Three labourers trapped under the debris after the collapse of a crumbling well that was being repaired in Madhya Pradesh's Chhindwara district on Tuesday, died on Wednesday.
Six of the labourers were pulled out alive from the debris on Tuesday, while three of them remained trapped inside the well.
A joint rescue operation was carried out by the SDRF and NDRF for 20 hours, however, by the time the rescue team reached the three workers on Wednesday, they were already dead.
Officials said that the rescue operation was slowed down by the flow of water into the well, and they had to dig a parallel hole to reach the labourers trapped at a depth of 30 feet.
The deceased labourers have been identified as Wasid Khan (18), Sehzadi Khan (50) and her son Rashid Khan (18).
