Panic gripped the area when splinters of two bombs fell in Baldev Nagar, located adjacent to an IAF station.
The IAF authorities could not be contacted, but Ambala Police Commissioner Rajbir Deswal, who reached the spot, said that they would take up the matter with the IAF.
The echo of the explosion was so high that the people came out from their houses out of panic. The pieces of iron type metal fell on the roof of dozen of houses.
The windowpanes of around one dozen houses were also damaged. A part of the wall of a house was also damaged following the high-intensity explosion, they said.
Besides Deswal, Deputy Commissioner K M Pandurang and Deputy Commissioner of Police (DCP) Vinod Kaushik also visited the affected areas.
The Air Force authorities did not inform the district administration before defusing the bomb close to the locality, they said.
