BUENOS AIRES - Heavy rains in the Argentine port city of Bahia Blanca, southwest of the capital Buenos Aires, left at least 10 dead and caused substantial flooding on Friday.

More than 260 millimeters of rain fell within a few hours, destroying bridges and causing asphalt roads to collapse, the city said, adding that more fatalities could not be ruled out.

"All available resources are being deployed with municipal teams, the provincial government, the navy and the Argentine army to provide assistance," Bahia Blanca authorities said on X.

The storm forced the evacuation of homes and health centers in the major commercial port city, some 600 km from the capital. Social media images showed mothers fleeing a flooded hospital with their newborn babies.
