MUMBAI - A four-storey residential building collapsed in India's financial capital of Mumbai overnight, killing at least 11 people, with more feared trapped under the rubble, officials said on Tuesday.

Part of the building, located in a crowded suburb in the central part of the city, crumbled to the ground at around midnight on Monday, the city's civic body BMC said.

Rescue workers were working to pull out debris and rubble until late on Tuesday, with work hampered by heavy rain.

Building collapses are common in Mumbai during monsoon season, mostly due to poor construction.
