RIO DE JANEIRO — A powerful tornado in Brazil’s southern state of Parana killed six people and injured hundreds Friday night, state officials said Saturday. Dozens of homes were destroyed.

The tornado, which hit speeds of more than 250 kph (155 mph), prompted the government to declare an emergency in the affected region.

State officials in a statement said at least one person was missing hours after the tornado touched down. Five of the killed were adults and the sixth was a 14-year-old girl.

The government said that more than 750 people, including children and pregnant women, had received medical attention. Of those, at least 10 underwent surgery and nine remained in serious condition.

The tornado downed trees, overturned vehicles and lifted the roofs of several structures.
