A house in the village of Sokolovo, near Karnobat, caught fire yesterday, the Interior Ministry said. The house belongs to a 57-year-old local man. Part of the building burned, not all of it.

Karnobat police received the alert shortly after 1:30pm.

The fire started in a convector heater fixed to the wall in one of the rooms. The ministry says the most likely cause is a technical fault.

Officials are still assessing the damage. Police have opened pre-trial proceedings over the fire.
