Two people were killed and more than 200 arrested amid an outbreak of looting in cities across Argentina, authorities said Friday.

The trouble began Thursday in the resort city of Bariloche, 1,563 kilometers (971 miles) southwest of Buenos Aires, where a mob of around 100 people assaulted two supermarkets, stealing clothes and appliances.

Eighteen police officers were injured.

Similar incidents unfolded late Thursday in six other cities, including Rosario, a major inland port northwest of the Argentine capital.

Rosario saw the worst of the violence, with two dead, two injured and 137 people arrested. Police also seized guns and vehicles packed with merchandise looted from supermarkets.

Neither the deaths nor the injuries were the result of police action, the public safety secretary in the surrounding province of Santa Fe said Friday at a press conference.

"Since last night, when street disturbances began, the order was given to the Santa Fe police chief to work ... without arms with lead ammunition," Matias Drivet said.

Campana, a town in Buenos Aires province, was the scene of attacks on two supermarkets, a gas station and cargo trucks, leading to 100 arrests.

"I don't have the information about who could be behind that, but there was someone who coordinated it," Campana municipal secretary Claudio Rodriguez told Radio 10.

Around 30 small shops were looted in Zarate, 86 kilometers (53 miles) from Buenos Aires. EFE
