Buenos Aires - Two people died Friday and two more were seriously injured as mobs looted supermarkets in Rosario, Argentina's third largest city, an official said.
Matias Drivet, a city hall official, gave the toll after similar violence shook other cities in Argentina on Thursday.
In Bariloche in the south, officials said looters were apparently venting anger over a blackout that had left much of Neuquen province without power on Wednesday.
People wielding sticks raided a supermarket there called Changomas, owned by the US retail giant Walmart, and stole TV sets, bicycles and electrical appliances, witnesses said.
Another supermarket was also looted.
The central government sent in army troops to restore calm.
Bariloche is a tourist city 1 650 kilometers (1 000 miles) south of Buenos Aires. - Sapa-AFP
