A train crash in Argentina has killed at least 49 people and left hundreds injured, according to officials.
A train collided into the end of the line at a station in the capital Buenos Aires, as hundreds of commuters attempted to go to work.
Transportation secretary Juan Pablo Schiavi said the train hit a barrier travelling around 12 miles an hour, with one carriage driven into the next. According to CNN said there could have been problems with the train's brakes.
One shaken passenger told journalists that the impact was "tremendous".
According to Alberto Crescenti, the city's emergency medical director, up to 550 people were injured.
It could be the highest death toll from a train crash in the country since 1970, when 200 people died.
