In response, Pakistan also announced shutting its airspace to all Indian airlines and suspended trade with New Delhi including through third countries. Islamabad also rejected India's suspension of the Indus Waters Treaty and said any measures to stop the flow of water belonging to Pakistan under the pact will be seen as an "act of war".

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.

U.S. President Donald Trump said he is close to both India and Pakistan, but declined to mediate in the Kashmir conflict. Referring to the historical nature of the dispute, Trump expressed confidence that both nations would eventually resolve their issues.
