A swarm of biting fish has attacked swimmers at a popular beach in Argentina, injuring more than 70.
A 7-year-old girl had her finger partially amputated and dozens more suffered bite wounds on their extremities from the fish, a relative of the piranha called "palometas," said Federico Cornier, the director of emergency services in the city of Rosario.
"This is not normal," Cornier said on television. "It's normal for there to be an isolated bite or injury, but the magnitude in this case was great ... this is an exceptional event."
The attack happened off the popular beaches of the Parana River near Rosario, 300 kilometres north of Buenos Aires, where many Argentines were seeking relief from a heat wave over the holiday.
