Fourteen people have been killed after a storm brought heavy rain and winds of 150km/h (93mph) to eastern Argentina.
The storm hit the port city of Bahia Blanca, around 570km (355 miles) south of Buenos Aires, on Saturday, damaging buildings and causing power outages before moving towards the capital on Sunday.
It comes just a week after new president Javier Milei assumed office.
Another two people were killed in neighbouring Uruguay.
Officials said that, after landing in Bahia Blanca, the storm caused part of the roof of a sports centre to collapse during a roller skating competition, killing 13 people.
A further 14 people were injured, and firefighters at the scene had to work to free people trapped beneath the rubble.
An orange weather alert, indicating a threat to life and property, was in force in parts of Buenos Aires province on Saturday night.
Another woman was killed in the town of Moreno, a suburb of the city, when she was hit by a falling tree branch early on Sunday.
Footage published by local media and reportedly shot at the Aeroparque airport near Buenos Aires showed a parked plane being buffeted around by the winds.
