India accused Pakistan of backing the militants who carried out the massacre, a charge Islamabad denied. After Wednesday's strikes in Pakistan, both sides exchanged heavy fires along their de facto border in the disputed territory of Kashmir. Dozens of civilians were killed on both sides in heavy shelling, the two countries said.

The Indian army said on Saturday that Pakistan was continuing its "blatant escalation" with drone strikes and using other munitions along India's western border, and its "enemy designs" would be thwarted.

The truce came after several days of the countries’ most expansive fighting in decades. One Indian official said the country would “deal strongly” with any violations.
