LISBON, Portugal (AP) — The death toll from a crash involving a popular Lisbon streetcar rose to 17 on Thursday after two individuals succumbed to their injuries in the hospital, according to emergency services.

All deceased were adults, as confirmed by Margarida Castro Martins, head of Lisbon's Civil Protection Agency. Their identities have not been released pending family notification.

At least 21 people sustained injuries in the incident, including a 3-year-old child. The injured range in age from 24 to 65 and represent diverse nationalities, including Portuguese, German, Spanish, French, Italian, Swiss, Canadian, Moroccan, South Korean, and Cape Verdean.

The crash occurred around 6 p.m. local time on Wednesday when the 19th-century streetcar known as the Elevador da Gloria, which attracts numerous tourists, derailed and collided with a building. Witnesses reported hearing a loud crash, describing the vehicle as out of control.

Emergency responders quickly arrived, with all victims extricated from the wreckage within two hours. Investigators from Portugal's Judicial Police are examining the scene, focusing on the streetcar's rails and condition.

As a precaution, Lisbon's City Council has halted operations of three other funiculars for inspections. The Elevador da Gloria, inaugurated in 1885, is classified as a national monument.

Authorities have not confirmed the cause of the derailment. The government has expressed condolences, declaring a national day of mourning following the tragic incident.
