Canadian businessman and German doctor die on Everest, three reported missing.

A Canadian businessman and German doctor died while descending from the summit of Mount Everest and three more climbers were still missing, The Himalayan Times reported Sunday.

Tilak Ram Pandey, the liaison officer for Nepal's Department of Mountaineering at the Ministry of Tourism and Civil Aviation, said Nepali-born Canadian Shriya Shah and 61-year-old Dr. Eberhard Schaaf had both succumbed to the world's highest mountain.
Asian Trekking in Katmandu released a statement saying the Himalayan Rescue Association believed Schaaf died from high-altitude cerebral edema.
Meanwhile, Pandey said 44-year-old South Korean Song Won-Bin, a Chinese climber and a Nepali Sherpa guide had been missing since Saturday.
"Fellow climbers are searching for them," Pandey said.
Song, 44, went missing on Saturday while returning to base camp with several other climbers after scaling the mountain, a Seoul foreign ministry spokeswoman told AFP.
She said a search would begin soon, but did not elaborate further.
Yonhap news agency said Song had collapsed due to altitude sickness and fallen off a cliff. It quoted a diplomat in the South Korean embassy in Katmandu.

More than 3,000 people have climbed the 29,035-foot (8,850m) Everest, which straddles Nepal and China, since it was first conquered by Edmund Hillary and Tenzing Norgay in 1953.

Every year hundreds more set out in April to attempt the climb when conditions are at their best.
