Five Indian Army personnel are missing after a flash flood swept away shelters at a camp in Dibang Valley, Arunachal Pradesh, while four road construction workers were killed in a landslide in Upper Subansiri district — both incidents occurring late on Friday, 15 August following heavy rainfall, officials confirmed.
What Happened in Dibang Valley
A flash flood struck the Pasu Pani Army Camp, sweeping away two shelters belonging to the 5th Grenadier regiment. According to officials, seven personnel were washed away; two have since been rescued, while five remain missing. The State Emergency Operations Centre confirmed the incident took place on Friday evening.
Two search and rescue teams from the 5th Grenadier have been deployed at the site. Personnel from the 58th Battalion of the Indo-Tibetan Border Police (ITBP), the 62 RCC of the General Reserve Engineer Force, Arunachal Pradesh Police, and local volunteers have also joined the operation. A State Disaster Response Force (SDRF) team from Pasighat is being dispatched to Anini to bolster the search effort.
Landslide Kills Four at Road Construction Site
In Upper Subansiri district, a major landslide struck the Keojaring-Byaching road construction site, burying several workers under debris. Four workers were killed: Tadu Baki, Taji Rai, Markosh Basumatari, and Babul Ali. The body of Babul Ali has been recovered so far, according to the district disaster management officer.
Personnel from Nacho Police Station have been deployed for search and recovery, while Fire and Emergency Services teams from Daporijo and the SDRF are being mobilised. The SDRF team is set to move from Ziro to Daporijo before proceeding to Nacho, where it will operate under the officer-in-charge with assistance from a local guide.
Multi-Agency Response Underway
All concerned agencies are being coordinated for the search and rescue operations across both districts. The twin disasters come amid sustained heavy rainfall across parts of Arunachal Pradesh, triggering flash floods and landslides that have compounded challenges for rescue teams operating in remote, difficult terrain.
Broader Context
Arunachal Pradesh is among India's most flood- and landslide-prone states during the monsoon season, with its mountainous terrain and high river volumes regularly disrupting infrastructure and endangering communities. The incidents in Dibang Valley and Upper Subansiri underscore the acute vulnerability of both defence installations and construction sites in the region during peak rainfall months. Rescue operations remain active, and the situation is being closely monitored by state authorities.
Point of View
With response times stretched by terrain and connectivity gaps. The deployment of SDRF teams from Pasighat and Ziro — hours away from the incident sites — highlights how thin the first-response infrastructure is in the state's interior districts. Until pre-positioned rapid response capacity reaches these zones, the monsoon will keep extracting the same toll.
