Today's rescue operations focused largely on the nearly 5,000 people who are stranded in and around Badrinath. They are safe because they are in relief camps equipped with food and water, but cannot leave the area as landslides have cut off access to major roads leading to Dehradun and Rishikesh, from where they could be sent home.
