Following Tuesday's massacre of 26 mostly Indian tourists, hostilities have intensified between India and Pakistan over the hotly contested Kashmir region.

"If they stop water, all of this will turn into the Thar desert, the whole country," one farmer said. "We'll die of hunger."

Indian Prime Minister Narendra Modi has vowed to pursue the attackers to "the ends of the earth" and said that those who planned and carried it out "will be punished beyond their imagination". Calls have also grown from Indian politicians and others for military retaliation against Pakistan.
