Montenegro has ordered the expulsion of Mikhail Zvynchuk, head of the pro-Kremlin military information network Rybar, and four other Russian citizens over national security concerns following a security operation targeting suspected Russian hybrid influence activities, Vijesti reported on 9 October.

Zvynchuk is the founder and head of Rybar, a prominent Russian military-focused information network known for its Telegram channels covering Russia's war against Ukraine. The network promotes pro-Kremlin narratives and has been associated with Russian propaganda and influence operations.

Montenegrin police announced on 9 October that the five Russians had their residence rights revoked and were ordered to leave the country on national and internal security grounds. 

Montenegro investigates suspected Russian hybrid activity

The operation involved Montenegro's police and National Security Agency (ANB), which seized drones, high-resolution recording equipment, cameras, and several mobile phones for further examination, according to Vijesti.

According to Montenegrin authorities, the five had arrived in the country less than two days before the operation. The investigation is being conducted with support from international partners.

Montenegrin police identified the five Russian citizens as Zvynchuk, his wife Valeria Zvynchuk, Sergei Belous, Pavel Lekatorchuk, and Kira Doroshenko. Authorities said the case had been referred to prosecutors in Podgorica and Kotor.

The European Union has sanctioned Zvynchuk over activities that undermine or threaten Ukraine's territorial integrity, sovereignty, and independence. He has also been sanctioned by the United Kingdom, Switzerland, Australia, and Ukraine, according to Vijesti.

Suspected influence operation targeting EU integration

Vijesti reported, citing security sources, that Montenegrin authorities suspected the group of planning a documentary intended to undermine public support for the country's European integration.

According to the outlet, the planned material would portray Montenegro's expected alignment of its visa policy with EU standards as a politically imposed measure that threatens tourism, economic stability, and national interests.

Security services had monitored the group's arrival before carrying out the operation in Risan, in the Bay of Kotor area, Vijesti reported. The equipment seized from the group will undergo expert analysis to establish its intended purpose and use in Montenegro.

Medvedev threatens imprisoning “European and American idiots” for prisoner exchanges

Former Russian President Dmitry Medvedev responded to the operation by suggesting Moscow might need to expand its pool of prisoners to exchange for Europeans and Americans to secure Zvynchuk's return.

“We will probably have to replenish our pool of prisoners for exchange with European and American idiots,” Medvedev said, according to Vijesti.

Montenegro, a NATO member and EU candidate, has aligned itself with EU sanctions against Russia following Moscow's full-scale invasion of Ukraine in 2022. The expulsion comes amid broader European concerns over Russian intelligence activity, propaganda, and other forms of hybrid interference. 

A Ukrainian company has played the enemy in a Pentagon drone contest, and the US liked what it saw. Phantom Defense, a Ukrainian defense-tech firm, was one of three companies whose systems built the counter-drone environment for Gauntlet II, the second stage of the US military’s Drone Dominance program, and has been invited to take part further, Defender Media reports.

Drone Dominance is the Pentagon’s four-phase effort to field cheap attack drones fast, a roughly $1 billion program to buy more than 200,000 low-cost attack drones by 2027. Phantom Defense brought a system that was already proven at home, where in one city it neutralized more than 7,000 enemy drones over an area of more than 100 square kilometers in a year, the company says.

Rather than enter a drone of its own, Phantom Defense supplied the resistance that the American drones had to fly through. Its setup paired the Specter PRO, L, X, and XL jammers with the Streamhunter video-interception tool and a command-and-control layer that detected and classified targets, coordinated the countermeasures, and confirmed the kills. The jammers suppressed drones and held up in heat and rain, it adds.

The arrangement lets American developers fly their drones under live electronic attack rather than calm conditions, recreating a battlefield where a drone’s performance swings with the jamming around it, according to the company.

One map to run the whole fight

At the center sits Phantom Defense’s C2 system, Kupol, which integrates separate tools into a single ecosystem on a shared map. It lets crews run electronic warfare remotely, without driving out to a position, and ties in sensors, interceptor drones, and turrets, the company says.

Kupol reads the terrain and a drone database to propose the best way to take down a target, then logs each mission automatically so its recommendations sharpen over time.

The high-power Specter PRO station, built to shield positions, critical infrastructure, and cities, serves as the hardware anchor.

An invitation, not yet a contract

Previously, Ukraine’s battle-tested drone makers also took part in Drone Dominance. However, they didn’t succeed in it, though some of their technology competed under Western partners. The program bars direct purchases from Ukrainian firms, which must set up a US legal entity to bid.

Ukrainian forces are advancing east of Sloviansk and Kramatorsk, and even Russian milbloggers now acknowledge it, the Institute for the Study of War (ISW) said on 8 October. The gains may follow months of groundwork like the one that preceded Operation Vivaldi near Lyman, which Ukraine says returned 176 km² to its control. Russian commentators are already doubting that Moscow can reach the two cities.

Russia's years-long push on the Fortress Belt, the chain of cities anchoring Ukraine's defense in Donetsk Oblast, has been stalling since Vivaldi began. Unable to take those cities, Russia keeps hitting them from the air. On 8 October, a Russian bomb killed 30 people on two buses in Kramatorsk.

Across the Siverskyi Donets

Russian milbloggers said Ukrainian forces liberated Ozerne and advanced east of Pyskunivka toward Kryva Luka, ISW reported. They also acknowledged that Ukrainian troops drove Russian forces out of Pyskunivka. Ukrainians are now counterattacking toward Kryva Luka from the west and northwest, from across the river.

ISW called the repeated Russian claims of a river crossing notable, because the Siverskyi Donets is a significant natural obstacle. Kryva Luka is a dominant height just south of the river. From there, Ukraine could launch further counterattacks. Ukrainian forces appear to have pushed Russian troops off both banks in this area, ISW assessed.

The heights Russia wanted

After Vivaldi cleared ground near Lyman in September, Russia shifted its push south toward Mykolaivka and Sloviansk. Russian forces likely see Mykolaivka, just east of Sloviansk, as a primary objective, ISW said. Its heights would favor an offensive on the city. Ukrainian pushes northeast and southeast of the town now deny Russia that terrain.

East of Kramatorsk, milbloggers claimed Ukrainians liberated Malynivka and advanced between Fedorivka Druha and Holubivka. They also reported gains into southern Minkivka and near Fedorivka. The lines remain tangled. Geolocated footage shows Ukrainian forces striking a Russian position in central Tykhonivka after what ISW assesses was a Russian infiltration.

ISW said the counterattacks may point to a broader Ukrainian goal: pushing Russian forces east, away from the Sloviansk–Kramatorsk area and toward the Siverskyi Donets–Donbas Canal.

The Vivaldi playbook

The counterattacks have run for weeks. On 29 September, Ukrainian military observer Kostiantyn Mashovets reported them in the same areas, saying Russia's 3rd Combined Arms Army had failed to make significant gains. ISW assesses that the attacks build on months of shaping meant to wear down Russia's offensive capacity.

Before Vivaldi, Ukrainian forces targeted Russian drone operators, gaining drone superiority before the counteroffensive. They used the same approach ahead of their Oleksandrivka counterattacks in early 2026.

Moscow appears to see the pattern. A Ukrainian military official said on 7 October that Russia is moving drone units and Spetsnaz from quieter sectors to the Sloviansk–Kramatorsk direction. Ukraine also reorganized its command in and around Donetsk Oblast in early September, which may be blunting Russian attacks from the east, ISW said.

"Distant" and "doomed"

One Russian milblogger called an advance toward the Sloviansk–Kramatorsk area a "distant" prospect, ISW reported. A Russian offensive from Siversk toward Sloviansk may be "doomed" to failure or heavy losses unless Russia retakes the forests south of Lyman, he said.

The counterattacks east of the two cities appear to support Vivaldi, ISW assessed. Together with Russia's defeat north of the river, they could disrupt Russia's offensive toward Sloviansk from the east entirely.

If Ukraine holds Kryva Luka and keeps Russia off the Mykolaivka heights, Moscow's pincer on Sloviansk and Kramatorsk loses the ground it was built on.
