Rio de Janeiro.
A huge fire has broken out at the National Museum of Brazil in Rio de Janeiro, the oldest scientific institution in the country.
Firefighters are tackling the blaze at the building, which contains more than 20 million items in its collection.
There have so far been no reports of any injuries in this fire.
The museum, which once served as the residence for the Portuguese royal family, celebrated its 200-year anniversary earlier this year.
Aerial images broadcast on Brazilian television showed how the fire, which started after the facility had closed for the day, had spread throughout the building.>
