India has described the April 22 massacre as a terror attack and blamed Pakistan for backing it, an accusation denied by Islamabad. India swiftly announced diplomatic actions against its archrival Pakistan, which responded with its own tit-for-tat measures.

India’s government said on Wednesday morning that it attacked Pakistan to bring the planners of last month’s attack on tourists in Kashmir to justice and because it had evidence that “further attacks against India were impending” and had to be deterred.
