An explosion hit the Brod oil refinery in northern Bosnia and Herzegovina late Tuesday, killing a worker and injuring 9 others.
The blast occurred in the town of Bosanski Brod near the Croatian border.
Police said in a statement that a refinery employee was killed and nine others injured.
Mayor Ilija Jovicic told local media that the body of the worker had been recovered.
None of the wounded are in critical condition and three have already been discharged after treatment, according to a hospital in Doboj city, 50 kilometers (31 miles) from the accident site.
The mayor earlier told local media that the explosion occurred around 9:30 p.m. local time (1930GMT).
Firefighters are still trying to douse the fire.
Local media reported that the explosion was also heard in the border city of Slavonski Brod in Croatia and the flames from the refinery were visible.
People living in the two areas are extremely anxious, with most of them thinking it was an earthquake.
The Brod refinery is majority-owned by Russian state oil company Zarubezhneft.
