“It’s a bit chaotic,” she said. “There are huge plumes of very dark grey smoke billowing.”
“All I know is it was evacuated and there’s no one inside, no one’s been hurt. That’s the only thing we care about at the moment.”
Some road closures were in place, a spokesperson for the fire service said.
One nearby resident posted on social media and said they had heard “loads of explosions” from the blaze as well as the noise of the fire engines.
Another user on X wrote that he had heard a “series of explosions” before the fire.
