A huge fire has broken out dangerously close to the "Trakia" motorway.
Photos on social media show flames near the asphalt, and the air is heavily smoky.
"There are police and a fire department at the scene. The fire is heading towards Sofia. You are driving slowly in both lanes," says an eyewitness.
The location of the fire is at km 97. The causes of the fire and whether it is localized are still unclear.
