Prakash Kabra recites his elder brother’s mobile number and I carefully tap it into my phone – already knowing the response, but still with a naïve sense of hope.
"The number you are calling is either switched off or unreachable at the moment. Please try again later," says the automated reply.
It’s a response Prakash has heard countless times over the last six weeks. Yet he continues to call, hoping against hope that his brother – missing since deadly floods and landslides devastated India’s Himalayas – will answer.
Along with 14 other family members, Prakash's brother, a businessman from the city of Lucknow, had travelled to the scenic northern region of Uttarakhand for the "Char Dham Yatra" – the most sacred of pilgrimages for the world's one billion Hindus.
But the Kabra family did not return home and their faces, along with thousands of others, now stare out from posters plastered on the walls of police stations, hospitals and bus stations in towns and villages across the area.
