What happened in Lisbon?
At about 6:15pm local time (17:15 GMT), a carriage on Lisbon’s world-famous funicular electric railway derailed and crashed.
Witnesses said they heard a loud noise before one of the trams sped down a steep slope in the city, apparently out of control.
“It hit a building with brutal force and collapsed like a cardboard box; it had no brakes,” a witness told the AFP
