A group of about 25 foreign tourists from several nationalities were exploring the caves of the Breidamerkurjokull glacier in Iceland when the ice collapsed, authorities said.
At least one person has died, and two others are still missing after an ice cave partially collapsed as a group of tourists was visiting the Breidamerkurjokull glacier in southern Iceland.
In a statement posted on social media, local police say first responders received a call shortly before 3 pm local time (5 am CET) on Sunday as a group of about 25 foreign tourists from several nationalities were exploring ice caves when four people were hit by ice.
Two people were seriously injured: one died at the scene, while the other was flown by helicopter to a hospital in the capital and is reported to be in stable condition.
A large number of rescuers worked throughout the afternoon and into the evening, searching for the two missing people. The operation was paused after dark due to the dangerous conditions, but the police said it would resume in the morning.
Icelandic public broadcaster RUV reported that efforts to transport equipment and personnel up to the glacier had proven difficult due to the rugged terrain and cutting through the ice was mostly done by hand with chain saws.
Local news site Visir said the group was on an organised ice cave tour and were accompanied by a guide but most people were outside the cave when it collapsed.
The ice cave is a popular destination for tourists.
The collapse was likely not related to a volcanic eruption in southeast Iceland on Friday, around 300 kilometres away from the glacier.
