"The number of missing persons is around 4,000 as per government figures. Some NGOs estimated the number of missing persons as 11,600. The state (Uttarakhand) government is compiling figures on the basis of FIRs registered by different states. So, the figures can grow," he told reporters.
Asked if the figure of 11,600 was close to reality, he said "this is an estimate made by NGO. I won't go by it but we cannot also ignore it. The state government is following certain procedures. There are three categories --pilgrims, local residents and those who work as labour. I think an assessment of this numbers will have to go into the official figures".
Unmanned Aerial Vehicles (UAVs) have been used to make sure that nobody is left out in rescue, he said.
Replying to a query, Reddy said state governments should have a full-time vice chairman for disaster management.
