Key Takeaways from the ISW:

• Russian forces continue to struggle to defend Russian infrastructure against repeated Ukrainian strikes.
• Russian forces attempted to use long-range one-way strike drones to assassinate Serhiy “Flash” Beskrestnov, a Ukrainian Ministry of Defense (MoD) advisor on defense technology and a drone and electronic warfare (EW) expert.
• Ukraine continues to expand its cooperation with Gulf States.
• Ukrainian forces recently advanced in the Borova direction and western Zaporizhia Oblast. Russian forces recently advanced in northern Sumy Oblast and in the Kostyantynivka-Druzhkivka and Dobropillya tactical areas.
