Three people have been seriously injured jumping off cliffs on the Jurassic Coast.
Dorset Police was called to the scene at about 3:45pm after reports of safety concerns for people jumping into the sea at Durdle Door, near Lulworth.
Three people have sustained serious injuries and are being treated by paramedics after air ambulances were called.
Police are asking people to stay away from the popular tourist spot, with lifeguards helping to clear the area.
Dorset Police Chief Inspector Claire Phillips said: "We have had to close the beach at Durdle Door to allow air ambulances to land. As a result, we are evacuating the beach and the surrounding cliff area.
"I am urging people to leave the area to enable emergency services to treat the injured people."
Images posted on social media by Purbeck Police show the aircraft landing on the sand and crowds leaving the beach as the area was evacuated.
