Russia strikes Kyiv overnight; Poland scrambles jets; US weighs diesel export ban

Russia conducted a night strike on Kyiv, prompting Poland to scramble fighter jets in response. Separately, the US is considering a 90-day ban on fuel oil exports, which could tighten global diesel supplies. The strike continues Russia's pattern of attacks on Ukrainian cities, while the export ban, if enacted, would mark a significant shift in US energy policy with global market implications.
