KYIV, Aug 18 - President Volodymyr Zelenskyy said Sunday the daring military incursion into Russia’s Kursk region aims to create a buffer zone to prevent further attacks by Moscow across the border.

It was the first time Zelenskyy clearly stated the aim of the operation, which was launched on Aug. 6. Previously, he had said the operation aimed to protect communities in the bordering Sumy region from constant shelling.

Zelenskyy said “it is now our primary task in defensive operations overall: to destroy as much Russian war potential as possible and conduct maximum counteroffensive actions. This includes creating a buffer zone on the aggressor’s territory -– our operation in the Kursk region,” he said in his nightly address, The Associated Press reported.

This weekend, Ukraine destroyed a key bridge in the region and struck a second one nearby, disrupting supply lines as it pressed a stunning cross-border incursion that began Aug. 6, officials said.

Pro-Kremlin military bloggers acknowledged the destruction of the first bridge on the Seim River near the town of Glushkovo will impede deliveries of supplies to Russian forces repelling Ukraine’s incursion, although Moscow could still use pontoons and smaller bridges. Ukraine’s air force chief, Lt. Gen. Mykola Oleshchuk, on Friday released a video of an airstrike that cut the bridge in two.

Less than two days later, Ukrainian troops hit a second bridge in Russia, according to Oleshchuk and Russian regional Gov. Alexei Smirnov.

As of Sunday morning, there were no officials giving the exact location of the second bridge attack. But Russian Telegram channels claimed that a second bridge over the Seim, in the village of Zvannoe, had been struck.

According to Russia’s Mash news site, the attacks left only one intact bridge in the area. The Associated Press could not immediately verify these claims. If confirmed, the Ukrainian strikes would further complicate Moscow’s attempts to replenish its forces and evacuate civilians.

Glushkovo is about 12 kilometers (7.5 miles) north of the Ukrainian border, and approximately 16 kilometers (10 miles) northwest of the main battle zone in Kursk. Zvannoe is located another 8 kilometers (5 miles) to the northwest.

Kyiv previously has said little about the goals of its push into Russia with tanks and other armored vehicles, the largest attack on the country since World War II, which took the Kremlin by surprise and saw scores of villages and hundreds of prisoners fall into Ukrainian hands.

The Ukrainians drove deep into the region in several directions, facing little resistance and sowing chaos and panic as tens of thousands of civilians fled. Ukraine’s Commander in Chief, Gen. Oleksandr Syrskyi, claimed last week that his forces had advanced across 1,000 square kilometers (390 square miles) of the region, although it was not possible to independently verify what Ukrainian forces effectively control.

In his remarks on creating a buffer zone, Zelenskyy said Ukrainian forces “achieved good and much-needed results.”

Analysts say that although Ukraine could try to consolidate its gains inside Russia, it would be risky, given Kyiv’s limited resources, because its own supply lines extending deep into Kursk would be vulnerable.

The incursion has proven Ukraine’s ability to seize the initiative and has boosted its morale, which was sapped by a failed counteroffensive last summer and months of grinding Russian gains in the eastern Donbas region.

For his part, Russian President Vladimir Putin said while visiting China in May that Moscow’s offensive that month in Ukraine’s northeastern Kharkiv region was aimed at creating a buffer zone there.

That offensive opened a new front and displaced thousands of Ukrainians. The attacks were a response to Ukrainian shelling of Russia’s Belgorod region, Putin said.

“I have said publicly that if it continues, we will be forced to create a security zone, a sanitary zone,” he said. “That’s what we are doing.”

Ukraine’s move into Kursk resembled its lightning operation from September 2022, led by Syrskyi, in which its forces reclaimed control of the northeastern Kharkiv region after taking advantage of Russian manpower shortages and a lack of field fortifications. (ap/ez)
