SAN DIEGO (KGTV) -- Several homes were evacuated and a bomb squad called to the scene after hundreds of rounds of ammo were discovered inside a Mira Mesa home Wednesday night. Authorities were called to the home on Avenida Del Gato and Valdosta Ave between 4 and 5 p.m. According to San Diego Police, a man was cleaning his deceased relative’s home when he found the ammo. Also discovered inside the home were mortar rounds and rocket rounds. Military ordnance experts, FBI and the Bureau of Alcohol, Tobacco, Firearms and Explosives were all called to the home. So far, authorities say they’re about 75 percent through the investigation. All the items discovered inside the home are so far inert, Jeff Ring, Commander of the Bomb Squad told 10News. The San Diego Fire-Rescue Department says six nearby homes had to be evacuated. A total of 14 adults and one child who live nearby had to leave. At this time, it’s unclear when residents will be allowed to return. 975

(CNN) -- Artificially-generated faces of people who don't exist are being used to front fake Facebook accounts in an attempt to trick users and game the company's systems, the social media network said Friday. Experts who reviewed the accounts say it is the first time they have seen fake images like this being used at scale as part of a single social media campaign.The accounts, which were removed by Facebook on Friday, were part of a network that generally posted in support of President Trump and against the Chinese government, experts who reviewed the accounts said. Many of the accounts promoted links to a Facebook page and website called "The BL." Facebook said the accounts were tied to the US-based Epoch Media Group, which owns The Epoch Times newspaper, a paper tied to the Falun Gong movement that is similarly pro-Trump.The publisher of the Epoch Times denied that Epoch and The BL were linked in emails to the fact-checking organization Snopes earlier this year.In a statement released after this story initially published on Friday, Epoch Times publisher Stephen Gregory said, "The Epoch Times and The BL media companies are unaffiliated. The BL was founded by a former employee, and employs some of our former employees. However, that some of our former employees work for BL is not evidence of any connection between the two organizations."The BL is a publication of Epoch Times Vietnam. As can be seen in archived pages of The Epoch Times website, Epoch Times Vietnam was no longer listed as part of Epoch Media Group in October 2018."In response, a Facebook spokesperson told CNN Business that executives at The BL were active administrators on Epoch Media Group Pages as recently as Friday morning.The dystopian revelation of the use of artificially-generated images in this way points to an increasingly complicated online information landscape as America enters a presidential election year. Silicon Valley and the US intelligence community are still struggling with the fallout from widespread online interference in the 2016 presidential election.The Facebook accounts used profile pictures that appeared to show real people smiling and looking directly into a camera. But the people do not and have never existed, according to Facebook and other researchers. The images were created using artificial intelligence technology. The same basic methods are used to produce deepfake videos — fake videos that the US intelligence community has warned could be used as part of a foreign disinformation campaign targeting Americans.Other fake accounts that were part of the same network used stolen pictures of real people, according to the social media investigations company Graphika and the thinktank the Atlantic Council. Facebook provided information to Graphika and the Atlantic Council for analysis in advance of Friday's announcement.The accounts were used to run dozens of pro-Trump Facebook groups with names like "America Needs President Trump," and "WE STAND WITH TRUMP & PENCE!," according to Graphika and the Atlantic Council.The fact-checking organizations Snopes and Lead Stories had reported in recent weeks and months about the use of artificial images on Facebook that were part of this network of accounts. Snopes published a story last week criticizing Facebook's apparent inaction on the issue. Facebook said Friday it had "benefited from open source reporting" in the takedown but said that its own systems that monitor for coordinated and inauthentic behavior had proactively identified many of the accounts.In a joint report on their findings, Graphika and the Atlantic Council outlined how they were able to determine which of the profile photos had been generated using artificial intelligence. "This technology is rapidly evolving toward generating more believable pictures, but a few indicators still give these profile pictures away," they said.Images generated using artificial intelligence, specifically by a machine-learning method known as a GAN, or generative adversarial network, are "notorious for struggling with features that should be symmetrical on the human face, such as glasses or earrings, and with background details. Profile pictures from the network showed telltales of all three."GANs consist of two neural networks — which are algorithms modeled on the neurons in a brain — facing off against each other to produce real-looking images. One of the neural networks generates images (of, say, a woman's face), while the other tries to determine whether that image is a fake or a real face.While experts were able to spot these telltale signs on close inspection, it is likely the regular Facebook user would not.Over the past year, a number of websites have emerged online that create fake faces using artificial intelligence.Researchers from Graphika and the Atlantic Council could not conclusively determine if the people behind the fake accounts had used artificial pictures from these public sites or had generated their own.In their report released Friday, Graphika and the Atlantic Council said, "The ease with which the operation managed to generate so many synthetic pictures, in order to give its fake accounts (mostly) convincing faces, is a concern. Further research is needed to find ways to identify AI-generated profile pictures reliably and at scale, so that platforms and researchers can automate their detection."Connection to Epoch Media GroupIn all, Facebook said Friday, it had removed a network of 610 Facebook accounts, 89 pages, 90 groups, and 72 Instagram accounts. About 55 million accounts followed one or more of the pages, and the vast majority of followers were outside the United States, Facebook said. Facebook did not say if all of all these followers were real — some of them may themselves have been fake accounts.The network of pages removed on Friday had spent almost million on Facebook ads, according to Facebook.Facebook's investigation primarily focused on "The BL" (The Beauty of Life) — a set of Facebook pages and a website that says its goal is to "present to the world the most beautiful aspects of life."The pages often shared pro-Trump and anti-China content.On its website, The BL outlined the dangers of "inaccurate and degenerate information" that it said "can be easily channeled toward vulnerable or uninformed people."The purpose of the fake accounts, including those using fake faces, appears to have been to promote links to The BL's website and Facebook pages, Ben Nimmo, director of investigations at Graphika told CNN Business on Friday.Facebook said the fake accounts were tied to the US-based Epoch Media Group and "individuals in Vietnam working on its behalf." The company did not outline precisely how it made the connection, but in recent years Facebook has hired a team of investigators to find fake accounts on the platform.The Epoch Times newspaper is part of the Epoch Media Group. The newspaper has almost 6 million followers on Facebook. Nathaniel Gleicher, Facebook's head of security policy, told CNN Business Thursday that Facebook was not suspending the newspaper's account but investigations into Epoch's behavior on Facebook were ongoing.Snopes reported earlier this month that the publisher of the Epoch Times denied that The BL and Epoch were linked.In August, Facebook banned ads from The Epoch Times after an NBC News investigation detailed how the newspaper was secretly running pro-Trump Facebook ads under alternate accounts. The Epoch Times' publisher said in a statement to NBC News, "The Epoch Times advertisements are print-subscription advertisements describing our paper's reporting — a popular practice of many publishers — and every one of these ads was approved by Facebook before publishing."A Facebook spokesperson said the company shared its findings with Twitter and Google, which owns YouTube.A Twitter spokesperson confirmed in a statement Friday, "today we identified and suspended approximately 700 accounts originating from Vietnam for violating our rules around platform manipulation — specifically fake accounts and spam.""Investigations are still ongoing, but our initial findings have not identified links between these accounts and state-sponsored actors," the spokesperson added.Google did not immediately respond to CNN Business' request for comment. 8341

SAN DIEGO (KGTV) -- One person was taken to the hospital with serious injuries after being struck by a car in Pacific Beach Monday afternoon. According to police, the crash happened near the intersection of Mission Bay Drive and Garnet Avenue at 1:18 p.m. Witnesses told police the silver BMW was traveling fast before hitting a 67-year-old pedestrian in a raised median along Mission Bay Drive. The car then continued into the busy intersection and hit a Ford Fusion before flipping over and coming to a stop in the Enterprise Rental lot. The pedestrian was rushed to the hospital with life-threatening head injuries, a broken pelvis and internal injuries. The 40-year-old driver of the BMW was uninjured and a woman in the Ford Fusion only had a complaint of pain. At this time, it's unclear whether or not drugs or alcohol played a role in the crash. 865

(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
