More than 22,000 people have been affected as relentless rainfall triggered flash floods, landslides, infrastructure damage
June 29, 2026: Flash floods triggered by heavy rainfall have caused widespread destruction across Assam and Arunachal Pradesh, damaging homes, roads, and public infrastructure. In Assam’s Dhemaji district, a major portion of a railway bridge built in 1965 collapsed, forcing the indefinite suspension of train services between Archipathar and Simen Chapari stations. On Monday, Union Home Minister Amit Shah spoke with Assam Chief Minister Himanta Biswa Sarma to review the flood situation and ongoing relief efforts.
According to the Assam State Disaster Management Authority (ASDMA), over 22,000 people have been affected across six districts, with Dhemaji emerging as the worst-hit. Floodwaters have submerged 96 villages, damaged nearly 1,690 hectares of farmland, and affected more than 48,000 animals. The Northeast Frontier Railway (NFR) stated that the bridge collapse occurred after heavy rainfall eroded the riverbank, destabilising one of its supporting piers. No casualties or damage to trains were reported.
In neighbouring Arunachal Pradesh, continuous heavy rain and a recent cloudburst have triggered flash floods and landslides, leaving at least three people dead while search and rescue operations continue. Authorities have issued warnings for more thunderstorms and heavy rainfall, cautioning residents about the risk of further floods and landslides. The overflowing Leku River has inundated several villages, including Kedichuk in Assam’s Jonai subdivision, while displaced families have moved to temporary relief camps after losing homes and belongings.
