Relentless monsoon rains sweeping through Northeast India have left at least 25 people dead and caused widespread devastation, local authorities confirmed on Sunday.

In Assam’s Guwahati, a deadly landslide triggered by torrential downpours buried multiple houses, resulting in the deaths of five people—three of whom belonged to the same family. Elsewhere in the state, flooding killed three more individuals, with fatalities reported from Golaghat and Lakhimpur districts.

Arunachal Pradesh, which borders China, faced its own tragedy as seven people were killed after their vehicle was washed away by powerful floodwaters. In a separate mishap, two individuals drowned, raising the death toll in the state to nine.

States including Mizoram, Tripura, and Meghalaya also bore the brunt of the heavy rainfall, with eight deaths reported in the last 24 hours due to landslides and sudden floods.

Manipur’s capital, Imphal, has been brought to a halt following three consecutive days of downpour. Waterlogging has impacted several parts of the city, prompting warnings and calls for evacuation for those residing near the Imphal River.

In north Sikkim, landslides cut off major routes, leaving nearly 1,500 tourists stranded. A tragic accident earlier this week saw a vehicle carrying 11 tourists plunge into the Teesta river in Mangan district—killing one, injuring two, and leaving eight missing.

The India Meteorological Department (IMD) has forecast more heavy rain for the region in the coming days. It has issued red and orange alerts for parts of Assam and surrounding northeastern states.

Assam continues to be severely affected, with floods and landslides impacting 17 districts and displacing over 78,000 residents. More than 1,200 people have taken refuge in five designated relief shelters. Lakhimpur district remains the worst hit, accounting for more than half of those affected.

In response, massive relief and evacuation efforts are underway. Teams from the National and State Disaster Response Forces, along with local police and fire departments, have been mobilised to assist those trapped or displaced by the floods.

Meanwhile, educational institutions remained closed in two districts on Saturday, and heavy rainfall disrupted air traffic at Guwahati airport a day earlier.

Arunachal Pradesh officials said rescue operations were ongoing, and damage assessments were being conducted to provide emergency aid to those impacted.
