It also damaged pedestrian bridges, water pipelines and electricity supply lines, an official said.

The cloudburst occurred over the Shanta river, causing inundation of areas along its banks with a huge amount of slush-containing boulders, SHO of the Devprayag police station Mahipal Singh Rawat said.

Two municipality buildings, including the multi-purpose Nagar Palika Bhawan, caved in after being hit by the rubble brought down by the cloudburst, he added.
