New Delhi ( CNN ) -- At least 13 people were killed and 26 more were injured when a five-story residential building collapsed in the Indian financial hub of Mumbai early Friday , a hospital spokesman said . Dozens of people are feared to be trapped in the wreckage of the region 's latest building disaster . `` It 's a pancake collapse , '' said Sachidanand Gawde , deputy commandant at the National Disaster Response Force ( NDRF ) . `` The exact number of those trapped under the debris is not known , '' he said . Forty-four people had been pulled from the debris as of Friday , including the deceased , Gawde said . One of the survivors is an 11-year-old girl who was heard shouting from inside the rubble that she was alive . `` There is a lot of chaos here , but my boys are closely monitoring any noises or movement from under the debris that can lead us to people trapped inside , '' Gawde said . `` We are using latest rescue techniques so that maximum number of lives could be saved . '' Around 40 people are feared to be buried in the rubble , CNN 's sister network IBN reported , citing the disaster officials . The building , an old construction in southern Mumbai , gave way around 6 a.m. Friday . Fire engines and ambulances rushed to the scene to carry out rescue efforts , Gawde said . The first floor of the building was rented out to a decorating firm , but about 22 apartments were occupied on the upper four floors , said Sitaram Kunte , the commissioner of Brihanmumbai Municipal Council , which owns the building . A spokesman for the council said a notice was issued in April regarding major structural issues with the building . It underwent renovations at that time , and further repairs were scheduled , spokesman Vijay Khabale Patil said . The residents were made aware of the situation , but continued to live in the building , he said . Several buildings in the Mumbai area have crumbled this year , one of them with disastrous consequences . In April , scores of people were killed in the collapse of an illegal multistory building in Thane , a city in the Mumbai region . Deadly collapses have occurred in the city in past years , as well . Housing rights groups say many old buildings in the city are rundown and neglected , while newer ones are often built using substandard materials and have structural problems . People live in them because they do n't have a choice -- in Mumbai , demand for housing far exceeds supply . About 65 % of the population is estimated to live in slums , the groups say . CNN 's Lonzo Cook in New Delhi contributed to this report .
The death toll rises to 13 , a hospital official says . Dozens of people are said to be trapped in the rubble . The old residential building in southern Mumbai gave way early Friday . Around 22 apartments were destroyed on the building 's upper floors , the owner says .
