Shots have been fired at a media bus travelling between venues at the Rio Olympics.
The bus had two windows smashed as it made its way from the Deodoro zone to the main Olympic Park on Tuesday night, witnesses said.
There were no serious injuries although at least two people, named by others on board as a reporter from Belarus and a volunteer from Turkey, suffered minor lacerations from flying glass.
A media representative on board the bus said he was in shock and now just wanted to go home.
"I guess we're all lucky to be alive," he told reporters.
