At least 20 people have died after they got buried under the rubble of their home due to landslides in Mumbai's Chembur and Vikhroli areas following heavy rains that lashed the city and its suburbs for several hours late yesterday night and early this morning. Fifteen people have been rescued so far from Chembur's Bharat Nagar area, officials said, adding that those injured have been moved to nearby hospitals for medical attention. Rescue operation is still on in both these areas as more people are feared to be trapped, the official said.
