A state of emergency has been declared in Iceland after lava from a volcanic eruption damaged key hot water pipes.

Thousands of people in the Reykjanes Peninsula have been urged to limit their hot water and electricity use as the pipes could take days to fix.

There are concerns that other crucial pipelines close to the Svartsengi power station could be affected if the lava flow does not ease soon.

It is the third such eruption on the peninsula since December.
