Ukrainian Forces Ambush Russian Convoy in Kursk, Kremlin Declares Emergency

Kursk, Russia — Ukrainian forces conducted an overnight ambush on a Russian convoy approximately 25 miles inside the international border in Russia’s Kursk province. The Kremlin has declared a federal emergency and announced the deployment of additional forces to counter the four-day incursion, which has significantly undermined its credibility.

A video circulated by Russian military bloggers showed a destroyed convoy, with bodies visible inside some trucks, on the E38 east-west highway at Oktyabrskoe. This location is deeper inside Russia than any previously confirmed fighting since Ukrainian forces crossed the border on Tuesday.

The attack, reminiscent of Ukrainian tactics used against Russian troops besieging Kyiv in the early weeks of the war, demonstrates an effective hit-and-run strategy. However, the incursion is likely to provoke an escalating response from the Kremlin, and its overall outcome remains uncertain.

Russia’s defense ministry announced at lunchtime that it was transferring military reserves to the Kursk region, including Grad rockets, artillery, and tanks, according to the Interfax news agency. A video released by Zvezda, the official Russian military media, showed a convoy of lorries carrying armored vehicles down a highway.

Alexei Smirnov, the acting governor of Kursk oblast, stated that Moscow had declared a state of federal emergency in the morning. He urged residents to “stay calm and keep up your fighting spirit, support each other, do not give in to panic and despondency.” So far, 3,000 Russian civilians have been evacuated away from the fighting.

Meanwhile, 10 Ukrainians were reported killed and 35 injured after a Russian missile struck a supermarket during the day in the Ukrainian town of Kostiantynivka, about 8 miles from the eastern frontline in Donetsk. “Russian terrorists hit an ordinary supermarket and a post office. There are people under the rubble,” Ukrainian President Volodymyr Zelenskiy said.

Ukraine was able to burst through a lightly defended Kursk border on Tuesday morning with several hundred troops, according to Russia. Ukrainian forces have engaged in fast-moving maneuver warfare, a type of combat rarely seen during the war in Ukraine, which has been largely dominated by fortified trenches and heavy mining, preventing breakthroughs.

The fast-moving fighting and limited sources of information make it hard to determine the exact location of the frontlines in the sector. Unlike during last year’s failed summer counteroffensive, Ukraine’s military has not released triumphant videos of the capture of small villages that give clues to the enemy.

Russia’s semi-independent military bloggers, the principal source of information about the incursion, report that Ukraine has captured the west of Sudzha, 6 miles from the border, and pushed up three roads to the north-east, north, and north-west of the town, including where a railway and likely supply route runs to the Russian city of Belgorod in the east.

Rybar, a Russian military blogger, said Ukraine’s tactics involved using its armored vehicles to head towards Russian positions and using a third of them to tie down the defenders while the rest were “bypassing it, entering nearby settlements and setting up ambushes.” As a result, Kyiv’s control of the territory in which it was operating is limited, the blogger and commentator said.

Ukraine’s leaders have largely avoided commenting on the attack, the first time their country’s regular armed forces have broken through the international border, though on Thursday night Zelenskiy alluded to developments.

“Russia brought the war to our land and should feel what it has done,” he said in his nightly address. But Ukraine’s intentions remain unclear as the battle develops.

Hanna Shelest, a senior fellow with the Center for European Policy Analysis, said that Ukraine had regained some of the initiative with the surprise attack and that it had “a psychological effect in that it has weakened the image of Vladimir Putin as a strongman president who protects his own people.”

Kyiv’s likely military hope, Shelest added, was likely to be that “Russian reserves would be moved to make Ukraine’s situation in the east easier,” though she acknowledged there had not been any confirmed movement of troops from the Donbas, where Russia’s larger army has been making slow but steady gains for weeks.

John Foreman, a former UK defense attaché to Moscow and Kyiv, said he believed the Kursk operation was “not without strategic risk” because it could also divert scarcer Ukrainian resources from already lengthy frontlines. “We don’t know the Ukrainian units involved, their strength, logistics, or combat and aviation support. Zooming out territorial gains are so far modest,” he added.

Attacks inside Russia had been considered politically fraught for Ukraine. Its western allies, led by the US, have refused to allow highly valued western weapons to be used to strike into Russia’s internationally recognized borders for fear of wider escalation. However, this week the White House has been relatively supportive, which Shelest said would be a relief to Ukraine’s leaders.

In April, the US publicly criticized Ukraine for targeting Russian oil refineries, fearing the impact on energy prices and inflation. But on Thursday, Sabrina Singh, the press secretary for the Pentagon, said Ukraine’s incursion into Russia was “consistent with our policy,” though it also remained the case that “we don’t support long-range attacks” into Russia. Singh refused to define what was meant by long-range.
