The Badrinath National Highway (NH-7) is blocked due to falling of boulders and debris from hill after incessant rain triggered landslides in Uttarakhand's Chamoli district, officials said on Thursday. The same highway was blocked at other places like Pagal Nala and Gulabkoti. As precautionary measures, Chamoli district administration stopped pilgrims at safer places like Gauchar and Karnprayag.
