Fighters of the Bratstvo Battalion, part of the Timur Special Unit of Ukraine’s military intelligence agency (HUR), captured three Russian servicemen and gave first aid to one of them, HUR reported on 19 October. They also found and destroyed Russian sabotage groups, HUR said, adding that counter-sabotage operations in the Zaporizhzhia direction are ongoing.

Russian forces have spent months trying to get closer to Zaporizhzhia, one of Ukraine’s largest cities. They may try to use the dried-up bed of the Kakhovka Reservoir to infiltrate north toward it as autumn fog and dense vegetation set in, the Institute for the Study of War reported on 26 September. Ukrainian troops are now clearing the area of Russian saboteurs trying to get into the rear of Ukrainian positions, according to HUR.

HUR’s video shows the fighting and the captures, with one dead Russian soldier blurred. At the end, a captured Russian says two of the three men in his group were killed by a “Baba Yaga,” the nickname Russian troops use for Ukraine’s heavy bomber drones.

HUR described what the Russian groups are trying to do:

“Using small sabotage groups, the enemy is attempting to penetrate deep into the rear positions of Ukraine’s Defense Forces, build up forces to destabilize the situation, disrupt logistics, and neutralize Ukrainian defenders’ combat crews.”

Russia seeks to bring the front closer to Zaporizhzhia

Russia’s objective in the Zaporizhzhia direction is to advance within artillery range of the city, hold forward positions, and protect its rear from Ukrainian strikes, the Institute for the Study of War noted.

In January, Russian forces were trying to capture Stepnohirsk and advance along the shore of the former Kakhovka Reservoir toward Zaporizhzhia. Taking the settlement would let Russian troops place long-range artillery or fiber-optic drones there to strike the city’s outskirts, Southern Defense Forces spokesperson Vladyslav Voloshyn told Ukrinform on 14 January.

On 22 September, Anastasiia Shevchenko, spokesperson for the Southern Forces Group, said there were no signs of preparations for a direct offensive on Zaporizhzhia and that Russian forces lacked the troops and means to advance directly toward the city.

Dense vegetation and limited visibility: combat on the reservoir bed

The Kakhovka Reservoir was a vast artificial body of water on the Dnipro River in southern Ukraine that supplied water to millions of people, as well as to agriculture and industry. On 6 June 2023, Russian forces blew up the Kakhovka Hydroelectric Power Plant, the Southern Operational Command reported.

After the dam was destroyed, the bed of the former reservoir quickly became overgrown with willows, poplars, and shrubs, creating a new battlefield. Ukrainian troops have fought there before.

In November 2025, fighters from the same Bratstvo unit carried out a reconnaissance and sabotage operation 7 kilometers from the shoreline of the former reservoir, HUR said. They found and eliminated Russian troops, then raised the Ukrainian flag over the islands there and took control of the area.

In April, the Bratstvo unit’s chief of staff, who goes by the call sign “Dyviziia,” described the conditions on an earlier raid across the reservoir bed:

“You’re just constantly moving through these thickets, with no way to figure out which direction to go. You can literally see everything just two meters ahead of you.”

Six people were killed in a Russian strike in the settlement of Nova Vodolaha in Kharkiv Oblast, including girls aged 1 and 11. Another 15 people were injured, including seven children, Kharkiv Oblast Governor Oleh Syniehubov said on 20 October. Russian forces struck a park with a drone while families with children were there, Ukraine’s Minister of Internal Affairs Ivan Vyhivskyi said.

Russian forces continue to attack Ukrainian cities, killing civilians and destroying civilian infrastructure. The Kharkiv Oblast Prosecutor’s Office has opened a war-crime investigation into the strike. The strike was aimed at people, Yurii Yurchenko, head of a police department in Kharkiv Oblast, said in a comment to Suspilne.

The 14-month-old girl was named Anhelina

The Russian drone circled the park several times before crashing, Yurchenko said. He said the drone struck a tree near a café, and the blast wave and shrapnel hit people at the establishment. The attack came at around 16:30, the prosecutor’s office said, adding that Russian forces had preliminarily used a Geran-3 drone.

The Russian strike killed three women, aged 28, 34 and 36, a man around 40 years old, and two girls, aged 14 months and 11 years, Syniehubov said in his statement.

The youngest girl, named Anhelina, was born in August 2025, Ukrainian President Volodymyr Zelenskyy said. Her mother, Inna, died in the hospital, he added.

Zelenskyy shows US senators photos of the aftermath the same day

Zelenskyy met with US Senators Richard Blumenthal and Thom Tillis, along with their colleagues from both parties and both chambers of Congress, according to a 19 October post on his social media accounts. During the meeting, he discussed the Russian attack in Kharkiv Oblast and showed lawmakers photographs from the scene, including one of the infant who was killed in a stroller.

“This is how Russia responds to the lifting of sanctions and the easing of pressure,” he said in the post.

Zelenskyy said Ukraine needs air defense and that no one should think about making money with Russia while it continues its war. He asked that sanctions on Russia stay in place until the killing stops, urged the US to “be strong” and apply Lindsey Graham’s law, and called on Europe to keep supporting Ukraine.

Ukrainian forces have liberated more territory since the beginning of the fall than Russian troops have captured during the same period. This trend has persisted throughout 2026, Ukrainian President Volodymyr Zelenskyy said in his 18 October address. He also reported that Dobropillia, Kostiantynivka, and five other settlements remain under Ukrainian control.

Russia systematically exaggerates its battlefield gains. A recent briefing by Valery Gerasimov, chief of the General Staff of the Russian Armed Forces, in which he claimed that Russian forces had captured 92 settlements since the beginning of September, as well as Kostiantynivka and Dobropillia, and advanced to within 5 kilometers of Zaporizhzhia, was based on “outright lies, manipulation, and exaggerations,” Ukrainian General Staff spokesperson Andrii Kovaliov said.

Ukraine also continues to defend areas near Kramatorsk, Zelenskyy said. He dismissed Russian claims about Zaporizhzhia.

“We are destroying Russians 20 kilometers from Zaporizhzhia, not five, as someone in Russia is fantasizing to Putin,” Zelenskyy said.

Ukrainian forces continue to hold back Russian assaults and destroy groups of occupying troops attempting to infiltrate Dobropillia, the president said. The Defense Forces are also defending positions elsewhere in Donetsk Oblast and in Kharkiv and Zaporizhzhia oblasts.

Zaporizhzhia axis: Russians seek to move artillery closer to the city

Russia seeks to advance on the Zaporizhzhia axis to bring the regional capital within range of its tube artillery, hold forward positions, and protect rear areas from Ukrainian strikes, the Institute for the Study of War (ISW) said on 18 October.

Maksym Kravchuk, spokesperson for Ukraine's Southern Group of Forces, refuted Gerasimov’s claims that Russian forces had captured Malokaterynivka, located south of Zaporizhzhia, stressing that the settlement remains under Ukrainian control, the Center for Countering Disinformation said on 18 October. Ukrainian troops recorded a video directly from Malokaterynivka to confirm this.

As of 18 October, Russian forces had advanced or infiltrated to within 24 kilometers of Zaporizhzhia, ISW said.

Dobropillia remains under Ukrainian control despite Russian assaults

Dobropillia is now a fortress anchoring Ukrainian positions along the highway leading northeast toward Kramatorsk. Russia first tried to take Dobropillia in August 2025 and is now trying again.

Russia is redeploying reinforcements to the Dobropillia axis and continues to send assault infantry through the village of Nove Shakhove despite heavy losses. Russian command will likely try to encircle or at least envelop Dobropillia and cut off Ukrainian supply routes from the direction of Bilozerske, Ukrainian military analyst Kostiantyn Mashovets wrote on 9 October.

Mashovets sees the push as the southern flank of a Russian effort to envelop the whole Sloviansk–Kramatorsk urban area.

Dobropillia remains under Ukrainian control, Zelenskyy said. On 18 October, footage located by analysts showed a Russian soldier hoisting a flag in the town's southeast after an infiltration, yet ISW has found no sign that Russian troops have dug in there.

Russia claimed to have captured Kostiantynivka, but ISW found no evidence

Ukrainian troops in and around Kostiantynivka are stopping Russia from locking in its gains in the city or pushing on toward Druzhkivka and Kramatorsk, ISW said on 17 October.

Russian officials claimed that capturing Kostiantynivka was an important step toward establishing control over the Sloviansk–Druzhkivka–Kramatorsk urban agglomeration and the entire Donetsk Oblast, ISW said in August. The Kremlin also claimed that Russian forces had captured the city as early as 5 July, the institute added.

A Russian military blogger claimed that Russian forces had full control over Kostiantynivka, but ISW found no evidence to support this claim, the institute said in its 16 October assessment. Russian troops had only infiltrated parts of southern and central Kostiantynivka without consolidating positions, and there was no evidence of their presence in its northern part, ISW added.
