A massive fire has ripped through Brazil's 200-year-old National Museum in Rio de Janeiro , probably destroying its collection of more than 20 million items, ranging from archeological finds to historical memorabilia.
The cause of the fire, which broke out around 2230 GMT, is not yet known, according to local media.
Television footage showed the building engulfed by a raging blaze that firefighters have still not brought under control.

The museum was founded in 1818 by King Joao VI and is among Brazil's most important, with valuable national treasures inside.
It houses several landmark collections, including Egyptian artifacts and the oldest human fossil found in Brazil and more than 20 million artifacts.
"This is a tragic day for Brazil," President Michel Temer said in a statement.
"Two hundred years of work and research and knowledge are lost."
"This is a cultural tragedy," the director of the National History Museum said on Globo TV.
There is no word of the possible cause or if there were casualties or the exact extent of damage.
The museum had suffered from years of neglect under numerous governments, the institution's vice-director the Globo TV network on Sunday night.
"We never got anything from the federal government," official, Luiz Duarte said.
"We recently finalised an agreement with (state-run development bank) BNDES for a massive investment, so that we could finally restore the palace and, ironically, we had planned on a new fire prevention system."
In a statement posted on its website in June, BNDES agreed to financing of 21.7 million reais to "physically restore the historic building" and also to carry out work to "guarantee more security to its collections."
