In the early hours of Tuesday morning, Samuli Mansikka of Helsinki became the fourth Finn to reach the summit of Mount Everest, the world's highest mountain.
Mansikka, 30, follows in the footsteps of Veikka Gustafsson, who first conquered Everest in 1993 and has since climbed it again in 1997 and 2004, and Ari Piela and Antti Mankinen, who reached the summit from the Tibetan side in 1999.
Mansikka used bottled oxygen on the ascent.
"Veikka Gustafsson manages to make climbing without bottled oxygen look easy. In reality, I think it is probably only a small fraction of those who climb Everest who can reach the summit without oxygen", wrote Mansikka on his website a few days ago.
He was leading a six-member team up the mountain. Five of them claimed the summit.
