"Our clients said the Sherpas manhandled them," he said.
A statement posted Sunday on the website of Italian climber Simone Moro gave a harrowing account, claiming that 100 Sherpas attacked him, Swiss climber Ueli Steck and British climber Jonathan Griffith.
This account said the fight broke out after Sherpas said the climbers knocked ice onto a Sherpa located below them.
"They became instantly aggressive," the statement said, "and not only punched and kicked the climbers, but threw many rocks as well."
