A fire started because of an accident at the refinery of Hungarian oil and gas company MOL's Croatian unit INA has been extinguished, MOL communications director for Hungary Andrea Pánczél told MTI on Monday.
Four people suffered light injuries in the fire, Pánczél said.
György Mosonyi, who heads MOL's supervisory board and is deputy-chairman of INA's, praised the "extraordinary and brave" work of firemen and INA employees and said MOL would make every effort to support the work of INA and the authorities in an examination to find the causes of the accident.
Croatian state television showed images on Monday morning of a plume of smoke rising about 200 million over INA's refinery in Sisak.
INA confirmed earlier reports that no one was killed in the accident and the fire did not threaten the environment.
MOL holds a 47.46% take in INA.
