A carrier mounted with India’s ballistic missile Agni move past the saluting base in New Delhi on January 26. Indian threat of a missile barrage and Pakistani reaction prompted world powers to intervene to de-escalate the recent tensions between the neighbours.ReutersA reported Indian threat to hit at least six targets with missiles and Pakistani vow to retaliate with “three times” the force set off alarm bells in western capitals triggering their intervention to prevent the catastrophe and de-escalate the tensions in the wake Indian bombing of Balakot to avenge Pulwama terror strike and Pakistani raid across the Line of Control in Jammu and Kashmir, media reports say. During the conflict, New Delhi said it shot down a Pakistani F-16 fighter jet in a skirmish and lost a MiG-21 plane whose pilot Abhinandan Varthaman was taken alive after ejecting from the burning plane and was later returned to India.Though Indian officials have denied knowledge of such a missile threat, a Reuters report said a Pakistani minister and a western diplomat separately confirmed the threat and avowed retaliation, a report in The Hindu said. The sources did not specify who delivered the threat or who received it. “We said if you will fire one missile, we will fire three,” the Pakistani minister said.India’s National Security Adviser Ajit Doval had reportedly spoken with Pakistan’s ISI chief Asim Munir over a secure line hours after the dogfight over the LoC to tell him India was not going to back down. Doval told Munir that India’s fight was with the militant groups that operated from Pakistani soil and it was prepared to escalate, a government source told Reuters.A Pakistani government minister and a Western diplomat in Islamabad separately confirmed a specific Indian threat to hit six targets inside Pakistan, according to the report. They did not specify who delivered the threat or who received it, but the minister said Indian and Pakistani intelligence agencies “were communicating with each other during the fight, and even now they are communicating with each other”.Pakistan said it would counter any Indian missile attacks with many more launches of its own, the minister told Reuters, speaking on condition of anonymity. “We said if you will fire one missile, we will fire three. Whatever India will do, we will respond three times to that,” the Pakistani minister said.Reports of the threat and counter threat set western diplomatic circles buzz and US National Security Advisor John Bolton was forced to intervene despite his preoccupation with President Donald Trump’s summit with North Korean leader Kim Jong-un in Vietnam. Washington, Beijing, and London reportedly joined hands to put pressure on the two countries to back down.

Pompeo spoke to Doval, the Indian and Pakistani Foreign Ministers Sushma Swaraj and Shah Mahmood Qureshi, respectively, Palladino said.US Indo-Pacific Command Admiral Phil Davidson told reporters in Singapore last week that he had separately been in touch with the Indian navy chief, Admiral Sunil Lanba, throughout the crisis. On the morning of Feb 28, Trump told reporters in Hanoi that he expected the crisis to end soon. “They have been going at it and we have been involved in trying to have them stop. Hopefully, that is going to be coming to an end.”The Pakistani minister said China and the United Arab Emirates (UAE) also intervened in the matter. The government of the UAE said Abu Dhabi Crown Prince Sheikh Mohammed bin Zayed al Nahyan spoke to both Prime Minister Narendra Modi and Pakistan Prime Minister Imran Khan. His announcement in Pakistan’s parliament that the Indian pilot would be released helped thaw the situation further, and Abhinandan was sent back the next day. “I know last night there was a threat there could a missile attack on Pakistan, which got defused,” Khan said. “I know, our army stood prepared for retaliation of that attack.”The two countries have gone to war three times since they gained independence in 1947, the last time in 1971. The two armies are trading fire along the line of control that separates them in Kashmir, but the tensions appear contained, reports say.
