Ukraine said Wednesday that it had destroyed Russian pontoon bridges with U.S.-made weapons to defend its incursion into Russia's Kursk region, while Moscow said its forces had halted Kyiv's advance there and had gained ground in eastern Ukraine.
Kyiv has announced a string of battlefield successes since it crossed unexpectedly into the Kursk region on August 6. Moscow has steadily inched forward in eastern Ukraine, pressuring troops worn down by 2½ years of fighting.
Ukrainian President Volodymyr Zelenskyy said Ukraine's military was responding to the Russian push by strengthening its forces around Pokrovsk, the focus of Russian advances in eastern Ukraine.
Speaking in one of his regular televised addresses, he also urged Kyiv's allies to honor commitments to send munitions for use by the Ukrainian armed forces.
"This is fundamental for defense," he said.
Ukraine has closely guarded its overarching aims in the Kursk region but said it had carved out a buffer zone from an area Russia has used to pound targets in Ukraine with cross-border strikes.
A video posted by Ukrainian special forces showed strikes on several pontoon crossings in the Kursk region, where Russia has reported that Ukraine has destroyed at least three bridges over the Seym River as it seeks to hold the captured land.
"Where do Russian pontoon bridges 'disappear' in the Kursk region? Operators ... accurately destroy them," Ukraine's Special Operations Forces said on the Telegram messenger.
Ukraine's Foreign Ministry has said Kyiv has made bigger territorial gains in the Kursk region than Moscow has made in Ukraine this year. Russia has called the incursion an escalation.
Ukraine smashed through the Russian border in the Kursk region on August 6 in an attempt to force Moscow to divert troops from the rest of the front, though Russian forces have continued to advance in recent days.
Russia took the settlement of Zhelanne, which lies less than 20 km to the east of the transport hub Pokrovsk, according to the Russian defense ministry.
Both sides reported being targeted by major drone attacks. Ukraine said it intercepted 50 of 69 drones launched by Russia; Moscow said its air defenses destroyed 45 drones over Russian territory, including 11 over the Moscow region.
Reporting back to Moscow, Major General Apti Alaudinov, commander of Chechnya's Akhmat special forces and the deputy head of the defense ministry's military-political department, said Russia had stalled the Ukrainian incursion.
"We halted them and started pushing them back," Alaudinov told Rossiya state television. He said Ukrainian forces were regrouping and could soon launch a new attack, though he gave no further details.
Russia has repeatedly said the Ukrainian offensive has been halted. Ukraine has kept touting gains, saying it has captured 92 settlements over an area of more than 1,250 square km.
The Ukrainian military, which has not made significant gains on its own soil since late 2022, has gotten a much needed morale boost from the incursion.
Roman Kostenko, secretary of the Ukrainian parliament's national defense committee, said Russia's priority remained to capture the Donetsk region despite the incursion and that it was not pulling forces from near Pokrovsk to act as reinforcements.
Mykola Bielieskov, a research fellow at the Ukrainian National Institute for Strategic Studies, a think tank in Kyiv, said attacks on bridges and pontoons would help Ukraine build a defensive line along the river.
"This is an opportunity to make it more stable, systemic, ready to repel Russian attacks," he said in remarks on national television.
Reuters confirmed that all of the strike locations of pontoon bridges shown in the video were on or near the Seym River in the Kursk region.
The video also showed drone strikes on military trucks and other locations described as a Russian munitions warehouse and an electronic warfare complex in the region. Other locations or the date when the video was filmed could not be independently verified.
Separately, Reuters was able to verify that at least one pontoon crossing was apparently destroyed.
The Ukrainian statement said U.S.-manufactured HIMARS rocket systems had been used as part of operations to disrupt Russian logistics in the Kursk region, Kyiv's first official statement acknowledging its use of the weapon during its incursion.
Washington has not commented directly on the use of U.S.-made weapons in the Kursk region, while saying U.S. policies have not changed and Ukraine was defending itself from Russia's ongoing all-out invasion.
While allies have barred Ukraine from conducting long-range strikes with Western weapons inside Russia, they have allowed Kyiv to use them to hit border areas since Russia's new offensive on Kharkiv region this spring.
