Three British nationals were killed in the Lisbon funicular crash, Portuguese police have said.

The Glória funicular, a popular tourist attraction, derailed and crashed into a building on Wednesday, killing 16.

More than 20 people were also injured, with five in a critical condition.

Nationals of Portugal, South Korea, Switzerland, Canada, Ukraine, France, and the US are also among the dead, police said.

It is not known what caused the crash. The capital’s public transport operator, Carris, said all funiculars would be inspected and that it had launched an independent investigation.

The 140-year-old carriage derailed at around 18:15 local time (17:15 GMT) near the city’s Avenida da Liberdade boulevard.

More than 60 rescue personnel raced to the scene to pull people from the wreckage.

Videos and images of the site showed an overturned, crumpled yellow carriage lying on the cobblestone street.

Portugal’s Prime Minister Luís Montenegro called the crash “one of the biggest human tragedies of our recent history” and a national day of mourning was declared.
