Maharashtra Chief Minister Uddhav Thackeray on Sunday expressed grief over the loss of lives in house collapses triggered by landslides following heavy overnight rains in Mumbai and announced an ex-gratia of Rs 5 lakh for the kin of each of the victims.

Twenty five people died in house collapse incidents after heavy showers, which caused severe water-logging and disruption of suburban train services and vehicular traffic in the metropolis on Sunday, officials said.
