Over the weekend, Ukraine's Zaporizhzhia nuclear power plant — the largest such plant in Europe — came under fire. Who was behind it remains unclear: Ukraine and Russia blame each other for the attacks. What is clear, is that the strikes are coming nearer to and have already damaged some critical parts of the sprawling nuclear complex.
An NPR analysis of satellite imagery and posts to Twitter, Telegram and YouTube over the past month show how an escalating conflict at the plant is drawing ever closer to critical safety systems and radioactive materials, ratcheting up the chance of a nuclear disaster.
