The Indus Waters Treaty becomes the latest flashpoint in the India-Pakistan standoff, with both nations retaliating against each other. Pakistan warns that any attempt by India to block its share of water under the treaty would be treated as an 'act of war.' In response, India suspends the treaty, closes the Wagah border crossing, reduces diplomatic staff, and implements trade restrictions. Pakistan declares a full suspension of trade with India, shuts its own Wagah crossing, and closes airspace to Indian carriers. The escalating crisis centers around the Indus Waters Treaty, signed in 1960 and brokered by the World Bank.
