Addressing a news conference in Multan, Qureshi said there is "reliable intelligence that India is readying for another act of aggression" against Pakistan.
The statement further added that "This public gimmick appears to be a call to Pakistan-based terrorists to undertake a terror attack in India".
Qureshi further added that the information has been shared with Prime Minister Imran Khan, global community, and permanent members of the UN Security Council. In the dogfight, the Indian Air Force said it had shot down a Pakistani fighter jet while losing one of its own.
The Ministry of External Affairs did not issue an official response, but sources said Pakistan was trying to create war hysteria.
The foreign minister added that Pakistan has informed all five permanent members of United Nations Security Council (UNSC), including China, France, United States, United Kingdom and Russian Federation about Indian plans to disrupt the peace of the region. "This action could possibly take place between the 16th to the 20th of April".
The Foreign Policy report serves a blow to Prime Minister Narendra Modi's government just days before the beginning of India's general elections, in which the premier is seeking another term in office. The Pakistan People Party (PPP) accused the government of using war threat by India to hide its failures.
Indian Defence Ministry's spokesman Lt. Col. Devender Anand said in a statement: "Around 7.30 am, Pakistan initiated the attack violating the ceasefire agreement".
Satellite images showing little sign of damage have also case doubt on the success of Indian air strikes on a camp of the Jaish-e-Mohammed militant group in northwestern Pakistan.
Pakistan on Sunday summoned Indian deputy High commissioner to Foreign Office to lodge a protest against Indian aggression.
Pakistan had closed its airspace amid the standoff with India but most commercial air traffic has since resumed and major airports have opened. The first hundred were released on Sunday.
Because relations are so rocky, prisoners who have completed jail terms, many of them fishermen convicted of straying into each other's territory, often languish in prison for months, if not years, afterwards.
The released prisoners were taken to the Karachi Cantonment Railway Station under heavy security, where they boarded the Allama Iqbal Express for Lahore, The Express Tribune reported.
