Police forces have been responding to calls from concerned residents after they smelt a foul-smelling gas in the south east.
A Kent Fire and Rescue Service spokesman said: "South Kent residents are being asked to keep doors and windows closed due to a gas cloud that is believed to have come across from France, following reports of a gas leak from a factory 75 miles west of Paris."
Meanwhile, Metropolitan Police tweeted that the gas did not pose a risk to the public:
We are aware of reports of a strong noxious gas like smell in some South East London boroughs - no risks to public
