A train crash at a station in the Argentine capital, Buenos Aires, has killed 49 people with at least 600 more injured, officials say.
The train slammed into the barrier at the end of the platform at the Once station during the morning rush hour.
"We assume that there was some fault in the brakes", Transportation Secretary JP Schiavi said.
Eyewitnesses said the train was travelling fast. Dozens of people remain trapped.
