A tourist has died and two more are missing after an ice cave collapsed during a tour group visit to a glacier in Iceland, police have said.

A group of 25 tourists were on an organised tour of the Breioamerkurjokull glacier in the south of the country when a wall of ice collapsed inside the cave.

Emergency services said they are unable to confirm the nationalities of the tourists at this point.

A complex operation involving around 200 people is under way to try to rescue the two tourists who are thought to be trapped under the ice.

Police for the south of Iceland said in a statement: “A group of 25 foreign tourists of several nationalities were exploring the ice cave when the accident happened.

“A large number of rescuers and responders have taken part in the operation.

“The conditions for the search are difficult and it is now dark. It is not considered defensible due to the danger of the scene to continue the search at night. The search has therefore been postponed and will be resumed in the morning.”
