Police in the city of Hamburg in Germany warned locals of possible toxins in the air after a fire broke out early this morning at multiple storage facilities.
About 140 people were evacuated after the fire broke out at around 4am local time.
A police spokesperson said it is not yet possible to say how dangerous the situation is.
A spokesperson with the fire department said they had reduced the threat level somewhat, even though the fire was still burning at midday, but that people should remain indoors with windows closed.
Authorities said the fire was in Rothenburgsort, just a few kilometres southeast of central Hamburg, and that the smoke cloud was moving in the direction of the city centre.
Multiple police, fire and other emergency workers were at the scene as a thick cloud of dark smoke billowed upwards.
The police spokesperson said the sky had darkened as a result, but the weather made it difficult to determine how much was smoke and how much was clouds.
