Three labourers were killed and seven others suffered injuries after a makeshift water tank collapsed at a labour camp in Maharashtra’s Pune district on Thursday morning, police said.

The incident took place in Bhosari area of Pimpri Chinchwad township when some labourers were taking bath under the water tank, they said.

“It seems a wall of the water tank exploded due to the water pressure, leading to the collapse of the tank,” Additional Commissioner of Police, Pimpri Chinchwad Vasant Pardeshi said. The labourers who were below the water tank got trapped under the debris, he said.
