Russian and Ukrainian forces continued limited offensive operations on the final day of the May 9-11 ceasefire, accusing the other side of violating it.
This is according to the "Institute for the Study of War" (ISW).
The head of the Ukrainian Counter-Disinformation Center, Lieutenant Andriy Kovalenko, reported that Russian forces did not carry out long-range strikes against Ukraine on the night of May 10-11.
Observed data signatures from NASA's Resource Management System on May 11 show that hostilities continued to decline on May 11, but did not cease. A spokesman for a Ukrainian brigade operating in the Lyman direction reported that Russian forces had used the ceasefire to withdraw reserves, build up personnel, and continue artillery and first-person strikes.
The spokesman reported that Russian forces had increased Molniya drone strikes during the ceasefire compared to before the ceasefire, and suggested that Russian forces may have stockpiled Molniya drones. before the ceasefire for this purpose.
A ceasefire without clear implementation mechanisms, reliable monitoring, and defined dispute resolution processes is unlikely to hold.
Recent reports of Ukrainian drones operating near occupied Mariupol as part of an aerial cross-border effort targeting Russian ground communication lines in the occupied Donetsk region and Crimea have raised serious concerns among Russian bloggers. Russian bloggers expressed concern on May 10 in response to recent Ukrainian footage of Ukrainian Hornet drones operating freely over the T-0509 Mariupol-Donetsk city highway (also called the H-10 highway) near occupied Mariupol, targeting Russian tanks and other military transport vehicles.
One of the bloggers expressed serious concern that the situation near Mariupol is beginning to resemble the conditions on the M-30 Gorlovka-Panteleymonovka-Yasinova-Donetsk city highway, where, according to the blogger, Ukrainian forces have paralyzed Russian logistics and civilian traffic using drones.
The blogger claims that the M-30 highway was safer in 2024-2025, despite being closer to the front line, compared to 2026, when the M-30 was 35 kilometers from the front line, due to the increased range of Ukrainian drones. The blogger claims that Russian electronic warfare can only jam Ukrainian Hornet drones if they are not using Starlink or do not have time to automatically target the target. The blogger expressed concern that Ukrainian forces may be able to fully automate Hornet drones in the next six to 12 months (around December 2026 to March 2027).
Another blogger echoed these concerns, expressing concern that Ukrainian Starlink-powered drones with a range of up to 200 kilometers are reaching the M-14 Mariupol-Berdyansk-Melitopol-Genichesk highway, a key Russian air transport hub along the Azov Sea coast to occupied Crimea.
