Mount Everest Tragedy: 4 Dead, 2 Missing After Ice Collapse

Video footage captured by climbing guide Vinayak Malla shows the crowded summit ridge of Mount Everest before and after a cornice collapse that resulted in two climbers going missing. Four climbers managed to self-rescue thanks to fixed ropes, but there is little hope of finding the missing climbers. The incident adds to the season's fatalities, including the recent discovery of Kenyan climber Joshua Cheruiyot Kirue's body. Malla's efforts to break a new route likely saved many lives.
