Warning: Footage in this article is graphicThe Salt Lake City Police Department has released body camera footage of a Sept. 4 incident in which an officer shot a 13-year-old boy.Videos from four officers' cameras and audio of the 911 calls from the boy's mother can be viewed above.When officers responded to the area, the mother told them her son, Linden Cameron, was "out of control" and needed to be taken to the hospital. She has publicly said that her son has autism.She told officers he may have had what she believed was a BB or pellet gun. She also told them her son had previously threatened to shoot one of her coworkers."I don't believe it's a real gun," she told officers."Unfortunately, we have to treat them all as if they are [real guns]," one officer responded, to which she replied, "Right, I know."At one point, the boy ran from officers, one of whom fired at least 10 shots as heard in the bodycam footage after ordering him to show his hands and get on the ground. The shooting occurred just after 10 p.m. near the area of 500 South and Navajo Street. It was unclear from the footage if he brandished a weapon. 1138

Walmart is retreating from Europe, merging its UK supermarket business Asda with bigger rival Sainsbury's.In return, Walmart will receive ￡2.97 billion (.1 billion) in cash and a 42% stake in the combined business, the companies said in a statement on Monday.The deal values Asda at ￡7.3 billion ( billion), and creates a mega retailer with 2,800 stores and combined sales of roughly ￡51 billion ( billion).The sale of Asda follows Walmart's exit from Germany, its other major outpost in Europe, in 2006.Walmart could use the cash to fuel its expansion in other international markets. The US retailer is reportedly close to agreeing to invest in India's Flipkart, an online retailer that has also attracted attention from Amazon."This proposed merger represents a unique and bold opportunity, consistent with our strategy of looking for new ways to drive international growth," Judith McKenna, the CEO of Walmart International, said in a statement.The combination with Asda will give Sainsbury's more firepower as it confronts digital competitors including Amazon and aggressive discount chains, such as Germany's Lidl and Aldi.It also creates a new UK market leader: Sainsbury's and Asda together control over 31% of the grocery market, according to Kantar Worldpanel. The current industry front runner, Tesco, has nearly 28%.Regulators will have a close look at the deal, but the geographical distribution of Sainsbury and Asda stores could limit concerns over reduced competition.Upmarket Sainsbury's is strong in southern England, while Asda, which tends to have larger stores and lower prices, is well represented in the north. Together, the supermarket chains employ 330,000 people.The UK Competition and Markets Authority last year approved Tesco's takeover of wholesaler Booker, saying the deal would not reduce competition in the sector, which is known for its razor-thin margins and frequent price wars. 1929

WASHINGTON (AP) — For much of the United States, invasive grass species are making wildfires more frequent, especially in fire-prone California, a new study finds.Twelve non-native species act as "little arsonist grasses," said study co-author Bethany Bradley, a University of Massachusetts professor of environmental conservation.Wherever the common Mediterranean grass invades, including California's southern desert, fires flare up three times more often. And cheatgrass , which covers about one-third of the Intermountain West, is a big-time fire promoter, Bradley said."I would not be surprised at all if invasive grasses are playing a role in the current fires but I don't think we can attribute to them directly," Bradley said.University of Utah fire expert Phil Dennison, who wasn't part of the study but says it makes sense, said, "In a lot of ways, California was ground zero for invasive grasses. Much of California's native perennial grassland was replaced by Mediterranean annual grasses over a century ago. This study doesn't look at invasive grasses in the areas that are burning in California, but invasive grasses are contributing to the fires there."Experts say the areas burning now in California are more shrubs and grasses than forests, despite what President Donald Trump tweeted over the weekend."This is a global problem," said University of Alberta fire expert Mike Flannigan, who wasn't part of the study but said it makes sense. "I think with climate change and human assistance we are moving to a grass world. One region they should have mentioned is Hawaii where wildfires are increasing in large part due to invasive grasses."Invasive species are spreading more because of climate change as warmer weather moves into new areas, said study lead author Emily Fusco, also of the University of Massachusetts. New England and the Mid-Atlantic are seeing new invasive and more flammable grasses, Bradley said.The study in Monday's journal Proceedings of the National Academy of Sciences looks at the connections between a dozen species of invasive grasses and fires nationwide, finding fires occur more often in places with the non-native grasses. But the study did not find a link between invasive grasses and the size of the fires.Four of these species, including cheatgrass and common Mediterranean grass, are in California. These grasses get dry and then watch out, Fusco said."When you start a fire normally you want kindling," Fusco said. "The grasses are, more or less, like kindling"If someone lights a match and throws in the middle of a forest, it is unlikely a fire will start, but throw it in a field of cheatgrass "and odds are that it's going to catch," Bradley said."We are the reason that invasive species are here. We are the reason that they get spread around," Bradley said.Flanagan noted that invasive plants that are not grasses also feed the wildfire problem.While most outside experts said the study was important, wildfire expert LeRoy Westerling at the University of California, Merced said that with wildfires the size is key so this study is less valuable because it measures frequency.While size matters in forest fires, study author Bradley said mid to small size fires are the ones "in everybody's backyard" and affect people and their buildings more. 3313

WASHINGTON (AP) — A vehicle collision between U.S. and Russian forces in eastern Syria has left four U.S. troops with concussions. That's according to two U.S. officials who are speaking on condition of anonymity to provide details that haven't been made public yet. It's the most violent skirmish in months between the two forces. One official says Russian vehicles sideswiped a light-armored U.S. military vehicle, injuring four Americans. The official says two Russian helicopters flew above the Americans, and one of the aircraft was within about 70 feet the vehicle. There have been several other recent incidents between the American and Russian troops who all patrol in eastern Syria, but officials describe this one as the most serious. 752
