"We think it lays out a strategy and a plan that can work," she said. Miller told a news briefing Blinken had learned about the plan during a visit to Kyiv and shared the ambassador's assessment.

The capture of Ukrainsk underscored Russia’s steady advances in the Donetsk region. Ukraine is trying to counter with strikes on Russian military infrastructure.
