ISLAMABAD: Pakistan said on Thursday it had observed abrupt variations in the flow of the River Chenab during the ongoing month, accusing India of manipulating river flows at a critical point in the agricultural cycle and saying it had written to New Delhi seeking clarification.

Local media reported quoted Pakistani officials as saying India released about 58,000 cusecs of water at Head Marala on Dec. 7–8 before sharply reducing flows to roughly 870–1,000 cusecs through Dec. 17, far below the 10-year historical average of 4,000–10,000 cusecs for this period.

Pakistan’s Foreign Office spokesman Tahir Andrabi told a weekly media briefing in Islamabad India had failed to share prior information or operational data on the Chenab flows, a practice he said New Delhi had previously followed under the 1960 Indus Waters Treaty. New Delhi said earlier this year it had put the treaty “in abeyance” following a gun attack in Indian-administered Kashmir that it blamed on Pakistan, a charge Islamabad denied, calling instead for an impartial and transparent international investigation.

Pakistan also described India’s unilateral suspension of the treaty as a violation of international law and an “act of war.”

“Pakistan would like to reiterate that the Indus Waters Treaty is a binding international agreement, which has been an instrument of peace and security and stability in the region,” Andrabi said. “Its breach or violation, on one hand, threatens the inviolability of international treaties in compliance with international law, and on the other hand, it poses serious threats to regional peace, principles of good neighborliness, and norms governing interstate relations.”

Andrabi said Pakistan viewed the sudden variations in the Chenab’s flow with “extreme concern and seriousness,” saying the country’s Indus Waters Commissioner had written to his Indian counterpart seeking clarification in line with procedures outlined in the treaty.

“Any manipulation of river flow by India, especially at a critical time of our agricultural cycle, directly threatens the lives and livelihoods, as well as food and economic security of our citizens,” he continued. “We call upon India to respond to the queries raised by Pakistan.”

He said Pakistan had fulfilled its obligations under the Indus Waters Treaty and urged the international community to take note of India’s “continued disregard” of a bilateral treaty and to counsel New Delhi to act responsibly under international law.

Andrabi maintained Pakistan remained committed to peaceful resolution of disputes with India but would not compromise on its water rights.

In the same briefing, he also condemned an incident in which the chief minister of the Indian state of Bihar was seen in a video forcibly removing the hijab of a Muslim woman during a public interaction, followed by remarks by a minister in Uttar Pradesh who mocked the episode, saying it reflected a broader pattern of religious intolerance and Islamophobia and warranted strong condemnation.
