A massive pile-up involving approximately 50 vehicles has left at least 12 people dead and 50 others injured on a motorway in eastern Bulgaria. The incident occurred on the A1 highway, which connects Sofia to the city of Burgas, during hazardous weather conditions. Authorities reported that thick fog likely triggered the catastrophe, which began when a truck and a bus collided near Yambol, leading to a chain reaction of wreckage across all six lanes of the road.

Emergency responders, including firefighters and police, worked extensively at the crash site to assist trapped survivors and transport the injured to nearby medical facilities. In response to the tragedy, Prime Minister Rumen Radev has declared a national day of mourning, while European Commission President Ursula von der Leyen cut her scheduled visit to the country short to express her condolences. The government has mobilized aircraft to assist with the evacuation of the wounded as the nation grapples with the scale of this devastating highway accident.
