Relentless monsoon rains have wreaked havoc across India’s northeastern states, leaving at least 25 people dead and thousands displaced following days of widespread landslides and flash floods, officials confirmed on Sunday.

In Assam, one of the worst-affected states, five people including three members of the same family were killed in a mudslide that buried multiple homes in the state capital, Guwahati.

Torrential downpours weakened the city’s slopes, prompting fresh landslide alerts from local authorities. Elsewhere in the state, flash floods claimed three more lives, with two fatalities reported in Golaghat and one in Lakhimpur.

Neighbouring Arunachal Pradesh recorded nine deaths, including seven who perished when a vehicle was swept away by raging floodwaters. In a separate drowning incident, two others lost their lives. The state, which borders China, remains on high alert as rescue operations continue.

Mizoram, Tripura, and Meghalaya reported a combined total of eight fatalities over the past 24 hours. Officials said the deaths resulted from a mix of landslides and flash flooding triggered by the unrelenting rain.

In Manipur, three consecutive days of heavy rainfall have paralysed normal life in the state capital, Imphal. Severe waterlogging has been reported across several parts of the city, prompting authorities to issue flood alerts and urge evacuations for those living along the Imphal River floodplains.

Meanwhile, in Sikkim, nearly 1,500 tourists remain stranded in parts of North Sikkim as landslides have cut off major routes. In Mangan district, one person died, two others were injured, and eight are missing after a tourist vehicle plunged into the Teesta River earlier this week.

The India Meteorological Department (IMD) has warned of further heavy rainfall across the northeastern region. Red and orange alerts have been issued for parts of Assam, while other northeastern states are under orange and yellow alerts.

According to the Press Trust of India (PTI), 17 districts in Assam have been affected by floods and landslides, displacing over 78,000 people. Lakhimpur is the worst-hit district, with more than 41,600 residents impacted. Over 1,200 people have taken shelter in five relief camps across the state.

Relief and rescue operations are ongoing in Assam, with teams from the National Disaster Response Force (NDRF), State Disaster Response Force (SDRF), local police, and fire services working to evacuate residents and provide aid.

In Arunachal Pradesh, emergency response teams are also conducting damage assessments and distributing immediate relief to affected communities.

Authorities in Assam said educational institutions in two districts remained closed on Saturday due to safety concerns, while flight operations at Guwahati airport were disrupted on Friday amid heavy rainfall and strong winds.

As the region braces for more rain, state governments have urged residents to stay vigilant and follow official advisories.
