Rio police release 17 hostages from a gunman on bus, two people wounded

Brazilian police said Tuesday they released 17 hostages from a gunman that took over a crowded bus in Rio de Janeiro and wounded at least two people.

Rio police said in its social media channels that all hostages aboard a bus parked at one of the city's main terminals had been freed after a successful work of negotiation led by its elite squad.

The man's motive remains unclear, Police Col. Marco Andrade said in an interview on TV news channel Globo News. We have children and older people inside the bus, Andrade said, adding that very little was known at this stage.

The bus was parked at the Sao Cristovao terminal in the city center and was scheduled to head to the neighbouring state of Minas Gerais.

Police cars and ambulances could be seen waiting near the bus, while thousands of passengers were stranded waiting for information on scheduled travel.

People interviewed on TV said they heard several gunshots, causing panic inside the crowded terminal.

One wounded person was sent to a nearby hospital, police said.
