Sensation prevailed in Sonitpur district and its nearby areas on Friday around 12 noon following a massive sound akin to that of a blast forcing residents to rush out of their homes.
However, later it was known that an air force training exercise was held and it triggered a sonic bomb from Sukhoi-30 MKI that shattered window panes of the houses down below.
When asked about the matter, Defence spokesperson in Tezpur, Lt Col Harsh Wardhan Pande said the exercise was a routine of the Air Force training which is conducted during their training period.
The deafening sound was heard across Dhekiajuli to Gohpur in between two districts of Sonitpur and Biswanath in central Assam.
The sound was so loud that could be heard at other places also. Sources said few days before a same sound was heard in Mangaldoi district also.
