http://www.bbc.com/news/world-asia-41105553Rescuers are searching for at least 30 people feared trapped in a building collapse in Mumbai.Local reports say a five-storey building in India's financial capital toppled early on Thursday.The building in the densely populated Bhendi Bazaar area was believed to be more than 100 years old.Ambulances, fire engines and members of the disaster relief force are working at the site. Mumbai is recovering from heavy rains and flooding.The residential building gave way around 08:40 India time [03:10 GMT], reports said."Forty people are believed to be stuck inside and a 43-member team is conducting rescue operations," an official for India's National Disaster Response Force (NDRF) told AFP. Building accidents are not uncommon in India, particularly during the monsoon season. Poor construction standards and old dilapidated structures are often to blame.Every year, dozens of people are killed in building collapses across India.In July, 17 people were killed when a four-storey building collapsed in the Mumbai suburb of Ghatkopar.
