**Deck**: Ukrainian reports say Russia launched a record 600 drones in 24 hours and probed Romanian airspace, with low clouds hiding gasoline-powered aircraft from defenses as Kyiv sat in darkness and another refinery burned.

Russian drone and bomb attacks are pushing Ukraine’s air defenses and power grid into a new phase of strain, according to Ukrainian accounts that describe record volumes of strikes and long blackouts in the capital.

One battlefield summary says Russia launched 600 drones in a single 24‑hour period, the highest daily figure reported so far. The drones were described as older gasoline‑powered models that became difficult for Ukrainian air defenses to spot under low cloud cover. Ukrainian reporting also claims Russia has stockpiled around 15,000 of these drones since May.

The same account says some drones probed Romanian airspace, bringing the campaign close to NATO territory, and that Kyiv remained without power for more than 15 hours. Ukrainian sources add that a third refinery was burning in three nights, pointing to sustained attacks on energy infrastructure. These details have not been independently verified.

Separately, President Volodymyr Zelensky said that over the past week Russia fired 1,940 attack drones, more than 1,580 guided air‑dropped bombs and 44 missiles of various types at Ukraine, including 36 ballistic missiles.

Ukrainian commentary linked the latest refinery fires to what it called the death of an "energy deal" despite a recently announced $2.1 billion U.S. Patriot air‑defense package. In that framing, Russian strikes are outpacing new Western support and forcing Kyiv to look for other ways to pressure Moscow.

Those same reports say Ukraine’s leadership is now placing more emphasis on the Black Sea, with Zelensky seeking support for actions that would target Russian logistics and energy interests there rather than relying only on shooting down incoming weapons.

Together, the claimed 600‑drone day, the weekly totals cited by Zelensky and the repeated refinery fires suggest a Russian strategy built around large numbers of relatively cheap systems, aided at times by weather that blunts Ukraine’s defenses. How NATO responds to reports of drones nearing Romanian skies, how much of Ukraine’s energy network remains functional as winter approaches, and whether Kyiv can gain new leverage at sea will shape whether this pattern stabilizes or escalates further.
