The beach in the south of England covered with an unknown chemical cloud

 
More than 100 people were hospitalized as a result of poisoning with an unknown chemical substance in the south of England in the county of East Sussex.
On Sunday, holidaymakers on the beach of Birling Gap began complaining of shortness of breath, burning eyes and vomiting.
Eyewitnesses said that the cloud came from the sea, in the air at that time there was a smell of chlorine.
Rescue services conducted evacuation and sent 133 people to hospitals. The county police began an investigation.
In the past similar incidents were caused by leaks from an industrial enterprise in France, but there is no confirmation of this information yet.
The fire and rescue service of East Sussex noted that "chlorine poisoning is extremely low-gravity," because the consequences of poisoning would be much more serious.
People living on the pavement are advised to keep the windows and doors closed and, if possible, not leave the house.

As one eyewitness told Kyle Crickmore, who was on the beach of Birling Gap with his family, soon after people felt unwell, the entire coastal strip was emptied.
According to him, the chemical cloud appeared unexpectedly, after which a strong smell of chlorine appeared in the air.
"It was something very strange, although 10 minutes before that day it was clear and sunny, it was very hot and a lot of people [at the beach]." Everything was empty in 10 minutes, which is incredibly insuperable, given that the people were very much " , - he said.
