The compound wall of a building, located in Kurar village, collapsed on hutments on a hill slope in the wee hours.

The chief minister told reporters that the administration, police and National Disaster Response Force (NDRF) teams are keeping a close watch on the situation.
“Last night, unprecedented rainfall was witnessed in Mumbai which led to several mishaps. In Malad, slums were destroyed after a wall collapsed and 30-40 people were injured. I personally met them today at the hospital,” he said.
Fadnavis said forces are on alert as high tide is expected.
