aviation expert Richard Quest said while a "final determination" on the cause of the crash might be years away, information from the flight recorders should be retrieved within a matter of weeks.Global disasterCitizens of 35 countries were among the 157 people killed in Sunday's crash, including 32 Kenyans, 18 Canadians, nine Ethiopians and eight passengers each from China, Italy and the United States.The United Nations has announced 19 of their staff members were among the dead, including employees of the World Food Programme, the Office of the High Commissioner on Refugees and the Food and Agriculture Organization.Not all victims have been named, but some details have been released.The Ethiopian government expressed its "deepest condolences to the families," in a statement from the office of Prime Minister Abiy Ahmed. 4985

A missing Picasso painting worth million has been recovered by a Dutch art detective, 20 years after it was stolen from the yacht of a Saudi sheikh off the south coast of France.The 1938 masterpiece, entitled "Portrait of Dora Maar" or "Buste de Femme (Dora Maar)," vanished from the yacht of Saudi billionaire Sheikh Abdul Mohsen Abdulmalik Al-Sheikh while it was being refurbished in the town of Antibes in 1999.The painting previously hung in Picasso's home until his death in 1973 and depicts the artist's muse.The case baffled French police and it was feared that the artwork had been lost forever, until rumors emerged that the painting had surfaced on the Dutch black market.Arthur Brand, a renowned Dutch art detective dubbed "the Indiana Jones of the art world," said he first learned that a stolen Picasso painting had emerged in the Netherlands in 2015, but did not know which work it was.A four-year investigation ensued, which culminated in two intermediaries turning up at Brand's apartment 10 days ago with the missing painting in hand."They had the Picasso, now valued at 25 million euros, wrapped in a sheet and black rubbish bags, with them," Brand told Agence France Presse. "I hung the Picasso on my wall for a night, thereby making my apartment one of the most expensive in Amsterdam for a day," he joked.Brand discovered that the painting had been circulating the criminal underworld for numerous years, regularly being used as "collateral" and appearing "in a drug deal here, four years later in an arms deal there."He received his best lead earlier this month, when "two representatives of a Dutch businessman" contacted him, saying that their client had the painting. "He was at his wits' end," Brand said. "He thought the Picasso was part of a legitimate deal. It turns out the deal was legitimate -- the method of payment was not."The art detective pursued the lead and told the intermediaries that they had to act quickly to secure the painting in case it vanished once again into the criminal underworld.The intermediaries subsequently delivered the painting to Brand's flat, and Picasso experts from the Pace Gallery in New York flew into Amsterdam to verify it. The painting has since been handed to an insurance company, which is currently determining what to do with it.Christopher Marinello, CEO of Art Recovery International -- a law firm specializing in the recovery of stolen artworks -- told CNN that it is "highly significant and very encouraging" that insurance companies are pursuing stolen artworks long after cases have been closed. "It is great to see a work of this importance surface and not be the subject of intense litigation."He noted that it is "urgent" for anyone who has had a piece stolen to report the loss to an international database, such as the nonprofit Artive Database. That enables dealers and auction houses to be aware of whether they are handling stolen artworks."It is important to show that the market for stolen art is shrinking and that crime, in most cases, does not pay," Marinello said. He added that the robbery of precious artwork has "become an industry" for certain gangs, who "steal artworks and then ransom insurance companies.""Attempts are made by the criminals to cash out quickly. When that becomes impossible, the artwork will be traded at a fraction of its true value (less than 10%) for drugs, guns, etc. Some thieves may acquire stolen works as a sort of a 'get out of jail free' card -- to use as a bargaining chip if ever arrested. This has worked in the past with prosecutors and still works today."Still, the recovery of the Dora Maar painting is raising some questions, for instance as to whether anyone had been paid.An industry source, who requested anonymity, told CNN that a key challenge in the recovery of precious artworks is the use of payments to tipsters and informants, as this "encourages further theft.""They are just talking about intermediaries -- did the owner just hand over the painting or were payments made?"The source pointed to reports in 1999 that insurers at Lloyd's Insurance Group offered a reward of ￡350,000 (2,522) for the return of the painting intact. The current reward offered for the artwork remains unknown.Brand has recently recovered other priceless artworks, including a 1,600-year-old mosaic which was stolen from a church in Cyprus. In 2015 he also recovered "Hitler's Horses," two bronze statues made by Josef Thorak, one of two official sculptors of the Third Reich.CNN has contacted Brand with a request for comment, but has not yet received a response. 4606
