Family members pin photos of Nepal’s missing to hospital wall as people try not to give up hope on loved ones

• Nepal-Tibet flash flood – latest updates

Posters of missing people line the wall of the hospital, the glue still fresh beneath. A schoolgirl smiling in her uniform; a beaming, chubby-cheeked baby; a couple smiling on their wedding day; a young man, hands on hips, atop a mountain peak; a young girl with flowing hair, peeking out from behind a door.

These faces are just a fraction of the thousands who have not been seen since deadly flash floods coursed through the Himalayas and wiped away entire villages. By Saturday morning, the toll of the missing had risen to almost 3,000, in both Nepal and Tibet.

The impact of the glacier collapse was so strong that experts initially reported it as an earthquake. The Nepali village homes that lined the riverbank and clung to the mountainside stood little chance.
