Frontline Situation Update
Russian servicemen have published flag-raising videos filmed in the village of Rai-Oleksandrivka, southeast of the city of Sloviansk. This sector of the front has seen relatively little movement in recent months. During the winter and early spring, the Russian Armed Forces advanced steadily in the area following the capture of the town of Siversk, but the pace of the offensive later slowed considerably, apparently after Russian forces reached prepared Ukrainian defensive positions. Despite Russian claims that the videos confirm the capture of Rai-Oleksandrivka, we believe they are more indicative of continued infiltration than of successful consolidation of control over the village. Topographic maps show that Russian forces approached Rai-Oleksandrivka through low-lying terrain from the direction of the villages of Riznykivka and Kalenyky. Any further advance toward Sloviansk would require them to push uphill against Ukrainian defensive positions established on elevated ground, a considerably more difficult task than their earlier movement through the lowlands.
Russian forces also continue their infiltration tactics in the Lyman direction. Videos showing Russian flags inside the town of Lyman have recently appeared, and the analyst Playfra appears to share a similar assessment of the situation. As noted earlier, the objective of these advances is to reach the Siverskyi Donets River, which would allow UAV operators to disrupt Ukrainian logistics in Sloviansk and Mykolaivka. At present, however, the riverbank remains captured by Ukrainian drone teams, which are targeting Russian assault troops attempting to push toward Sloviansk from the east. Similarly, earlier Russian advances around the town of Yampil appear to have facilitated subsequent operations farther south, in the areas around Riznykivka and Kalenyky.
Ukrainian troops reported repelling a mechanized assault launched on June 12 in several waves toward the village of Kryva Luka, east of Mykolaivka. According to the Ukrainian military, the attack involved a total of 28 motorcycles, one tank, three infantry fighting vehicles and seven other vehicles. The assault was reportedly thwarted after Ukrainian drones detected the approaching force in time to direct strikes against it. Meanwhile, Russia's developing fuel shortage does not yet appear to be limiting its ability to deploy motorcycles and vehicles in assault operations.
The situation for the Armed Forces of Ukraine in the town of Kostiantynivka continues to deteriorate. In recent days, videos have emerged showing Russian assault troops operating in the town center and in areas just to its north. Analysts from DeepState have described these developments as the realization of a worst-case scenario, drawing parallels with the town of Pokrovsk. There, Russian assault groups spent months infiltrating the town, building up their presence, gradually severing Ukrainian supply routes and methodically taking control of one neighborhood after another. Given the size of Kostiantynivka, the fighting could still continue for a considerable period of time.
We have no new information regarding Ukrainian counterattacks.
Ukrainian and Russian Strikes
Ukrainian drone strikes against crossings in occupied Crimea and routes linking the peninsula with the occupied part of the Kherson region continue. Footage has emerged showing a strike on the railway bridge across the North Crimean Canal near the village of Rozdolne in the northeastern part of Crimea. This railway line provides a route from Russia through southern Crimea into the Kherson region. We do not believe this will significantly worsen the fuel situation. It is worth noting that the Crimean Bridge is generally not used for fuel transportation, while ferry crossings, to the best of our knowledge, are not currently operating.
According to the latest statement by Vladimir Saldo, the Russian-appointed governor of the occupied part of the Kherson region, the border-crossing points at Dzhankoi and Armyansk remain operational, although the former is open only during daytime hours. The Chonhar bridge is closed, and work appears to be underway to establish a pontoon crossing. The bridge near the village of Myrne is operating normally, though a backup route is being prepared in case it becomes necessary. Meanwhile, the bridge between the villages of Stavky and Preobrazhenka in the Kherson region has been closed, with traffic redirected via an “alternative canal crossing.” In the Arabat Spit area, a pontoon crossing is operating across the Promoyina Strait, while work is ongoing in the Tonkyi Strait. Thus, although regular strikes temporarily disable bridges and crossings, the pro-Russian authorities are attempting to restore access quickly and construct approach roads to pontoon crossings in order to mitigate the effects of future strikes. As a result, they have so far been unable to completely sever Crimea’s logistical links with mainland Ukraine.
On the morning of June 17, a UAV struck a bus near the village of Rudnya in the Pochepsky district of Russia’s Bryansk region. The bus was travelling from Gomel in Belarus toward Bryansk and, according to acting governor Yegor Kovalchuk, was carrying children to Gelendzhik in the Krasnodar region. As a result of the strike, a woman accompanying the group was killed, while seven other people, including five children, were injured. Since the strike location is approximately 50 km [31 mi] from Ukrainian territory, it is unlikely that a tactical FPV drone was used. More likely, the attack was carried out by a medium-range strike drone not equipped with a large warhead. We do not know why this particular bus became the target. A misidentification error—either by an operator or by machine-vision systems—cannot be ruled out.
We remain highly skeptical of claims that this was a false flag attack carried out by Russian intelligence services in order to pressure Belarus into entering the war. The Security Service of Ukraine (SBU) published what it claims is an intercepted report from Russian soldiers stating that no UAV flights were detected in the Pochepsky district at the relevant time. However, this document does not refute the possibility of a Ukrainian UAV strike. The ground surveillance radars located near Bryansk in the village of Suponevo would be unable to detect low-flying drones at such a distance (Rudnya is more than 90 km [56 mi] away), while visual detection is highly unreliable.
On June 18, the 413th Regiment of the Ukrainian Unmanned Systems Forces published a video of a strike on a locomotive near the village of Zhudilovo in the Bryansk region (more than 55 km [34 mi] from the border), which was hauling a fuel train.
In the early hours of June 18, drones struck an oil depot in Gukovo, Rostov region. According to local authorities, a guard was killed and two employees of a freight railway station were injured.
On June 18, Ukraine launched a massive drone attack on Moscow and the Moscow region. As a result, a large-scale fire broke out at an oil refinery in Kapotnya, while some drones also struck residential buildings. Governor Andrey Vorobyov stated that 17 people were injured in the Moscow region, including two children. On June 19, the UAV raid resumed, and according to Vorobyov, an 8-year-old girl died in a fire.
This was one of the largest UAV raids on Moscow, but we cannot verify whether it was indeed a record, as claimed by the Russian Ministry of Defense, which reported that 992 UAVs had been shot down. It is also impossible to calculate the number of drones heading specifically toward Moscow, since many of them were downed in regions near the Russia-Ukraine border. At the same time, Moscow Mayor Sergey Sobyanin stated on the morning of June 18 that about 200 drones had been shot down while approaching the capital. The following types of strike UAVs were reportedly used during the attack: FP-1, Antonov An-196 Liutyi, RZ-100 Morok, Behemoth and Sichen, resembling Shahed-type loitering munitions, as well as BARS cruise missiles.
A fuel storage tank at the Moscow Oil Refinery exploded after being struck, with its roof blown upward, producing highly dramatic footage. Several videos from different angles show a missile launched from the ground (either from a Pantsir-S1 surface-to-air missile and anti-aircraft artillery system or a MANPADS used to repel the raid) heading toward the tank shortly before the explosion. Based on this, many observers concluded that the tank had been detonated by that missile.
We are not entirely convinced by this interpretation, as during such large-scale attacks it is often difficult to determine which particular weapon caused the damage. In this case, numerous smoke plumes obscure the view, while surrounding buildings distort the sound. Multiple drones were airborne simultaneously, and missile conversion trails are also visible in the footage. In addition to a missile that may have missed a drone, the tank could have been struck by another UAV or even by debris from a drone intercepted by a different surface-to-air missile.
The possibility of such coincidences is illustrated by a video showing a person firing a pistol at an incoming drone, after which the drone explodes. In reality, the UAV was too far away to be brought down by those shots.
Several videos were also published showing anti-aircraft missiles passing by drones. In some cases, we believe these were not misses but rather missiles aimed at different targets. Another video shows a pair of drones approaching the refinery together. One crashes into a storage tank and explodes, while the other becomes entangled in a protective net and detonates some distance above the tank. This footage supports our argument that anti-drone nets can, in some cases, reduce the damage caused by an impact.
When Pantsir-S1 SAM systems engage an aerial attack, the separating missile's booster stage occasionally hits residential buildings or even civilians. This two-stage missile structure developed historically, as the Tula Instrument Design Bureau based its 1990s design on the missiles used for the 2K22 Tunguska SPAAG and SAM system. Furthermore, these air defense systems were not originally intended to be used in densely populated urban areas. Nevertheless, according to our sources, there were relatively few incidents during the recent attack on Moscow and the surrounding region, despite the highly active deployment of Pantsir-S1 SAM systems. This may be due to the introduction a year or two ago of new surface-to-air missiles for this system, which feature a non-separable engine, smaller dimensions and a lower cost—specifically engineered for intercepting drones.
In early June, a Ukrainian channel published an analysis suggesting that it is easier for aircraft pilots to shoot down jet powered drones than conventional propeller-driven ones. Fighter jets are designed for high-speed aerial combat, whereas countering standard UAVs forces pilots to sharply reduce speed and execute additional maneuvers to maintain a lock on the target. Furthermore, the homing heads of air-to-air missiles are designed to lock onto the nozzles and exhaust of jet engines, which heat up to very high temperatures, while the piston engines of Shahed drones do not emit the same amount of heat. Additionally, jet powered UAVs fly much faster and do not make sharp maneuvers, as their turning radius is much larger at higher speeds.
In one video recording showing attempts to shoot down drones using MANPADS a missile can be seen abruptly veering off course and flying in another direction. The operator was likely targeting a conventional drone, but after the launch, the missile detected a hotter jet powered UAV and locked onto it.
Dnipro OSINT counted five drone strikes on the Moscow oil refinery, while also noting one hit during a previous raid and one storage tank that, as discussed above, could have exploded from being hit by an anti-aircraft missile rather than a UAV. Even if several other hits are not displayed on the map, and even if the MoD exaggerated the number of intercepted targets in its aforementioned statement, many hundreds of drones were almost certainly launched at Moscow, and the effectiveness of the air defenses exceeded 95 percent—a high figure. Nevertheless, following an interception, some drones fall and detonate on the ground, causing additional damage to civilian infrastructure, while other UAVs strike the upper floors of residential buildings or construction cranes.
On the morning of June 19, an 8-year-old girl was killed and three other people were injured as a result of a Russian UAV strike on Pavlohrad in the Dnipropetrovsk region. The private house hit by the strike was destroyed.
On June 17, a driver was killed when a drone struck a civilian truck in Belgorod.
We assume that with the increase in the number of drones and missiles launched by both sides, the number of such strikes on non-military targets will continue to grow. As the scale of strikes expands, the quality of intelligence will inevitably decline. Generals will demand a broader geography of strikes, but it is obvious that maintaining a corresponding pace of replenishing the bank of legitimate targets is impossible, as the resources of any intelligence service are limited. All targets must be carefully verified: whether they are indeed weapons depots or military equipment, whether military movements have actually been recorded, and so on. Previously, we mostly observed Russia terrorizing Ukrainian civilians. Now, as Ukraine has caught up with Russia in the number of drones launched, we are seeing an increasing number of Ukrainian strikes on insufficiently reconnoitered targets, such as the strike on the pedagogical college in Starobilsk in the Luhansk region or the strike on the bus carrying children in the Bryansk region described above.
According to Politico sources, Donald Trump supported a tough G7 declaration on Ukraine after Volodymyr Zelenskyy showed him photos of the burning Dormition Cathedral. According to three G7 officials, the US president was visibly shaken. The effectiveness of such a move meets our expectations.
The G7 countries plan to tighten sanctions against Russia's oil and gas sector. The statement notes that now is a favorable moment for doing so, as the US and Iran have concluded an agreement on opening the Strait of Hormuz. Trump agreed to support Ukraine in the war with Russia in exchange for European assistance in the mine-clearing of the strait.
Czech military commentator Praisethesteph reported that the Czech Republic intends to supply Ukraine with more than ten Aero L-39 Skyfox aircraft, each specially adapted for intercepting and destroying drones. The aircraft can be equipped with two FN Herstal HMP-250 gun pods armed with 12.7mm machine guns, two seven-round LAU-32 launchers for 70mm FZ275 LGR/RR or APKWS II guided rockets, and a Phoenix electro-optical pod produced by SiNAB Technologies. Aero Vodochody's proposal to manufacture these aircraft for Ukraine had already been reported in January 2026.
