Islamabad: Pakistan warned on Thursday that any attempt by India to restrict water flows under the Indus Waters Treaty (IWT) would endanger regional stability and have serious consequences. According to Anadolu Agency, Foreign Ministry spokesman Tahir Andrabi stated that any effort to curtail water vital for the livelihood of millions of Pakistanis would be 'a deeply irresponsible act' that threatens peace in South Asia and beyond. Andrabi emphasized that the responsibility for such a threat to international peace and security would fall squarely on India's shoulders. 'Pakistan's rights and interests in respect of its water resources are non-negotiable. We will vigorously defend those rights through all available diplomatic, legal, political, economic, and other measures consistent with international law in the UN Charter,' Andrabi told reporters in Islamabad. He further warned that any deliberate attempt to block water essential to Pakistan's survival and development "would constitute an extremely grave ac t with far-reaching consequences." The comments from Pakistan came after Indian Water Minister CR Patil suggested in an interview that New Delhi was working to ensure that 'not a single drop of water' would flow into Pakistan in the coming years. Patil expressed confidence in the progress of work aimed at halting the flow of Indus water to Pakistan, declaring that it was certain no water would reach Pakistan in the future. The Indus Waters Treaty governs the use of six rivers that originate in India and flow into Pakistan, providing water to hundreds of millions of people across the Indus basin. In April last year, New Delhi held the IWT in abeyance following an attack in Indian-administered Kashmir's Pahalgam that killed 26, blaming it on Islamabad. Pakistan rejected the claims and stated that any attempt to suspend its water share would be considered an 'act of war,' noting that the treaty could not be unilaterally suspended. The two arch-rivals later engaged in four days of cross-border armed clashes in May, before US President Donald Trump brokered a ceasefire. Last month, the Hague-based Permanent Court of Arbitration reaffirmed key limits on India's ability to control water flows on the Western Rivers. The IWT divided the six rivers of the Indus Basin between the two countries. While India received the three eastern rivers, namely Sutlej, Beas, and Ravi, Pakistan was assigned control over the three western rivers: Indus, Jhelum, and Chenab. Pakistan asserts that India's planned hydropower dams will cut flows on the river, which feeds 80% of its irrigated agriculture.
