Three days after a devastating earthquake measuring a forceful 6.8 on the Richter scale struck large parts of north and east India, rescue and relief teams are still trying to reach thousands of people trapped in remote areas. Many villages in quake-hit Sikkim are still out of reach and thousands are said to be waiting for help. Rescue operations remain the biggest challenge as rain and landslides are severely hampering the efforts and bad weather is not allowing helicopters to land.
