In a sharp response to the terrorist attack in the Pahalgam of Jammu & Kashmir, India announced a series of measures against Pakistan on Wednesday, including the suspension of the Indus-Water Convention that controls the waters of the River Indus.

Everything about the Indus Waters treaty

India and Pakistan signed the Indus Waters treaty on September 19, 1960, after nine years of negotiations, where the World Bank was a signer of the Pact.
The Convention describes a mechanism for cooperation and information exchange between the two parties about the use of the waters of a number of cross-border rivers.

According to the Convention, India has the right to generate Hydro -electricity through the run of the river projects on the western rivers, subject to specific criteria for design and operation.
The treaty also gives the right to Pakistan to increase objections about the design of Indian hydroelectric projects on Western rivers.
