Russia Vows More Strikes on Ukraine, Warns Diplomats in Kyiv of Danger

Russia said it will intensify strikes on Ukrainian military and industrial infrastructure, escalating tensions after President Volodymyr Zelenskyy vowed to target Russian oil refineries in response to attacks on Ukraine's energy sites. The Russian Defense Ministry cited Zelenskyy's Reuters interview, while Moscow warned foreign diplomats in Kyiv of "mortal danger." Russian forces struck Kyiv's Northern bridge for a second time, killing one person and injuring six, according to Ukrainian officials. German Chancellor Friedrich Merz arrived in Kyiv on Sunday to reaffirm support, as Russia's foreign ministry urged foreign nationals to avoid travel to Ukraine. The escalation follows recent drone strikes and attacks on civilian infrastructure, with Zelenskyy calling for accountability against Russian "terror."
