President Vladimir Putin visited Russia’s Kursk region for the first time since Moscow claimed that it drove Ukrainian forces out of the area last month, the Kremlin said Wednesday.

Putin visited the region bordering Ukraine the previous day, according to the Kremlin.

Ukrainian forces made a surprise incursion into Kursk in August 2024 in one of their biggest battlefield successes in the more than three-year war. The incursion was the first time Russian territory was occupied by an invader since World War II and dealt a humiliating blow to the Kremlin.

Since the end of 2023, Russia has mostly had the advantage on the battlefield, with the exception of Kursk.

Putin has effectively rejected recent U.S. and European proposals for a ceasefire. Russian Foreign Minister Sergey Lavrov on Wednesday accused Kyiv’s allies of seeking a truce “so that they can calmly arm Ukraine, so that Ukraine can strengthen its defensive positions.”

North Korea sent up to 12,000 troops to help the Russian army take back control of Kursk, according to Ukraine, the U.S. and South Korea. Russia announced on April 26 that its forces had pushed out the Ukrainian army. Kyiv officials denied the claim.

The Ukrainian Army General Staff said Wednesday that its forces repelled 13 Russian assaults in Kursk. Its map of military activity showed Ukrainian troops holding a thin line of land hard against the border but still inside Russia.

Putin’s unannounced visit appeared to be an effort to show Russia is in control of the conflict, even though its full-scale invasion of its neighbor has been slow and costly in terms of casualties and equipment.

Video broadcast by Russian state media showed that Putin visited Kursk Nuclear Power Plant-2, which is still under construction, and met with selected volunteers behind closed doors.

Many of the volunteers wore clothes emblazoned with the Russian flag and the Latin letters “Z” and “V”, which are symbols of Russia’s invasion of Ukraine.

“What you are doing now during this difficult situation for this region, for this area, and for the country, will remain with you for the rest of your life,” Putin said as he drank tea with the volunteers.

Ukraine’s surprise thrust into Kursk and its ability to hold land there was a logistical feat, carried out in secrecy, that countered months of gloomy news from the front about Ukrainian forces being pushed backward.

Kyiv’s strategy aimed to show that Russia has weaknesses and that the war isn’t lost.

It also sought to distract Russian forces from their onslaught in the eastern Donetsk region of Ukraine.The move was fraught with risk. Analysts noted that it could backfire and open a door for Russian advances in Ukraine by further stretching Ukrainian forces that are short-handed along the roughly 620-mile front line.

The incursion didn’t significantly change the dynamics of the war.
