A malfunction in a swimming pool pump at a Costa del Sol hotel has led to the hospitalisation of at least 60 tourists after toxic gas filled the air.
The incident unfolded on Sunday at an unnamed hotel in Benahavis, a town near Marbella, prompting authorities to immediately seal and close the affected swimming pool.
Holidaymakers from the UK were among those caught in the toxic release; some required urgent transfer to Marbella's Costa del Sol Hospital.
Other affected tourists received medical attention directly at the hotel site, as emergency services converged.
Children and elderly individuals prominently required treatment, demonstrating the gas exposure's broad impact.
A regional government official confirmed the circuit breaker on the pressure pump, which injects chlorine and acid into the pool, appeared to trip.
This critical fault caused the entire system to fail, halting the proper functioning of both chlorine and pH regulation mechanisms.
Despite these failures, other gases continued to release, poisoning swimmers present in the pool area.

The Andalusian government's health department explicitly attributed the incident to a system failure that resulted in a gas leakage.
Those affected reported a range of distressing symptoms, including severe vomiting, significant skin irritation, and persistent itching.
This event recalls past incidents where inadequate maintenance or faulty equipment in public facilities led to widespread public health concerns.
In 2017, a similar, though smaller, incident in a Catalonian leisure center saw several individuals treated for respiratory issues after a chemical imbalance in a spa pool.
Beyond the immediate health crisis, the aftermath of such events impacts local tourism, a vital economic pillar for regions like the Costa del Sol.
The region relies heavily on its reputation for safety and quality, attracting millions of visitors annually; tourism contributes over 13% to Spain's GDP.
Scientists at a local lab in Malaga TechPark have conducted tests, though the findings from these investigations remain undisclosed.
An official investigation into the precise cause of the leak is currently ongoing, with authorities working to ascertain the full sequence of events.
The hotel involved has declined to issue any public comment regarding the incident, maintaining silence as the inquiry proceeds.
Some of the affected individuals are now actively considering legal action against the hotel, seeking redress for their injuries and distress.
This potential legal challenge presents significant economic and reputational risks for hospitality businesses when safety protocols fail.
