(LONDON) — At least 16 people are dead and another 21 injured after a streetcar derailed in Portugal’s capital on Wednesday, officials said.

At least five people remain in life-threatening condition Thursday following the crash in Lisbon, according to Portugal’s presidency office.

One 3-year-old child is included in the injured, according to an official.

It appears the safety cable on the electric streetcar broke, causing the car to derail, Lisbon’s communications department said, based on preliminary information. The investigation into the cause is ongoing.

Its operator, Carris, said it complied with all maintenance protocols, including daily inspections.

The famed funicular, known as the Elevador da Gloria, travels up and down a steep hill using two streetcars.
