At least 13 people have died in floods in the Argentine port city of Bahía Blanca.

Torrential rain forced more than 1,200 residents to leave their homes and large parts of the city have been left without electricity.

Roads and bridges were destroyed and footage shows cars piled up after being swept up by the floodwater.

On Friday more than 400mm (15.7 inches) of rain fell on Bahía Blanca, which is a third of the average total rainfall every year.
