India has fast-tracked hydropower projects worth $15 billion in Kashmir in recent months, three federal and state officials said, ignoring warnings from Islamabad that power stations on rivers flowing into Pakistan will disrupt water supplies.

The swift approval of projects that had languished for years came after Prime Minister Narendra Modi suggested last year that sharing the waterways could be conditional on Pakistan clamping down on anti-India militants that New Delhi says it shelters.

Pakistan has opposed some of these projects before, saying they violate a World Bank-mediated treaty on the sharing of the Indus River and its tributaries upon which 80 percent of its irrigated agriculture depends.
