India announced a raft of measures to downgrade its ties with Pakistan on Wednesday, a day after suspected militants killed 26 men at a tourist destination in Kashmir in the worst attack on civilians in the country in nearly two decades.

India's External Affairs Ministry said the Indus Water Treaty will be suspended after an attack in Kashmir left over two dozen dead.

India also cancels some visas held by Pakistanis and expels diplomats as tensions rise following the killing of tourists.
