A fire broke out in the Haramain high-speed rail station in Saudi Arabia's coastal city of Jeddah, the country's civil defense service said on Sunday.
Five people were taken to hospital, the Makkah regional government said.
It added that 16 medical teams were working at the scene.
The 6.7 billion euro ($7.3 billion), 450 km (280 mile) Haramain Railway linking the holy cities of Makkah and Madinah, with the Red Sea coastal city of Jeddah, was opened in September last year.
