Russia and Ukraine traded overnight strikes hours before an informal European Council summit in Dublin: Ukraine hit a major oil refinery in Russia's Volgograd region, sparking a fire, while Russia's missiles struck a medical facility in Kyiv. U.S. envoys Jared Kushner and Steve Witkoff met Putin in Moscow and Zelenskyy in Dublin about a peace settlement, and EU leaders are expected to discuss the war and who should speak for Europe at peace talks.
