Rio 2016 organisers confirmed that two people suffered minor injuries when a bus transporting journalists at the Olympic Games reportedly reportedly came under attack on Tuesday.

Reports claimed that the bus was either fired upon or hit by rocks, resulting in two windows being smashed.

A statement on the Rio 2016 website confirmed the incident and said the matter is still being investigated.

"According to the driver's report, the media transport bus left the Youth Arena in Deodoro at around 19:30, Tuesday 9 August, travelling towards Barra Olympic Park." the statement said.

"When on the expressway Transolimpica, near Curicica, the driver heard a noise from inside the bus which he thought was photography equipment falling down.

"Immediately, he looked in the rearview mirror and noticed that the passengers were lying on the ground. He continued to drive for a few metres until he saw a police car and stopped.

"At this time, he realised that two windows on the same side of the bus were broken. He resumed the route under the escort of the police car and the broken windows began to give way further.

"After arriving at the Media Centre, he found that two passengers had minor injuries caused by broken glass cuts. The driver will provide a statement to police accompanied by a security manager of the Rio 2016 Olympic Games Organising Committee.

"The bus will be subjected to an official inspection by the police. Preliminary results will be released as they become available."

On Saturday a bullet landed at the feet of photographers at Rio's equestrian venue, with security forces concluding that the missile was fired at a police blimp from a local community.

A controlled explosion was also carried out on a suspect package on Saturday, close to the finish line of the men's cycling road race.
