Police in Argentina have arrested at least 87 people after a mob of angry commuters rioted at a train station on the outskirts of Buenos Aires.
Commuters were angered Tuesday morning when service was interrupted because of technical problems. During some five hours of violence, the rioters set fire to at least 15 rail cars and parts of the train station. They also overturned at least one police car.
Riot police fired rubber bullets to break up the crowds. At least 13 people, including policemen, were injured.
The violence comes just days before the start of the 34-nation Summit of the Americas, to take place at Mar del Plata, some 370 kilometers south of Buenos Aires.
