Two climbers, one from the US and one from Switzerland, have died on Mount Everest.

Organizers of the expedition told Agence France-Presse that the two climbers died Wednesday.

They were the first deaths reported in this year's climbing season, according to AFP.

Chhang Dawa Sherpa from Seven Summit Treks told AFP the Swiss climber died near the mountain's summit after suffering from exhaustion. He said the climber had reached the top of the mountain.

And AFP reported that the American climber reached the site of the Hillary Step but then experienced snow blindness and exhaustion. It reported that he was brought back to Camp 4 but died later.

Snow blindness is an eye condition cause by overexposure to ultraviolet light. Several Everest climbers have experienced this condition in the past.
