(CNN) -- An American graduate student, who had been held for three years in Iran on suspicion of being a spy, has been freed and is headed to an American military base in Europe.Chinese-born Xiyue Wang, a Princeton University PhD student, was conducting research in Tehran when he was arrested there on espionage charges in August 2016. Wang was sent to Iran's notorious Evin Prison and sentenced to 10 years.Iran's Foreign Minister Javad Zarif said Saturday that Wang's release comes as a prisoner swap between the two countries. In exchange for Wang's release, the US freed Iranian scientist Massoud Soleimani, Zarif said on Twitter, sharing a photo of himself accompanying Soleimani home on an Iranian plane. Soleimani, an Iranian stem cell scientist, was arrested by US law enforcement upon landing in Chicago in fall 2018, according to Iran's state-run Press TV.Zarif said Soleimani and Wang would be "joining their families shortly."Because the US and Iran do not have diplomatic relations, the Swiss government had provided consular services to Wang and reported back to the State Department.The White House announced Wang's release in a statement early Saturday, thanking the Swiss for their assistance in negotiating with Iran. US officials have not replied to CNN's request for comment regarding Iran's claim of Soleimani's release."Freeing Americans held captive is of vital importance to my Administration, and we will continue to work hard to bring home all our citizens wrongfully held captive overseas," President Donald Trump said in a statement.Wang was headed to a US base in Europe and then eventually will travel back to the US after being freed from an Iranian prison, a source familiar with the matter told CNN. The source did not provide details about the location or the reason for the stop at the base, but in past instances Americans who have been held overseas in foreign detention have been taken to such locations for a medical evaluation. The source could not say how long he might spend at the base before returning to the US.Wang was flown on a Swiss government airplane to Zurich from Iran, a different source familiar with the matter confirmed to CNN. Brian Hook, the State Department's special representative for Iran, met him in Zurich, the source confirmed.The New York Times first reported the details of the Zurich arrival.'He was simply a scholar'Wang was born in 1980 in Beijing and immigrated in 2001 to the US, where he became a naturalized citizen in 2009. Wang's wife, Hua Qu, and his young son, Shaofan, are Chinese citizens.Wang is a student of late 19th and early 20th century Eurasian history, according to Princeton University. With funding from the university, Wang went to Iran to study Farsi and conduct scholarly research for his dissertation.Before traveling to Iran, Wang laid out his research plan in letters to the Pakistani Embassy in Washington, DC, which issued his visa."He was not involved in any political activities or social activism; he was simply a scholar trying to gain access to materials he needed for his dissertation," the university says.Iran accused Wang of being "sent" by Princeton to "infiltrate" the country, charges which the university says are "completely false."In 2018, a United Nations panel on arbitrary detention said that there was no legal basis for Wang's arrest and imprisonment, and called for his immediate release.'Bargaining chip'In August, three years after he was imprisoned, Wang's wife, Hua Qu, issued a plea for Trump and the international community to help free her husband."My husband is an academic researcher. He's a father, husband. He is not a political figure and he is definitely not a spy," Qu said at at the National Press Club in Washington, adding that she felt Wang was being used as a "bargaining chip" in a "geopolitical dispute" between the US and Iran.While Qu said at the time that she was in regular contact with the State Department, including Special Presidential Envoy for Hostage Affairs Robert O'Brien, she was looking for the administration to do more. She referenced the fact that Trump had dispatched O'Brien to Sweden on behalf of A$AP Rocky, noting that the arrested rapper "quickly got released."On Saturday, Qu celebrated her husband's release, saying in a statement: "Our family is complete once again. Our son Shaofan and I have waited three long years for this day and it's hard to express in words how excited we are to be reunited with Xiyue."After news of Wang's release broke, Secretary of State Mike Pompeo wrote on Twitter Saturday that the US would "not rest until we bring every American detained in Iran and around the world back home to their loved ones." 4708

(AP) — For the first time, Airbnb is taking legal action against a guest for violating its ban on unauthorized parties. The San Francisco-based home-sharing company is initiating legal proceedings against a guest who held an unauthorized party at a home in Sacramento County, California, last weekend. Three people were shot and injured at the party. Airbnb wouldn’t release the guest’s name but says it has removed the guest from its platform. Airbnb has been trying to clean up its image as it prepares for an initial public offering of its stock. The IPO, which was delayed by the coronavirus pandemic, could still take place later this year. 653

 The New York City Police Department released surveillance video Thursday of a man, later fatally shot by police, pointing a silver object at residents as if he were brandishing a gun.The video also shows 911 call transcripts of neighborhood residents who reported the man to police.On Wednesday, police shot and killed the black man, identified as Saheed Vassell, in Brooklyn after he pointed what officers believed was a gun at them, authorities said.After the shooting, officers discovered that the object was "a pipe with some sort of knob on it," Chief of Department Terence A. Monahan said at a news conference.Vassell's death comes amid a resurgence of questions about law enforcement's unequal treatment of people of color following another police shooting recently in Sacramento, California. Police there said they thought Stephon Clark had a gun, but only a cell phone was found near his body.New York's attorney general opened an investigation Thursday morning into Vassell's death, said Amy Spitalnick, a spokeswoman for Attorney General Eric Schneiderman."We're committed to conducting an independent, comprehensive and fair investigation," she told CNN.New York City Mayor Bill de Blasio said Thursday the city will be "as transparent as we can in this situation."He also hypothesized what might have happened if the man actually did have a gun."Let's play out the scenario had it been different," he said. "If this individual with a loaded weapon, who for whatever reason, including a mental health challenge, was ready to use it, that's a split-second matter of trying to save lives right then and there."How you get the full facts of what the person has in their hand, and what their mental health condition might be, and are they known to anyone, in something that's playing out in seconds and minutes, that's a very tall order," de Blasio said.'Two-handed shooting stance'The incident started shortly before 5 p.m. Wednesday when officers received 911 calls of a man aiming what callers described as a silver firearm at people in Brooklyn, Monahan said."Three different 911 callers described a man with a gun, pointing it at people on the streets," he said.When officers arrived at the scene, they found a man matching the description provided by the callers, Monahan said."The suspect then took a two-handed shooting stance and pointed an object at the approaching officers, two of whom were in uniform," he said.Four officers discharged their weapons, striking the man, Monahan said. Then they gave him first aid and called for an ambulance to take him to the hospital, where he was pronounced dead."It appears we fired 10 rounds between the four officers," Monahan said. The unidentified officers, who were not wearing body cameras, discovered the metal pipe at the scene.911 transcripts releasedIn transcripts released Thursday by New York police, 911 callers appeared somewhat uncertain about what object Vassell was holding."There is a guy in a brown jacket walking around pointing -- I don't know, (to someone else) what is he pointing in people's face? They say it's a gun, it's silver," one caller said, according to a police transcript."There's a guy walking around the street, he looks like he's crazy, but he's pointing something at people that looks like a gun and he's like popping it, as if, like if he's pulling the trigger," another caller said.A third caller said the man is holding a gun.De Blasio emphasized that 911 dispatchers and police were responding to those fear-filled reports."If that's what officers were responding to in real time, we've got to recognize that if they believe they are dealing with an immediate matter of life and death to the people in the surrounding area, that's an exceedingly difficult, tense, split-second decision that has to be made," he said.By state law, the attorney general is appointed as a special prosecutor to oversee investigations into and prosecute matters related to incidents in which unarmed civilians die during interactions with police or incidents in which there is significant question as to whether the civilian was armed and dangerous, Spitalnick said, citing the law.'He's polite ... kind'Brooklyn resident Eric Vassell told CNN affiliate NY1 that the victim was his 35-year-old son, Saheed.Saheed Vassell had no access to guns and suffered from bipolar disorder, his father told the station."He's polite, nice, he's kind. He just comes and he goes," his father said.Mayor Bill de Blasio said his understanding was that Vassell had mental health issues."What I understand is the family members have already said publicly this is someone who had a profound mental health problem, was not on medication, hadn't been on medication," he said.Renewed calls for police reformPublic fury over the shooting deaths of people of color by law enforcement, which gained traction through the Black Lives Matter movement, swelled again last month after police in Sacramento killed Stephon Clark, an unarmed, African-American father.In light of Clark's killing, which sparked weeks of protests, California lawmakers have proposed a drastic change that would limit the scenarios in which police officers can use deadly force. The bill would replace the "reasonable force" rule with a stricter "necessary force" standard.The proposal also would establish that a homicide by an officer is "not justified if the officer's gross negligence contributed to making the force 'necessary,'" according to the proposal. 5550

 President Donald Trump's attorney Jay Sekulow announced Sunday that Joseph diGenova and Victoria Toensing will not join Trump's legal team for the Russia probe."The President is disappointed that conflicts prevent Joe diGenova and Victoria Toensing from joining the President's Special Counsel legal team. However, those conflicts do not prevent them from assisting the President in other legal matters. The President looks forward to working with them," Sekulow said in a statement.The announcement on Sunday came as Trump insisted on Twitter he was not having a hard time assembling a legal team for the Russia probe, and after CNN reported on Friday that diGenova and Toensing's roles in the legal team were still in question.Two sources previously told CNN that there was concern about diGenova and Toensing's conflicts. The pair make up a husband-and-wife legal team, and two sources noted that Toensing represents clients who are connected to the special counsel probe led by former FBI Director Robert Mueller.Sekulow announced last Monday?that diGenova would be joining the legal team, and sources told CNN that both diGenova and Toensing met with Trump on Thursday. That same day, Trump's lead lawyer, John Dowd, resigned from Trump's personal legal team in the Russia investigation.The possibility of diGenova's hire attracted widespread attention to the legal figure's brash comments about the Russia investigation, including the assertion that Trump had been "framed" by FBI and Justice Department officials. 1559

(CNN) -- Easter Island has long been a bucket list destination for travelers from around the world.But the very thing that keeps the island's economy going strong may be the thing that ultimately causes its ruin: mass tourism.Recently, a spate of bad behavior by travelers on Easter Island, which is famed for its enormous statues known as moai, has spurred new conversations about how visitors to the island should behave.Specifically, a new trend of photos where people make it look like they're "picking the noses" of the moai.Jo Anne Van Tilburg is an archaeologist, director of the Rock Art Archive at the University of California - Los Angeles and the Director of the Easter Island Statue Project.Although her life's work has been to protect and study the moai, these days she's focusing more on educating the hundreds of thousands of people who visit Easter Island on how to behave properly -- on a personal level as well as an environmental one."Because of the ubiquitous nature of photography in our community, people take the same picture repeatedly. Once one person picks a nose of the moai, you can be sure there will be multiple thousands [of photos], because people are lemmings," Von Tilburg tells CNN Travel.Two other examples of these "overdone" photos are people who make it look like they're holding the Great Pyramid of Giza in the palm of their hand and travelers making it look as if they're pushing the Leaning Tower of Pisa up to keep it from falling."There's nothing creative or interesting or humorous about it. The herd instinct is real."Van Tilburg first visited Easter Island, which is part of Polynesia but a territory of Chile, in 1981 as a doctoral student. The island did not get added to the UNESCO World Heritage list until 1995.Since then, she has returned regularly and noticed a shift in the kinds of people who choose to visit Rapa Nui National Park.In the 1980s, between 2,000 and 5,000 travelers per year came to Rapa Nui National Park. These days, it's north of 100,000 annually. Instead of two flights a week from Santiago, there are three a day.That's a huge burden on an island with only about 6,000 full-time residents, not to mention one where water and other natural resources are in limited supply and must be used carefully.Although visitors in the past were able to roam the national park freely and get close to all the moai, the crush of overtourism has come with restrictions and now travelers must stick to a prescribed path and only view a few of the statues.And bad behavior is sadly not a new invention. In 2008, a Finnish man who climbed one of the moai and chipped a piece of ear off was arrested, fined ,000 and ordered to leave the island and never return.Van Tilburg also feels that there has been a shift between people who were longtime fans of archeology and history who saved up to afford a once-in-a-lifetime trip to Easter Island, to people who are simply "collectors of places."In 2018, some controls were put into place to protect Easter Island. Now, foreigners and Chileans who are not Rapa Nui can only get 30-day travel visas instead of the previous 90-day ones.So, if you still want to visit Easter Island and want to show respect for the people and the land there, what can you do? Van Tilburg has a few suggestions."Read and prepare," she says simply. "Once you show your guide you have a serious interest, they will take you seriously. Make your questions deserving of answers."And studying up on Easter Island also means recognizing that it's a living site, not a museum."There are 1,000 statues and there are 5,000 people," Van Tilburg says. "Their faces are just as important." 3669
