GUJRAT, Pakistan - A bitter dispute over limited water resources is fueling India-Pakistan tensions at a time when the South Asian neighbors are trying to rebuild trust and resume peace talks.

It's a long-running feud that has worsened in recent months as a dry spell focuses attention on Pakistan's growing water shortage. Three days of talks in March ended with both sides trading barbs and failing to reach a resolution.

The issue was raised Thursday when the leaders of the two countries met at a regional summit in Bhutan and agreed on the need to normalize relations, the Pakistani side said.
