(CNN) -- A tornado in northeastern Argentina killed 10 people and injured at least 45 late Monday, the state-run news agency reported Tuesday.
The nation's health minister and other government officials were traveling to San Pedro, a remote town near the border with Brazil, to offer federal assistance, the official Telam news agency reported.
The tornado caused the evacuation of dozens of homes, tore off roofs and knocked down trees and utility poles. Many homes were destroyed, officials said.
"This was not a common catastrophe," Misiones Province Gov. Maurice Closs said in a radio interview. He said reaching San Pedro was difficult because of the heavy rain and strong winds.
Misiones civil defense chief Ricardo Veselka Corrales told El Clarin newspaper that "this is the first time that something of this magnitude" has occurred in the area.
Ricardo Veselka Corrales, the Misiones health minister, said 18 of the injured were in "very grave" condition, La Nacion newspaper reported.
Local officials said they had no warning that a tornado was forming.
