At least six children were killed when a five-storey building collapsed in Behrampada slums in Bandra East here on Thursday afternoon, officials said.Another five persons, including some adults sustained injuries while eight persons who were trapped under the debris of the building were rescued, BMC Disaster Cell officials said.The building, which came crashing down around 1.30 p.m, was situated near the National School on A.K. Marg, adjacent to Bandra station, in a congested slum locality.BMC officials said that the building was in a dilapidated condition and had been served evacuation notices in the past which the residents ignored.Rescue and relief operations were reported to be hampered owing to road-widening work going on in the area, locals said.The six victims were identified as Ayesha Ahmed Khan, 12, Alinisar Ahmed Khan, 3, Osama Nissar Khan, 14, Afisa Nissar Khan, 1 year old, Arivi Nisar Khan 2, and Rasudhi Nissar Khan, 16.
