Three people were killed and twenty more were injured in an accident on the road Sofia-Burgas, five kilometers off Karnobat, in the direction of Sliven. A bus, heading from the Black Sea coast resort of Sunny Beach to Sofia, crashed into a vehicle carrying propane-butane, followed by another crash into a cistern carrying petrol. Large amounts of petrol spilled out. The heavy accident has most probably been caused by low visibility, because of the thick mist. In a separate development, five kilometers off this crash a car ran into a heavy-freight vehicle, leaving three injured.
