It is also close to the field firing ranges. Some of the ammunition used in exercise Poorna Vijay could also have been stored there. But only the CoI can ascertain it, he added.
Officials say only the CoI can point to the cause of the fire.
The report has been submitted and is being studied. In case the government wants, certain sections of the report could be made public, an officer from the Ordnance directorate said.
