Firefighters were battling to control the blaze after a number of buildings containing hazardous materials caught fire overnight Saturday in an industrial and logistics complex in Haifa.
Explosions were heard, apparently as the flames detonated the contents of the building. Video posted to social media showed flames engulfing the structures.
It was unclear what had been stored in the buildings, with some of the explosions appearing to produce light-colored flames.
No casualties were reported in the fire, but three people were rescued from nearby homes.
Firefighters were working to prevent the flames from spreading to nearby structures.
Haifa is a key location for industry, with a number of plants and processing centers linked to the oil and chemical industries.

Residents and activists have long called for steps to be taken to combat the significant air pollution and above-average incidences of cancer and respiratory diseases they suffer.
In addition, there have been concerns for years of a potential disaster if a rocket fired by Hezbollah were to hit a chemical facility. The Lebanon-based terror group has in the past threatened to target chemical processing sites in any future conflict with Israel.
