Czech climber Milan Sedlacek died after reaching the peak of Lhotse, the world's fourth tallest mountain at 8,516 metres (28,103 feet), the Czech Lhotse 2012 team said on its website Tuesday.

Sedlacek, 50, reached the peak late on Saturday, but "his great desire ... proved fatal for him as he did not return from the peak of the world's fourth highest mountain," the team said.

The five-member team including Sedlacek climbed the west face of the mountain, which rises near Mount Everest on the border between Nepal and Tibet.
