A carriage on one of Lisbon's most iconic tourist attractions, the Glória funicular railway, derailed and crashed on Wednesday. The popular tram-like form of transport is designed to travel up and down steep slopes.
Portuguese authorities have confirmed 16 people were killed, revising an earlier figure which put the death toll at 17.
It is not yet clear what caused the carriage to derail, and an investigation into the cause of the accident is under way.
The carriage derailed at around 18:15 (17:15 GMT) on Wednesday 3 September, near the city's Avenida da Liberdade boulevard. More than 60 rescue personnel and 22 vehicles were deployed to the scene.
Officials say it is too early to determine what caused the crash, but reports suggest that a cable came loose along the railway's route, causing it to lose control and collide with a building.
Emergency services gave a death toll of 17 on Thursday but Prime Minister Luís Montenegro later clarified that 16 were dead, attributing the discrepancy to a duplicate registration of a victim.
Among those who died were five Portuguese, three Britons, two South Koreans, two Canadians, an American, a French person, a Ukrainian, and a Swiss national.
The Glória funicular can carry about 40 passengers and is not only a popular tourist attraction but also a crucial means of transport for the city's residents, assisting them in navigating Lisbon's hilly streets.
The country was observing a national day of mourning on Thursday while Lisbon Mayor Carlos Moedas declared three days of mourning in the capital. Global leaders have expressed their condolences, highlighting the impact of this tragic accident.
