RIO DE JANEIRO -- Military police in Rio de Janeiro are stepping up security at the Olympics after a bus carrying journalists had two of its windows shattered by a projectile and a bullet flew into the stables area of the equestrian venue.Two large windows on the media bus were shattered Tuesday by what Rio organizers said was a rock. But a passenger disputed the account, saying she was sure it was gunfire. There were no serious injuries.Security has been a major concern surrounding the Olympics as Rio is plagued by rampant crime, including frequent murders, gun battles and muggings. Police near the Olympic beach volleyball venue in Copacabana found body parts on the shore last month, and an off-duty bodyguard for Rios mayor was shot to death around the same time in an apparent mugging. Adding to the anxiety is terrorism fears about Islamic State.Rio is deploying about 85,000 soldiers and police to secure the games, twice as many as London did four years ago. Soldiers in military fatigues and carrying guns have been a common sight around Olympic venues.Security was visibly increased overnight on a media bus route toward a womens basketball arena, with three military vehicles and more troops holding guns along the way.The equestrian venue has had two brushes with stray gunfire since the games started. As a result, officials are adding more security at the venue.A bullet flew through the roof of a media tent at the Olympic Equestrian Center on Saturday. Officials said it had been fired from a hillside slum, and that the intended target was probably a security camera on a blimp.A second bullet hit Wednesday near the stables around the same time investigators were arresting someone in the slum in connection with the first shooting. No one was injured in either episode.I can guarantee your total safety, said Gen. Luiz Ramos, chief commander for the first division of the Brazilian army. We have reinforced security systems ... to provide more security.The entire competition venue is situated on military land and gunshots could be clearly heard throughout the day during the dressage competition. Riders said they and the horses were not bothered by the noise, but Ramos said authorities ordered a halt to the training exercises.Newton de Oliveira, an independent security expert with no ties to the organizers, said the fact remains that Rio is still a violent city despite the beefed-up patrols.The level of violence is the same despite the deployment of forces, he said. You can see that areas downtown and near the beaches -- the security forces have made crime drop some, but the city in general is just as dangerous.Passenger Lee Michaelson described a panicked scene on the media bus as the glass shattered and people ducked for cover. Michaelson insisted she heard gunshots.I know what a gun sounds like, said Michaelson, who identified herself as a former Air Force officer covering the games for a womens basketball website. It was the sound before I ever saw the glass (shatter) or anything.Rio police were adamant that it wasnt gunfire, and they expressed confidence in their ability to get to the bottom of what happened.There were no shots, the forensics were made on the bus, I have pictures and I can show them, said Rio police Investigator Carolina Salomao. If there were a shot it would have gone through. There was not that so that theory has been completely discredited.---AP writer Adriana Gomez Licon contributed to this report.---Stephen Wade on Twitter: http://twitter.com/StephenWadeAP .His work can be found at http://bigstory.ap.org/content/stephen-wadeWholesale Jerseys Review .

Wales v Serbia (Saturday, 7.45pm, live on Sky Sports 1)Its a big bonus for Wales having Aaron Ramsey back. Anybody could see in the north London derby that his energy levels were great considering his injury problems. Gareth Bale and Wales host Serbia on Saturday Serbia are difficult though. Theyre a strong physical side that are dangerous on the counter-attack. Aleksandar Kolarov is their danger man going forward for me with his set-pieces.However, I think that Wales trio of Gareth Bale, who is in great form, Ramsey and Joe Allen, who is also doing well at Stoke, should see them throughCharlie predicts: 2-1 and Ramsey to score first (50/1 with Sky Bet) Wales vs Serbia November 12, 2016, 7:15pm Live on Get Sky Sports Get a Sky Sports pass Austria v Republic of Ireland (Saturday, 5pm, live on Sky Sports 1)This is a tough game, although the thing about Austria is theyre lacking a star name and you can frustrate them.ddddddddddddI always feel like Martin ONeill is an attacking manager that looks for weaknesses. The Republic of Ireland are strong defensively as well with Roy Keane instilling the discipline. Martin ONeill and the Republic of Ireland go to Austria A guy who doesnt impress me a lot of the time for his club but is great for his country is James McClean. He is that annoying player that just pops up at the back post and is always there to feed off the scraps.Wes Hoolahan is the one that has the quality though. Hes taken a long time to really be a big part of the Ireland set-up but is delivering on a regular basis now.Charlie predicts: 0-1 and Hoolahan to score (60/1 with Sky Bet) Austria vs Rep Ire November 12, 2016, 4:45pm Live on Get Sky Sports Get a Sky Sports pass Also See: No experience necessary!
