Russia said Saturday it had retaken two more villages from Ukrainian forces in its Kursk border region, where it has launched an offensive to wrest back seized territory.

Moscow has pushed this week to retake a large part of the land that Ukraine originally captured in its western Kursk region.

The Russian defence ministry said troops took control over the villages of Zaoleshenka and Rubanshchina—north and west of the town of Sudzha, the main town that Moscow reclaimed this week.

Russian leader Vladimir Putin a day earlier called on embattled Ukrainian troops in Kursk to “surrender,” while his US counterpart Donald Trump urged the Kremlin to spare their lives.

“If they lay down their arms and surrender, they will be guaranteed life and dignified treatment,” Putin said Friday.

Ukrainian President Volodymyr Zelensky said Friday that the situation in Kursk is “obviously very difficult.”

The Ukrainian army on Saturday published a map on social media that showed its troops had retreated west towards the border.
