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

SRINAGAR, India — India blamed Pakistan on Wednesday for a militant attack that killed 26 people in Indian-held Kashmir, downgrading diplomatic ties and suspending a crucial water-sharing treaty that has withstood two wars between the nuclear-armed rivals.

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