Gunfire exchanges between Pakistani and Indian military forces continued for a second day on Saturday across the Kashmir border between the two nations.

Pakistan called India's actions “irresponsible" and canceled visas for Indian nationals, suspended all trade with India and closed its airspace to Indian aircraft.

Relations between India and Pakistan are cratering following a deadly militant attack in Indian-administered Kashmir that has sparked tit-for-tat reprisals and raised fears of another military escalation between the nuclear-armed rivals.
