Rio Olympics: Blast, Bullet in Troubled Start For Games

The Rio Olympics got off to a troubled start on Saturday as a loud blast erupted near the cycling race's finish line and a bullet ripped through the media tent at the equestrian venue.

Long queues also formed outside venues -- as competition went on inside -- as volunteers and security staff struggled to cope with a sudden influx of fans.

Brazilian military carried out a controlled explosion near the Copacabana finish line of Rio Olympics men's road cycling race on Saturday, witnesses said.

Military bomb disposal experts were at the scene of the explosion and kept crowds away with police.

The explosion stunned crowds gathering for the end of the race. The race leaders were about 100 kilometers (60 miles) away at the time.

Elsewhere at the Deodoro venue, onlookers were shocked when a bullet pierced the temporary venue housing media, leaving visible holes in the fabric roof and wall.

It made for an unsettling day one of the Rio Games, which were launched in a blaze of colour by the flamboyant opening ceremony.

But in further violence on Friday, police gunned down a mugger outside the ceremony venue, the Maracana stadium, and a woman was shot and killed by armed assailants near the Olympic Boulevard.

US start with a bang

The events overshadowed a busy opening day of action in which little-known American teenager Virginia Thrasher became the first gold-medallist, in the women's 10m air rifle, the first of 306 medal events.

In swimming, China's Sun Yang will defend his 400m crown and Britain's Tour de France Chris Froome was among the road race competitors.

Serbian rowers Milos Vasic and Nenad Bedik capsized in choppy waters at the Rodrigo de Freitas lagoon, while Iran's Ghader Mizbani suffered a terrifying crash in the cycling race.

At Olympic Park, the Games' hub, fans complained bitterly over transport and logistical problems which soured their experience on a sweltering day in Rio.

"We were caught like sardines in the bus and there are huge queues here," said Adriana Barbosa who travelled to Rio de Janeiro from Sao Paulo for the weekend.

Rio Olympics spokesman Mario Andrada apologised for the long queues and admitted the tournament needed to raise its game.

"Indeed we have problems on some venues especially in the Olympic Park," he said. "We apologise to everybody who is standing under the sun and in lines outside of venues.

"We need to upgrade that part of the game. We moved people from Rio 2016 to speed up the mag and bag (checks) and within the next hours we will be in much better shape."

He added: "We do hope nobody missed any important part of a competition for being on lines."

Thrasher, 19, fired the first shot for the United States when she shocked China's Du Li and Yi Siling to win the Games' first gold in the women's 10m air rifle.

"This is beyond my wildest dreams," beamed the engineering student at West Virginia University, who clinched victory on her final shot.

Golds were also on offer in weightlifting, archery, fencing and judo, while rugby made its return to the Olympic programme after a gap of 92 years.

Camille Grassineau scored the first try of the tournament -- and the first ever Olympic try in rugby's sevens format --as France's women beat Spain 24-7.
