Travellers are being advised to steer clear of the southern tip of Iceland due to heavy gas pollution caused by small glacial flood.
The Icelandic Meteorological Office has warned people to keep their distance from the Mulakvil river, on the western side of Myrdalssandur, southeast of the capital Reykjavik.
The warning was issued following measurements at a local seismic station indicating that hydrogen sulphide levels were high enough to cause concern for public health.
Travellers who experience symptoms such as nasal burns or eye irritation are advised to leave the area.
Gas pollution is common during glacial floods in Iceland.
