LAHORE, Pakistan, April 2 (UPI) -- Disputes over water from the Indus River are the latest stresses to the shaky relationship between nuclear-armed foes Pakistan and India.
Pakistani officials say India is taking more than its fair share of water upstream, creating problems for Pakistani farmers.
Pakistani Foreign Minister Shah Mahmood Qureshi told The Wall Street Journal that the water issue was straining the relationship with India.
"Water I see emerging as a very serious source of tension between Pakistan and India," he said.
Pakistan said it would launch a formal challenge to plans by India to build a hydroelectric dam on a tributary to the Indus River. New Delhi said it has the legal right to build the dam, blaming Pakistani water shortages on weather issues and mismanagement.
Pakistan has its own plans for hydroelectric power from the river. Islamabad complains the project in India would reduce the flow of the Indus River by more than 30 percent.
A bilateral treaty signed in the 1960s governs water access from the Indus River and its tributaries.
