Last week, the Indian government faced embarrassment when a Foreign Policy magazine report citing senior U.S. defence officials stated that none of Pakistan's F-16 jets had been shot down by the Indian Air Force ─ contrary to India's claims ─ on Fen 27, when tensions between both countries had spiked in the aftermath of the Pulwama attack.
India's Foreign Ministry spokesman Raveesh Kumar, in a statement posted on Twitter, dismissed as "irresponsible and preposterous" the comments made by Qureshi. If the United States report turns out to be true, it would be a further blow to Prime Minister Narendra Modi, who had said that India had taught Pakistan a lesson, ahead of elections next week.
"We have reliable intelligence that India is planning a new attack on Pakistan. According to our information, the action could be taken between April 16-20", the paper quoted Qureshi as saying.
Pakistani Prime Minister Imran Khan has denied his country had any role in the attack.
Mr Qureshi said Pakistan had raised its concerns with the UN Security Council.
India struck the biggest terrorist training camp of terror group Jaish-e-Muhammed deep inside Pakistan on 26 February almost two weeks after the Pulwama terror attack in which 40 CRPF personnel were killed.

Twelve days later, on February 26, the Indian Air Force conducted a "surgical strike" on a JeM training camp in Balakot in Pakistan's Khyber Pakhtunwa province.
An Indian jet was brought down during the fight and its pilot captured when he ejected on the Pakistani side of the border. "BJP's attempt to win elections through whipping up war hysteria and false claims of downing a Pak F-16 has backfired with US Defence officials also confirming that no F-16 was missing from Pakistan's fleet".
Jaish had accepted responsibility for the suicide attack in Jammu and Kashmir's Pulwama in which 40 personnel of the Central Reserve Police Force were killed.
Sarwar said India stood isolated before the world community as its brutalities in Kashmir had been exposed and entire world admired Pakistan's stance on the regional peace and stability.
In a separate development on Sunday, the Indian Deputy High Commissioner was summoned to the Pakistani Foreign Ministry, which warned India against "any misadventure". Another attack on Pakistan will most certainly help the fortunes of the Bharatiya Janata Party, which has nearly exclusively been campaigning on the plank of "national security" and "nationalism".
India blamed the attack on a Pakistan-based militant group, a charge Islamabad denies.
