Heavy black smoke rose over an industrial plant near Neot Hovav in southern Israel on Sunday after debris from an intercepted Iranian missile struck the site.
A pesticide tank caught fire, sending thick plumes into the sky. Officials said there were no injuries and no wider risk, though nearby areas were evacuated as crews worked to contain the blaze.
A day later, a fire broke out at an oil refinery in Haifa, the second such incident this month.
Footage showed flames and dark smoke from a storage tank before firefighters brought it under control. The cause was not confirmed.
The incidents come as Israel and Iran exchange strikes, with regional air defences activated across the Gulf.
