Early on Wednesday, Subhrasree Chakraborty sent her husband Sudipto Bhattacharya a picture of a departure stamp in her passport at 07:57 local time, confirming she had cleared immigration at the Nepal border. Six minutes later, at 08:03, she wrote: "we are waiting to enter China." Then the messages stopped.
Subhrasree, a critical care medical technologist at a city hospital, was travelling with a group of about 30 people on a pilgrimage to Mount Kailash, the Himalayan peak sacred to Hindus as the home of god Shiva. She had dreamed of making the journey for years. According to her husband, she was physically fit and accustomed to emergencies, but that knowledge has not helped him learn what happened after her final message.
"After 08:03am, what happened? We don't know anything," Bhattacharya said.
The pilgrimage to Mount Kailash resumed last year after being disrupted by the pandemic and then by tensions between India and China. Several thousand Indians have been making the trek annually. The flash floods that struck along Nepal's border with Tibet have now left at least 290 Indians missing, with many of them believed to be pilgrims en route to the sacred site.
Authorities on both sides of the border have yet to provide a clear picture of the casualties or the status of rescue operations.
