Rescuers blocked from reaching 41 trapped construction workers have shifted to an attempt to dig towards them vertically after the nine-day effort in mountainous northern India was stymied by debris and technical glitches.

The trapped workers are healthy and receiving food like nuts, roasted chickpeas and popcorn though a pipe, government spokesperson Deepa Gaur said.
