Rio de Janeiro - A massive fire raced through Brazil's 200-year-old National Museum in Rio de Janeiro on Sunday, probably destroying its collection of more than 20 million items, ranging from archaeological finds to historical memorabilia.
The destruction of the building, once a palace for emperors that had fallen into disrepair, was an "incalculable loss for Brazil," President Michel Temer said in a statement.
"Two hundred years of work, research and knowledge were lost."
There was no word of the possible cause late on Sunday, nor if there were casualties or the exact extent of the damage.
Firefighters in Rio did not reply to requests for comment.
