A fire at a chemical factory in the northern French city of Rouen threatens to pollute the River Seine, local officials have warned.
Schools in the area were closed and residents advised to remain inside as 200 firefighters, with 60 fire vehicles, tried to put out the blaze.
Thick clouds of black smoke billowed from the fire, though officials said tests showed the smoke was not toxic.
No-one was injured, and the cause of the blaze was not immediately clear.
The fire broke out at a storage facility owned by Lubrizol, a US specialty chemical manufacturer owned by the billionaire investor Warren Buffett.
