Travel agencies that have sent pilgrims to Uttarakhand have been receiving calls from anxious family members and friends. “We are in touch with our tour supervisors and drivers. Today, we called the families and informed them that all of them were safe,” said a Southern Travels official.

With no power supply and cellphones off the grid, families are finding it difficult to access their loved ones, he said, adding that the number of pilgrims from Karnataka stranded there could be in thousands.
