Ukraine's recent incursion into Russia's Kursk region has significantly shifted the dynamics of the conflict, creating a 'real dilemma' for Russian President Vladimir Putin, according to U.S. President Joe Biden. Kyiv's forces have reportedly secured control over 74 settlements and advanced up to 30 kilometers into Russian territory. The strategic move aims to compel Russia to divert troops from Ukraine to defend its own borders. The Biden administration has maintained frequent contact with Ukrainian officials but insists it had no prior knowledge or involvement in the operation. U.S. and EU officials continue to express support for Ukraine, with additional military aid being provided. Meanwhile, the situation remains tense, with both sides reporting conflicting accounts of the battlefield status.
