 A large fire at a plastic steeple, in the eastern Croatian town of Osijek early on October 4, has spread to a nearby building where chemicals were stored, releasing toxic fumes that could pose ecological risks as strong winds began to carry them south, officials said. Residents near the outskirts of Osijek where the fire began were urged to remain indoors and keep windows shut as clouds of thick, black smoke enshrouded the area. Schools were closed and there were unconfirmed reports the smoke was moving towards Bosnia and the South.3 firefighters were injured while trying to extinguish the fire, which began after midnight at Drava's depot in Osijek, local media reported.
