India quickly accused Pakistan of supporting cross-border terrorism, an allegation Islamabad has fiercely denied. In response, New Delhi suspended the Indus Waters Treaty – a key water-sharing agreement dating back to 1960 – and downgraded diplomatic ties by expelling Pakistani diplomats and revoking visas of Pakistan nationals. India also closed Attari-Wagah border crossing and advised its citizens against traveling there (Reuters +4 The Guardian +4 Wikipedia =+4 per page).
Wikipedia Pakistan responded with reciprocal measures, expelling Indian diplomats, suspending trade and visa services, and closing its airspace to Indian aircraft. Islamabad suspended the 1972 Shimla Accord that laid out bilateral relations; further, any disruptions to water flows on the Indus River system would be treated as acts of war by Islamabad.
