GAUHATI, India (AP) — Rescuers found more bodies Friday as they resumed searching for dozens of missing after a mudslide triggered by weeks of heavy downpours killed at least 19 people at a railroad construction site in India’s northeast, officials said.

Soldiers joined more than 200 workers and police using bulldozers and other equipment to rescue those buried under the debris in Noney, a town near Imphal, the capital of Manipur state. But the terrain is making it difficult to move heavy equipment, said H Guite, district magistrate, adding that he has asked for reinforcements.

Intermittent rain continued in the region where 19 bodies have been recovered so far after a hillock caved in and buried the railroad project area, Guite told The Associated Press.

Lieutenant General R.P. Kalita, head of the army’s eastern command, visited the site. He said 13 soldiers and five civilians have been rescued from the debris of the entirely swept away railroad station, staff residential quarters and other infrastructure that was being built.

The army also set up a medical post at the site to treat those rescued, Kalita said.

Eighteen people with injuries have been hospitalised, said Guite. He put the number of those still unaccounted for at around 50.

A flowing river has been blocked by the debris, creating a dam-like structure, he said. People living nearby have been asked to move to safe areas.

Ten of the confirmed dead were members of the Territorial Army. Because of a decades-old insurgency seeking a separate homeland for ethnic and tribal groups in the area, army personnel had been providing security for the railway officials.

Most of those carried off in the mudslide were sleeping when it hit the area early Thursday. Some survivors recalled being swept down by the gush of the hill debris, The Times of India daily cited Daichuipao, a resident, as saying.

Prime Minister Narendra Modi said he reviewed the situation with local authorities. “Assured all possible support from the Centre (federal government),” he tweeted.

Continuous rainfall over the past three weeks has wreaked havoc across India’s northeast — which has eight states and 45 million people — and in neighbouring Bangladesh.

An estimated 200 people have been killed in heavy downpours and mudslides in states including Assam, Manipur, Tripura and Sikkim, while 42 people have died in Bangladesh since May 17. Hundreds of thousands of people have been displaced.
