The nuclear-armed rivals ramped up tit-for-tat diplomatic offensive following a deadly attack on tourists in Pahalgam.

The clash took place just days after a terror attack killed 26 people on the Indian side of the disputed region, raising tensions between the two nuclear-armed nations.

An attack on tourists in India's Himalayan territory of Kashmir this week sparked a new crisis between nuclear armed South Asian neighbours India and Pakistan, with New Delhi blaming militants with "cross-border linkages" for the killings.
