Angry commuters torch trains in Buenos Aires

Angry commuters have set fire to train carriages outside the Argentine capital Buenos Aires after morning rush hour delays.

The trouble began when a malfunctioning train came to a stop before the western station of Castelar.

Angry passengers got off the train and walked along the tracks to the station, where some of them destroyed ticket machines and vandalised shops.

Meanwhile, other passengers set fire to the front carriage of the train.

In a separate incident at three stations further west, rioters set fire to another six train carriages.

The Buenos Aires police chief says there is no way the incidents are entirely spontaneous and suggests the involvement of organised violent groups.
