Chairman of the Joint Chiefs of Staff Committee, General Rashad Mahmood, and his team briefed the senate members about the threat, Dawn online reported.
The Senate committee, led by Mushahid Hussain, was also informed that India had over the last couple of years purchased weapons worth $100bn 80 per cent of which were Pakistan-specific, reported media.
The report also said that the Indian army would be buying weapons worth another $100 billion over the next five years.
India, which is the world's second largest arms importer, has more than doubled its military spending over the last decade. Delhi's defence budget for this year was $40.07 billion.
This requires a continuous evaluation of the situation and upgradation of the response mechanism, the members were informed.
