In response to the April 22 terrorist attack in Pahalgam that claimed 26 lives, India on April 23 took a series of strong diplomatic and strategic measures. These included closing the Wagah-Attari border, suspending the Indus Water Treaty, and declaring all Pakistani nationals—including diplomats and defence personnel— persona non grata.

IndiGo said that the sudden closure of Pakistani airspace has disrupted several of its international flight operations.
