Russia battled on Sunday to drive the last Ukrainian soldiers from western Russia, Russian officials said, after a seven-month incursion by Ukraine that aimed to distract Moscow's forces, gain a bargaining chip and rile President Vladimir Putin.

Without confirming the withdrawal with a statement, the General Staff of Ukraine's Armed Forces posted the latest battlefield maps on social media, which showed a complete retreat from Sudzha.

President Trump and President Vladimir V. Putin both claimed that Ukrainian forces were surrounded. Ukraine’s top military commander vowed to “hold the line.”
