Arunachal Pradesh: Flash floods and landslides as monsoon rain triggers multi-agency rescue

📌 Summary:

• Monsoon rain triggered flash floods and landslides across Arunachal Pradesh; in Lower Dibang Valley, seven locals who set out to rescue four fishermen stranded in the swollen Sisiri river were themselves stranded when their raft overturned
• A multi-agency rescue (NDRF and an IAF helicopter, with locals even attempting to use elephants) eventually saved those trapped; at least three people have died over the past week and roads and highways have sustained significant damage
• A cloudburst blocked the Hoj–Potin road in Papum Pare district, cutting connectivity to neighbouring districts; a red alert was in force in Arunachal, while floods in Assam affected around 16,000 people and hit railway services
