Late on 18 December, a volcano erupted in southwest Iceland, spewing lava and smoke more than 100 metres into the air after weeks of intense seismic activity.
Thousands of people have been evacuated and gas pollution could still occur in the area of the capital Reykjavik late on Tuesday evening or Wednesday morning.
Here are some of the images captured during and after the eruption.

Live footage of the eruption showed bright yellow, orange and red lava in sharp contrast against the sky.
Some tourists were in awe at the spectacle.

"It's a once in a lifetime for us so we don't want to miss that... It's a bit far from here but you can still see some lava coming up, for us this is amazing."

But at its southernmost point the crack was still 3km away from Grindavik, Iceland's Meteorological Office said, and the power of the volcano was decreasing.
"The eruption is taking place north of the watershed so lava does not flow towards Grindavik," geologist Bjorn Oddson told public broadcaster RUV.

The eruption is about 30km from Reykjavik.
The Blue Lagoon, a geothermal spa popular with tourists, has been largely closed since the seismic activity was detected.
"It could potentially go on for several months, it could also just stop later today or tomorrow," said Halldor Geirson, an associate professor at Institute of Earth Sciences at the University of Iceland.

Geirson said most of the lava was flowing into an area where there was little infrastructure.
