Context: the pileup on the Trakia motorway, with dozens injured and 12 dead, was caused by dense fog
Before the detention, the two chain-reaction accidents on the Trakia motorway (near Yambol, at the Zimnitsa interchange) were attributed to reduced visibility caused by dense fog. More than 50 vehicles were involved in collisions in both directions, and traffic was completely blocked; the first call to 112 came at 07:10, followed shortly afterward by a second accident.
According to earlier reports, 10 people died at the scene, while two others later died in hospital. A Romanian citizen was among the injured and was receiving medical care. Crews from Yambol, Sliven, and Burgas took part in the intervention, while the authorities also mobilized a Spartan military aircraft to assist with transporting the victims.
