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, said Guite.

Lt. Gen. 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 hospitalized, said Guite. He put the number of those still unaccounted for at around 50.
