Pakistan is preparing international legal action over India's suspension of a key river water-sharing treaty, a government minister told Reuters, as tensions intensify between the neighbours following an attack on tourists in India-administered Kashmir.

For the first time, India on Wednesday suspended the World Bank-mediated Indus Waters Treaty of 1960 that ensures water for 80% of Pakistani farms, saying it would last until "Pakistan credibly and irrevocably abjures its support for cross-border terrorism".

NEW DELHI — A deadly attack on tourists in Indian-controlled Kashmir has again moved India and Pakistan closer to war as the two rivals downgraded diplomatic and trade ties, closed the main border crossing and revoked visas for each other’s nationals.
