A bus carrying Saudi tourists caught fire on its way to Istanbul.
The travellers were proceeding on the Orhan Gazi highway when the driver suddenly noticed thick smoke coming out of the engine area.
The alert driver stopped the vehicle by the side of the road and disembarked all passengers before the bus eventually caught fire.
Emergency services were immediately dispatched to the scene and they managed to put out the flames.
Luckily, no injuries were reported and the passengers were transported on a different bus.
An investigation has been launched to determine the cause of the blaze.
