"Both are under arrest, and we are treating them with dignity", Ghafoor said.
There was no reply from Modi, but India acknowledged one of its air force planes was "lost" in skirmishes with Pakistan and that its pilot was "missing in action". The calls were reportedly made after Pakistan violated the Geneva Convention by releasing a video showing the pilot tied up on social media. He appeared in good health as he was questioned about his hometown, his aircraft and his mission.
This came shortly after Pakistan said its air force shot down two Indian warplanes after they crossed the boundary between the two nuclear-armed rivals in the disputed territory of Kashmir, and captured two Indian pilots.
The Pakistani regulator said in a tweet: "Civil Aviation Authority of Pakistan has officially closed its airspace until further notice".

"Pakistan's plan was that there should be no casualties or damage, only to show Pakistani capability", said Khan. "One of the aircraft fell inside AJ&K while other fell inside IOK [Indian occupied Kashmir]", Pakistan army spokesman Maj.

Residents on both sides of the de-facto frontier, the so-called Line of Control, said there were exchanges of fire between the two sides through the night into Wednesday morning. Both sides again presented battling narratives about what sort of targets were struck, with Pakistan trying to make clear that its response was proportional retaliation for India's strikes.
After the Indian planes were downed Wednesday, Kahn said in a televised speech that the two nations should settle their dispute with diplomacy.
Lt. Col. Devender Anand, an Indian army spokesman, said Pakistani soldiers targeted dozens of Indian military positions across the Line of Control throughout the night.
