Outraged commuters in Argentina have set fire to a train, because they were angry about morning rush hour delays.

Images of the charred train at Merlo station, in the west of the capital, Buenos Aires, have appeared on Argentine television.

At nearby Castelar, passengers hurled stones at the ticket office and blocked the rails.

Argentina's dilapidated rail services are plagued by delays and many passengers said this latest round, caused by a broken down train, had cost them a day's work.
