Background: Ukraine previously warned that Russia could use Belarusian military infrastructure for an offensive at any time. On 5 June, Ukraine's State Border Guard Service reported that Russia has increased drone attacks launched via Belarusian territory, with most drones entering Belarusian airspace before crossing into Ukraine via Kyiv and Zhytomyr oblasts. Spokesperson Andrii Demchenko stated that Belarus has not condemned this practice, and that the Kremlin is actively pressuring Belarus to join the war with its own forces. Ukraine continues to strengthen northern defenses, though no significant Russian troop buildup near the border has been observed.

Ukraine's Commander-in-Chief Oleksandr Syrskyi reported that Russia has concentrated more than 140,000 troops across three hot sectors of the southern front: over 71,000 in the Oleksandrivka sector, with similar numbers in the Huliaipole and Orikhiv sectors. During a working trip to frontline units, Syrskyi discussed strengthening positions, supported commanders' initiatives for active operations, and ordered additional technical equipment and ammunition. He also met with Major Robert Brovdi, commander of the Unmanned Systems Forces, to discuss the development and use of unmanned systems, emphasizing the preservation of soldiers' lives as the top priority. Subsequently, Ukrainian military spokesperson Viktor Tregubov reported that the highest Russian activity is currently on the Lyman front, where Russian forces are attempting to advance toward the Sloviansk–Kramatorsk agglomeration but are being stopped by well-prepared Ukrainian defenses. The situation near Kupiansk is more complicated, with Russian forces concentrating drone units to strike Ukrainian logistics on the eastern bank of the Oskil River. Russian attempts to break through toward the town on the right bank via Holubivka failed. In Vovchansk, combat has intensified but remains stable. In the Velykyi Burluk area, Russian forces have shifted to defense after recent failures, now controlling only one settlement. Over the past day, 269 combat engagements were recorded.

Russia's slow advance in Donetsk Oblast continues, with forces stalled at Kostiantynivka for six months and territorial gains averaging only 2.63 km² per day in 2026. Now, Ukrainian forces are preparing for an expected Russian summer offensive targeting the Donbas strongholds of Chasiv Yar and Kostiantynivka, which guard the approach to the fortified cities of Sloviansk and Kramatorsk. Front-line conditions include the use of drone detection and FPV threats. The war has resulted in hundreds of thousands of casualties, and Russia remains determined to seize the entire Donbas territory.

A Ukrainian unmanned surface vessel (USV), disrupted by Russian electronic warfare during a combat mission in the Black Sea, drifted into Romanian territorial waters and detonated in the port of Constanța. No casualties were reported. Romanian President Klaus Iohannis convened an emergency security meeting at the 243rd Radioelectronic and Surveillance Brigade headquarters in Constanța with senior defense, intelligence, and border management officials to review the incident and assess options to enhance maritime surveillance, electronic tracking, and rapid-response capabilities. The prosecutor's office attached to the Constanța Court of Appeal opened a formal investigation. The incident follows a recent Russian drone crash into a residential building in Galați, highlighting ongoing border security challenges for NATO member Romania.

The Eastern Human Rights Group reports that Russia has recruited at least 88,000 residents of occupied Ukrainian territories into its military, based on the issuance of electronic 'SVOi' cards by Russia's PSB Bank. The cards grant combat veteran status and access to state benefits. The group says this is a deliberate strategy to integrate locals into the war effort and reduce the local population in favor of settlers loyal to Russia.

OSINT analysis suggests a strike may have hit the Research Institute of Marine Thermal Engineering in St. Petersburg, a key Russian facility developing torpedo systems for the Navy.

The appeal highlights Russia's systematic destruction of Ukrainian cultural heritage as part of its war effort.

Background: Ukraine has warned that Russia is increasingly integrating Belarus into its war effort by using its territory for drone operations and expanding military infrastructure near the border. Today, Franak Viacorka, adviser to Belarusian opposition leader Sviatlana Tsikhanouskaya, outlined the democratic opposition's strategy to split the Belarusian nomenklatura by leveraging secret support from ministers and regional officials who hate Lukashenko. He elaborated that several ministers and deputy ministers secretly supported Tsikhanouskaya in 2020 and many remain in their positions, and that regular officers, police, and mid-level regional officials hate Lukashenko and could become allies. Viacorka assessed that a pro-Russian clique around Lukashenko has concentrated power but is small in number, while a large swath of officials is pro-independence and pro-European. He warned that US engagement with Lukashenko risks legitimizing the regime and freezing the situation under Russian control, and urged maximum sanctions until democratic change occurs. Viacorka also confirmed that Russia is modernizing Soviet infrastructure and building military bases along all Belarusian borders except Russia's, and deploying Oreshnik missiles and nuclear weapons as blackmail, though he assessed no immediate invasion due to insufficient Russian manpower.

Ukrainian forces destroyed a Russian VMM-3M bridge-laying vehicle on the Vovchansk front as it attempted to establish a river crossing.
