A brave photographer managed to get within metres of an active volcano despite it spewing out lava waves over 140 metres high. Silhouetted against a fiery fountain of red, Icelandic photographer, Tómas Freyr Kristjánsson, 37, braved blistering temperatures to get as close the volcano as possible. Although very few were brave enough to get so close, Tómas managed to photograph nearby tourists to give some scale to the spraying molten rock, including that of a nearby motorcyclist.

The claws are out for North Korean dictator Kim Jong-un and Russia's Vladimir Putin – as cats now able to use a model of him as a scratching post. And moggies can also maul at Russian president Vladimir Putin, whose face also features on the new cat toys which are 1.5ft tall and cost £4,500. They are made from hessian rope, and 3D-printed faces are then attached to the posts, before they are handpainted. The toys took a team of artists 200 hours to finish. (Photo by The Pussycat Riot)
