India blames Pakistan for an attack on its tourists and threatens to disrupt Pakistani water supplies. Islamabad says that move would be an act of war.

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

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.
