Olena Kalynychenko is among thousands missing after devastating floods hit the Nepal-China border. She was on a spiritual retreat to Mount Kailash with 55 others, mostly from Ukraine. The floods, caused by a collapsed Himalayan mountain slope, have killed over 1,400 people in Nepal and China, with more than 6,000 missing. The group was crossing from China into Nepal on the day the floods hit, with one person confirmed to have crossed shortly before the floods started. Families are desperate for news, but many are still waiting for any information about their loved ones.
