Civic-authority workers clear the road, blocked by uprooted trees following strong winds and heavy rainfall in Mumbai on July 5.

Six people, including five children, were killed when a building collapsed in Mumbai, officials said Monday, as monsoon rains pounded India's financial capital, flooding roads and leading to school closures.

A dilapidated residential building collapsed Sunday in the megacity's east, trapping residents under the debris, Mumbai Mayor Ritu Tawde said in a statement.

The deaths came as heavy rainfall paralysed parts of the city, with the India Meteorological Department recording more than 200 millimetres (7.8 inches) of rain within 24 hours.

Hundreds of millions of people in India rely on the annual monsoon winds to bring vital rains that sustain agriculture and industry.
