KATHMANDU, MAY 25

A climber from Hungary has gone out of contact from the Hillary Step area above 8,000m on Mt Everest since yesterday.

According to the expedition organiser, Suhajda Szilard went missing after he attempted to scale Mt Everest without supplemental oxygen or personal Sherpa support.

"He was alone and his last location of contact was the Hillary Step," Thaneswar Guragai, General Manager at Seven Summit Treks, said. We had his last GPS tracking record at 8,700m and there has been no signal since then, he added.

Szilard always wanted to go for alpine-style climbing as he did the same in Lhotse, K2, and Broadpeak in the previous seasons. "He only asked us for the base camp support this time," Guragai said, adding that efforts are underway to search for the missing climber but bad weather has been playing a foul in the high camps since this morning.
