Though aerial fighting between the nuclear-armed rivals does not appear to be sustained and ongoing at this point, Pakistan has closed its airspace for nearly all flights on Wednesday, in the aftermath of the Indian cross-border strikes which killed at least 26 people – including a 3-year-old girl – and wounded at least 46 other people, Pakistani authorities say based on the latest revised death toll. International carriers have also canceled flights to the region, and access to social media, including X, was temporarily blocked in Pakistan amid the assault. Heavy shelling is being reported along the Line of Control (LOC) separating the historic enemy nations.

The true casualty toll could be higher, as a Pakistani militant chief targeted in the attacks on 'terror camps' said 10 of his relatives, including five children, were killed. The Islamist group Jaish-e-Mohammed (JeM) was one of the groups targeted, and its leader Masood Azhar said his older sister, brother-in-law, his nephew and niece are among the dead.

Pakistan says that civilians were harmed and targeted that mosques were hit across six locations in its territory, and so has the right to respond to aggression. Indian has said it attack nine terror sites, but has been careful to stipulate these were non-military locations, and is now seeking de-escalation.

Pakistani Prime Minister Shehbaz Sharif has ordered his armed forces to prepare a plan for "self-defense" with "corresponding actions" in order "avenge the loss of innocent Pakistani lives". The order was issued after an emergency National Security Commitee (NSC) meeting on Wednesday.

"Pakistan reserves the right to respond, in self-defense, at a time, place, and manner of its choosing to avenge the loss of innocent Pakistani lives and blatant violation of its sovereignty," the NSC readout said. "The Armed Forces of Pakistan have duly been authorized to undertake corresponding actions in this regard."

Pakistan's Government Security Committee has charged that India has "ignited an inferno in the region". These do indeed seem to be fighting words.

What India has dubbed 'Operation Sindoor' is intended to be limited, Indian leaders have said, but it's highly questionable whether it was a 'success' - given that India lost at least one or possibly up to five fighter jets.

Social media images and footage, including issued by AFP, appear to confirm that aircraft were downed but without further clear or verified details:

Pakistani military sources later said they shot down five Indian Air Force jets and one drone in "self-defense," claiming three Rafale jets – sophisticated multi-role fighters made in France – were among those downed as well as a MiG-29 and an SU-30 fighter.

A local resident and government official told CNN that an unidentified fighter aircraft had crashed on a school building in Indian-administered Kashmir.
