Volodymyr Zelensky warns Russian skies "will effectively be closing" for foreign carriers

According to a Wall Street Journal report, Ukraine has been using armed unmanned aircraft to hit Russian oil-processing plants, crop-export harbors, and online-retail storage centers. The resulting disruptions have meant fuel rationing, billions of dollars in damage for marketplace vendors, falling grain exports, bank-share selloffs, and frequent temporary shutdowns of airports. President Vladimir Putin acknowledged the aggregate cost—around $25 billion, by his estimate—but suggested it was not decisive for Russia. In remarks on Tuesday, Ukrainian President Volodymyr Zelensky warned that foreign carriers and their insurers still serving Russian destinations could expect the skies there to become ever more unusable as drone operations continue.
