Pakistan has formally written to the United Nations Security Council over the Indus Waters Treaty, the 1960 deal that splits the Indus river system between Pakistan and India. The foreign minister's letter accuses India of trying to divert the western rivers that Pakistan depends on, and asks the Council to take notice.
- Deputy Prime Minister and Foreign Minister Ishaq Dar sent the letter. Pakistan's ambassador to the UN, Asim Iftikhar Ahmad, handed it to the Security Council president on 19 June 2026.
- The letter names two specific Indian projects on the Chenab river: a planned "Link-3" canal in Himachal Pradesh, with work said to begin 1 August, and a "silt flushing" of the Salal Dam in Indian-administered Kashmir.
- The two named projects are part of a wider objection. On 18 June Dar said at least 17 Indian projects on Indus system waterways would hand New Delhi the "tools for hydro-hegemony," which is the scale Pakistan says is at stake beyond any single canal or dam.
- Pakistan's core charge is that India is "weaponising water", trying to illegally change how much of the western rivers reaches Pakistan. Almost all of Pakistan's farming depends on this water.
- The letter also points back to an earlier ruling. The Permanent Court of Arbitration, an international tribunal, had already ruled against India's attempt to suspend the treaty.
- Context: India put the treaty "in abeyance" in April 2025, after a terror attack in Pahalgam, in Indian-administered Kashmir, that killed 26 people. India blamed Pakistan-based militants and said it would hold the treaty in abeyance until Pakistan stops supporting "cross-border terrorism". Pakistan denies the link.
- The dispute hardened in July. On 1 July Pakistan declared formally that the treaty "cannot be amended, revoked, suspended or held in abeyance unilaterally," in remarks by law minister Azam Nazeer Tarar. Foreign Minister Ishaq Dar said meaningful engagement with India "requires reciprocity" and warned that undermining the treaty would threaten the water security of millions.
- Pakistan escalated the language from a legal complaint to an accusation of "weaponisation of water", warning it could have consequences for regional peace and security. It also said it "would take all necessary measures" to secure its share.
- India has not moved. As of 3 July it repeated that the treaty "remains in abeyance over Pakistan-sponsored terrorism," leaving the two positions locked rather than converging.
- A widely shared claim that India had offered to restore the treaty in exchange for Pakistan reopening its airspace was checked and found false by Soch Fact Check on 1 July. No such offer was made.
