Floods and landslides kill over 30 in Assam, Arunachal Pradesh, Mizoram, Tripura, Nagaland, Sikkim, and Meghalaya

Arunachal Pradesh recorded the highest number of casualties, with nine deaths, followed by six in Meghalaya and five each in Mizoram and Assam. One fatality was reported in both Tripura, Sikkim and Nagaland. Authorities have yet to release details regarding the remaining two deaths.

The death toll is preliminary and expected to rise as the situation continues to unfold. Some reports already indicate higher tolls of up to 35.

In Arunachal Pradesh, a massive landslide triggered by incessant rains killed seven people — including two women and two children — on National Highway 13 in the East Kameng district on Saturday, May 31.

More than 60 000 people have been affected, and over 10 000 are already displaced.

Assam has also been severely affected. Continuous rainfall has led to deadly landslides in the Kamrup Metropolitan district, claiming five lives between Saturday and Sunda.

Three women were killed in the Bonda area near Guwahati, confirmed Urban Affairs Minister Jayanta Malla Baruah. The Assam State Disaster Management Authority (ASDMA) has been coordinating relief and rescue efforts in the region.

One person was killed, two injured, and eight others went missing when a vehicle in which 11 tourists were travelling plunged into the Teesta river in Mangan district, Sikkim, on Thursday night, May 29. The vehicle plunged more than 305 m (1 000 feet) into the river near Munsithang along the Lachen-Lachung highway.

Nearly 1 500 tourists were stranded in various parts of north Sikkim on Saturday as the main road was blocked due to landslides triggered by incessant rains, officials said. Mangan’s SP Sonam Detchu Bhutia said 115 tourists are stranded in Lachen and 1 350 tourists in Lachung.

Multiple roads have been damaged or destroyed, including National Highway 17, isolating villages in the region and hampering rescue efforts.

Authorities are on high alert as rescue and relief operations continue across 12 affected districts in Assam.

The region is experiencing record-breaking rainfall — Guwahati recorded 111 mm (4.37 inches) of rain, the highest in a single day in 67 years, causing rivers like the Brahmaputra to swell.

The India Meteorological Department (IMD) has issued red and orange alerts for parts of Assam, and orange and yellow alerts for other northeastern states, including Meghalaya, Manipur, and Mizoram.
