Aerial footage shows a firefighting helicopter picking up seawater and dropping it over flames as more than 100 firefighters worked into the evening to contain a massive wildfire that broke out at Dunwich Heath in Suffolk, eastern England, on Wednesday.

Dozens of people were evacuated from nearby homes, holiday cottages and a mobile home park as the fire spread.

According to Suffolk's fire service, the wildfire has burned an area larger than 200 football pitches. Officials say the major incident response is expected to continue for at least another 48 hours.
