SOFIA, Bulgaria (AP) — Human error is believed to be the most likely cause of the fiery bus crash in Bulgaria that killed 44 people, including 12 children, early Tuesday, a Bulgarian official said Thursday.
The bus, which officials said had 52 people on board, mostly nationals of North Macedonia, was one of four returning from a trip to Istanbul. Turkey. It hit a highway guardrail in western Bulgaria, caught fire and was reduced to a charred shell. Officials said the passengers were trapped as both exits were blocked.
