A 42-year-old man from Elhovo has died in hospital in Burgas, days after he was hurt in the pile-up on the Trakia motorway. The death toll is now 13.
He had several operations, one of them lasting more than 10 hours. Doctors did all they could, but he died of severe injuries.
Two other injured people are still in a serious condition. One of them is a Romanian citizen in a coma.
The crash happened four days ago and involved many cars. Besides those who died at the scene, dozens of people were hurt. They were taken to hospitals in Burgas, Sliven and Yambol, where doctors are fighting to save the most serious cases.
