Lisbon's Elevador da Glória, a funicular line popular with tourists, derailed on Wednesday, killing three and injuring approximately 20 other people.
Two of the injured are in critical condition, with five slightly injured, CNN Portugal reported, citing an official. Emergency responders, including police and firefighters, are at the scene.
"What we can say at this moment is that there are several victims, we are not aware of any fatalities, but we are only now arriving at the scene," Paulo Sousa, shift chief of the Lisbon Fire Brigade, told Reuters.
A photo from the site seen by The Jerusalem Post showed the tram-like funicular, which carries people up and down a hillside in the Portuguese capital, practically destroyed.
A firefighter source told Observador that the incident was caused by a cable coming loose in the structure, which caused the tram to lose control and crash into the wall of a building.
Each funicular tram can carry up to 43 people.
Similar tram collisions, derailings, over recent years
Two trams collided in August 2023, injuring at least 13, according to EuroWeekly News.
A tram also derailed in February 2021, injuring at least four, The Portugal News reported at the time.
A similar incident occured in April 2019, when a tram was involved in a collision with a French-registered tourist bus, according to the Portugal Resident.
Another similar incident occured in December 2018, when one of the trams derailed and overturned, injuring 28, BBC reported at the time.
