At least 15 people were killed and 18 were injured on Wednesday after a horrible crash on the iconic funicular railway in Lisbon, Portugal.

Shocking video from the aftermath shows the tram-like Gloria funicular crushed and destroyed following a derailment that left at least five of the injured in serious condition, officials said.

It is not yet known how many of those hurt are foreigners, they added, as the funicular is a popular tourist attraction.

“Lisbon is in mourning. This was a tragic accident … It’s a tragedy of the like we’ve never seen,” Mayor Carlos Moedas said.

Emergency services could be seen pulling bodies from the wreckage of the yellow-and-white electric streetcar, which was lying on its side.

Local media reported that some of the victims included pedestrians and people in cars that were flipped after the tram broke loose. Horrified eyewitnesses said they watched the runaway streetcar tear down the slope and land on top of a man walking down the sidewalk.

“It hit a building with brutal force and collapsed like a cardboard box; it had no brakes,” one woman told the Portuguese TV channel SIC. 

Five people were hospitalized in serious condition, the National Institute for Medical Emergencies confirmed in a statement. A child was also hospitalized, but was not critically injured.

Multiple foreigners were among those injured, but it’s unclear how many, the institute added. 

Other injured were trapped in the wreckage, but emergency responders managed to free them all within two hours.

The cause of the crash on the funicular, which carries more than 40 passengers at a time up and down a steep, 900-foot hillside in the Portuguese capital, remains unknown.

An overhead cable came loose along the route, causing the car to lose control and smash into a nearby building, Portuguese newspaper Observador reported.

Emergency services were called to the crash just after 6 p.m. local time (1 p.m. ET) during the evening rush hour.

Some 62 emergency service personnel and 22 vehicles were scrambled to the scene of the crash, according to the civil protection website.

None of the dead have yet been identified. There were no children killed in the crash, Tiago Augusto, head of the health ministry, said in a statement obtained by the New York Times.

Portugal’s President Marcelo Rebelo de Sousa offered his condolences to all those affected.

The publicly owned Gloria Funicular, which first opened in 1885 and was electrified 30 years later, is one of the most iconic features of the city of Lisbon.

Carris, the company that operates the tram, assured that its scheduled maintenance had been properly completed.
