Hope for survivors in Nepal as tunnel rescue efforts continue

Eight days after the deadly flash floods at the Nepal‑Tibet border, rescuers continued searching for survivors believed to be trapped in tunnels along Nepal's Trishuli River. At least 1,200 people have died and thousands more remain missing following a "glacial collapse" in the Himalayas that sent floodwaters and debris sweeping across roads and villages. BBC South Asia correspondent Azadeh Moshiri visited one of the tunnel sites.
