A four-year-old boy was killed and six people were injured when a house collapsed in suburban Kandivali on Saturday afternoon, a Brihanmumbai Municipal Corporation (BMC) official said. The incident took place at K D Compound in Lalji Pada area around 4 pm.

Drainage work was going on in the area and it could be the reason for the collapse of the ground-plus-one-storey house, the official said.
