The United States is stepping up pressure on India and Pakistan to avoid conflict in Kashmir after a tourist massacre in an Indian-administered area of the divided territory last week.

Indian Prime Minister Narendra Modi has vowed to pursue the assailants behind last month's attack on tourists in Kashmir to the "ends of the earth". India says two of the three "terrorists" involved in the attack were from arch-enemy Pakistan,

Pakistan accused India on Wednesday of planning an imminent military strike using a terror attack that killed 26 Indian tourists in the disputed Kashmir region last week as a "false pretext" to hit out at its neighbor.
