MUSCAT — Four Asian nationals died from carbon monoxide poisoning after inhaling exhaust fumes inside a running vehicle in the Al Musannah Governorate in Oman’s South Al Batinah Governorate, the Royal Oman Police said on Friday.

Authorities said the incident took place in Al Musannah, where police teams responded to a report and found the four individuals dead inside the vehicle.

According to police, preliminary investigations revealed that the victims suffocated after inhaling toxic gases emitted from the vehicle’s exhaust while the engine remained running in a closed or poorly ventilated environment.

In a public safety warning issued following the incident, police urged residents not to sleep inside vehicles while engines are running or leave vehicles operating in enclosed areas, stressing that exhaust emissions can rapidly lead to fatal carbon monoxide poisoning.
