The Indian military may attack Pakistan sometime in less than two weeks, Pakistani Foreign Minister Shah Mahmood Qureshi claimed citing “reliable intelligence.” The two nuclear powers had a major flare up of tensions in February.

“We have reliable intelligence that India is planning a new attack on Pakistan. As per our information this could take place between April 16 and 20,” Qureshi announced.

The minister, who was visiting his hometown of Multan on Sunday, told journalists that Pakistan shared its concerns with the five permanent members of the UN Security Council. The official would not elaborate on what evidence Islamabad has to back his claim, but indicated he was speaking on the instruction of Prime Minister Imran Khan.

Later on Sunday, Pakistan also summoned a Delhi envoy and lodged a protest against any potentially drastic steps. “Indian deputy high commissioner was summoned for demarche in line with Foreign Minister’s briefing of today and warned against any misadventure,” Pakistan’s Foreign Office spokesman Mohammad Faisal said in a tweet.

India would not immediately respond to the allegations.

Tensions between the nuclear-armed rival neighbors escalated this year after a suicide bombing attack killed dozens of Indian police troops in the disputed region of Kashmir in mid-February. Two weeks later, Indian warplanes conducted an air raid on Pakistani territory, targeting what India said was a training camp of the militant group which claimed credit for the attack.

An outraged Pakistan retaliated on the following day with its own bombing raid in the Indian-controlled part of Kashmir, which escalated into a clash between two nations’ air forces.
