Pakistan has warned India of reprisal if New Delhi breaches the World Bank-sponsored Indus Waters Treaty, the media reported on Tuesday.
"India will be responded (to) if it shows aggression by unilaterally breaking the treaty," the Express News quoted Water and Power Secretary Younis Dagha as saying on Monday.
Dagha was addressing the Senate Standing Committee on Water and Power.
The Committee met to reconsider a report regarding an adjournment motion moved in the upper house of Parliament by Senator Sherry Rehman.
Rehman moved the motion in the backdrop of reported Indian threats to unilaterally revoke the treat.
The Pakistan People's Party senator had sought details about the possible repercussions of the move and Pakistan's preparedness to combat such "a war-like situation".
"If India shows aggression, then there are some other options," he added. "India cannot stop more water from Neelum river. It can stop water only for temporarily using it."
Dagha said the government had started work on a National Water Policy 2016 and consultations would be completed in the next one to two months.
