Two Ukrainian nationals were killed and at least 16 others injured when a passenger bus crashed in Bulgaria near the border with Türkiye on event date 2026-04-22, according to reporting cited by Ukrainska Pravda.

The accident happened on the Burgas-Malko Tarnovo road near a checkpoint leading to Türkiye. The report said the bus had been carrying 37 passengers and two drivers, all Ukrainian nationals, and had stopped after running out of fuel. When passengers got off and gathered behind the vehicle, it began rolling backwards, struck a group of people and came to rest in a roadside ditch.

The source also noted that the bus overturned into a ravine, and that the road section included sharp bends and steep terrain. Those details matter because they point to a combination of mechanical failure, terrain and human exposure at the roadside rather than a simple forward collision. The bus driver was detained by regional police in Malko Tarnovo, and an investigation is under way.

Emergency services transported six injured people to hospitals in Burgas and another 10 to an emergency care centre in Malko Tarnovo. The remaining passengers were temporarily housed at a reception centre in the border town, where they received medical assistance and other support.

The report says the trip involved Ukrainian nationals, including some refugees living in Burgas. That detail suggests the group may have included people living in Bulgaria rather than only travellers passing through. It also gives the crash a wider social context, since transport incidents near border crossings can affect both residents and travellers in transit.

The available reporting does not explain whether the fuel shortage itself was part of a wider maintenance failure or simply an isolated operational problem. Nor does it say whether the bus had mechanical braking issues, whether the driver had attempted to prevent rollback or whether the road gradient contributed to the vehicle’s movement.

What is verified is that the accident was deadly, fast-moving and chaotic. A bus full of passengers stopped on a steep road, rolled backwards and struck people standing behind it. Two died, 16 were injured and the driver was detained while authorities began to reconstruct the sequence.

For readers, the incident is a reminder that road accidents can become mass-casualty events even without a high-speed head-on impact. In this case, the combination of fuel exhaustion, steep terrain and a crowded roadside created conditions for a fatal rollback.

The accident also highlights the danger of roadside crowding after a bus stops on a steep route. Once passengers had gathered behind the vehicle, the rollback became deadly. That sequence means the disaster was not just about the bus moving backwards; it was about the loss of safe space around it on a road with little margin for error.

Because the driver has been detained, the investigation may focus on whether the bus was properly secured after running out of fuel and whether the road gradient should have made that stop unsafe in the first place. The source does not provide the answer, but it does make clear that a routine interruption turned into a fatal chain reaction within moments.
