A group of tourists were exploring an ice cave in Iceland when a piece of the ice ceiling fell, killing one person and injuring another.
The group was on a guided tour of the Breidamerkurjokull glacier when the accident happened.
Rescuers have been searching for two missing tourists since the collapse, but the search has been difficult because of the harsh conditions.
The search will continue in the morning, but the glacier is a dangerous place, so it's not clear if they will be found.
