It's a 48-year-old argument that's once again got nuclear-armed neighbours in a showdown and locals on both sides of the border fearing the worst. India blames Pakistan for Kashmir's worst terror attack in years: the killing of 26 tourists, with non-Muslims singled out and murdered in front of loved ones. Islamabad denies involvement. It blames New Delhi for the March terror attack on a train in Baluchistan. There, too, 26 people were killed, with the matching tolls fuelling speculation and conspiracy theories. So what did happen?

Why now? And how to break the cycle of repeated tensions over Kashmir, a region carved up at independence from Britain in 1947 and whose borders remain disputed to this day?

How far could it go this time? India has suspended a vital 1960 treaty that manages water use between the two neighbours, a treaty that had held through three subsequent wars. Why is this time different?

Then there's Kashmir itself, which on the Indian side lost its partial autonomy back in 2019. What's changed inside the Muslim-majority region since? And what's changed on the Pakistani side after what had been a period of relative détente? Is this really a fight orchestrated by respective capitals?
