Two climbers have reportedly died on Mount Everest in the first fatalities of the season.
Mr Waraich had climbed to the top of the peak, but died after collapsing on the South Summit during the descent.
Mr Liu reached the Hillary Step before turning back, but died before returning to the base of the mountain.
Sherpas had been sent to help both men with extra oxygen and supplies, but to no avail.
The men’s bodies will be recovered when weather permits.
