A fire broke out in a multi-family building in the Ronna district of Södertälje on Saturday, prompting a swift response from police and emergency services.

The blaze, which originated in the building's basement, quickly filled the stairwells with smoke, forcing residents to seek refuge on their balconies.

Emergency services used ladder trucks to evacuate the residents safely.

At least two individuals have been hospitalized, and around ten others require medical attention.

The fire, now under control, led to the evacuation of the entire building, which houses 66 residents.

Authorities have launched an investigation into the cause of the fire, treating it as a potential case of arson.

An evacuation center has been set up at a nearby school to assist those affected.
