Dhruv helicopters fly high in Uttarakhand | The Hindu Prove their mettle dropping paratroopers in some of the most inaccessible areas Four Dhruv helicopters pressed into service by the Army in flood-hit Uttarakhand have proved their mettle in carrying out relief operations and dropping paratroopers in some of the most inaccessible areas. They have been focussing on the Gaurikund-Kedarnath region. Rescue work assumed urgency as the India Meteorological Department on Thursday forecast more rains in the Himalayan State from June 24 to 28. IMD Director-General L.S. Rathore said the next wet spell was likely to see light to moderate rainfall. Launching one of the biggest rescue operations in Uttarakhand, the Army has mobilised nearly 8,100 troops, as it simultaneously reached out to thousands of stranded people in four regions â€” Rishikesh-Uttarkashi-Harsil-Gangotri; Rudraprayag-Kedarnath; Joshimath-Badrinath and Dharchula-Tawaghat in Pithoragarh district.
