Russia withdraws troops after Ukraine encircles key city

After being encircled by Ukrainian forces, Russia pulled troops out Saturday from an eastern Ukrainian city that it had been using as a front-line hub. It was the latest victory for the Ukrainian counteroffensive that has humiliated and angered the Kremlin.

Russia’s withdrawal from Lyman complicates its internationally vilified move to annex four regions of Ukraine and paves the way for Ukrainian troops to potentially push further into land that Moscow now illegally claims as its own.

The fighting comes at a pivotal moment in Russian President Vladimir Putin’s war. Facing Ukrainian gains on the battlefield — which he frames as a U.S.-orchestrated effort to destroy Russia — Putin this week heightened his threats of nuclear force and used his most aggressive, anti-Western rhetoric to date.

Russia’s Defense Ministry claimed to have inflicted damage on Ukrainian forces in battling to hold onto Lyman, but said outnumbered Russian troops were withdrawn to more favorable positions. The Russian announcement came soon after Ukraine’s air force said it had moved into Lyman and the Ukrainian president’s chief of staff posted photos of a Ukrainian flag being hoisted on the town’s outskirts.
