Ukraine recaptured more than 700 square kilometers of territory in the east and south during a lightning counteroffensive, a Ukrainian general said Thursday, giving the first official assessment of the operation.

These victories, if confirmed and sustained, would be a major blow to Russia, which Western intelligence says has suffered huge losses. It will also be a major boost for Kyiv, which is eager to show its Western partners that it can make a difference on the ground through force and that it deserves continued support.

Some of the biggest victories appear to have been achieved this week during a surprise Ukrainian counteroffensive in eastern Ukraine’s Kharkiv region.

At a briefing, Brigadier General Oleksiy Gromov said that during the ongoing operation, Ukrainian troops pushed back the occupiers by 50 km and recaptured more than 20 villages of the Kharkiv region.

The night before, Ukrainian leader Volodymyr Zelenskyi spoke about the “good news” on the battlefields in eastern Ukraine and thanked the three brigades for what he called their courage.
