A packed train has crashed into the end of the track in a Buenos Aires railway station, killing at least 50 passengers and injuring more than 500 others, Argentine officials say.

The commuter train came in too fast and hit the barrier at the end of the platform at about 20km per hour, smashing the front of the engine and destroying the coaches behind it.

Wednesday's accident is one of the deadliest train crashes in the country's recent history.
