A slab of ice Thursday was snapped off by one of the climbers starting a summer avalanche on Mount Blanc in the French Alps, reported the Washington Post.
"Unusually we weather" in recent days up to the event may have been part of the problem reported Fox News.
The two mountaineers who have died are from spain, reported Fox.
Rescuers were sent to pull the dead and injured from the mess but risks of another avalanche delayed their efforts, reported Fox.
According to the Washington Post, the climbers involved seemed experienced.
