Two brothers suffocated to death in their father’s car in the Saudi city of Mecca, according to Sabq newspaper.
The boys locked themselves in the car which was parked at home under the scorching summer.
The elder brother, aged 13, is reportedly mentally retarded, and his younger brother is just three years old.
The two children were already dead when their parents found them after searching all other places.
The bodies were taken to the hospital for a post-mortem and an inquiry was launched into their deaths.
