Climber dies day after posting triumphant message announcing he had made it to top of world's seventh-highest peak

A Greek climber died Tuesday on Nepal's rugged Mount Dhaulagiri, expedition organizers said, in the first recorded fatality of this year's busy Himalayan spring climbing season.

Antonios Sykaris's death came a day after a triumphant Instagram message announcing he had made it to the top of the world's seventh-highest peak. Sykaris wrote that he was dedicating his feat to "my little Iris, my granddaughter."

"Iris, I am at the top !!!" he wrote.
