India summoned Pakistan's top diplomat in Delhi, Saad Ahmad Warraich and formally handed him a persona non grata notice for its military diplomats. India's action comes in the wake of the brutal attack by militants on tourists in Jammu and Kashmir's Pahalgam on Tuesday that left 26 people dead and several others injured.

India has suspended its Indus Waters Treaty with Pakistan and taken other measures against its nuclear-armed neighbor following the killing of 26 Indian tourists in Pahalgam, Kashmir, in what India described as a terrorist attack.
