An environmental campaigner, nicknamed the "human polar bear", has swum 1km (0.62 miles) across a glacial lake on Mount Everest to highlight the impact of global warming.
Lewis Gordon Pugh, 40, from Devon, wore only swimming trunks, goggles and a swimming hat to face the 2C waters of Pumori Lake at 17,000ft (5,300m).
He said he hoped to bring the "world's attention" to the melting of glaciers and its effect on the region.
