In this year-end wrap-up of Ukraine This Week, the Kyiv Independent’s Anna Belokur looks back at the moments that defined 2025, the fourth year of Russia's full-scale invasion of Ukraine — from stalled peace efforts and escalating Russian attacks to mass anti-corruption protests and political upheaval at home.

The refinery was attacked multiple times in the night, residents claimed. An electrical substation in Syzran was also hit, causing blackouts in the city.

Ukrainian and Russian troops have been publishing conflicting claims and videos about who controls the front-line town of Myrnohrad, located just northeast of the embattled town of Pokrovsk.

A source close to the Ukrainian delegation told the Kyiv Independent that they don't know how the meeting will unfold and are ready for "all scenarios."

Without security guarantees, Ukraine cannot take any steps towards peace or hold presidential elections, which Trump's administration has pressured Zelensky to implement.

Several waves of explosions were heard across the capital, according to Kyiv Independent reporters on the ground, as well as in Kyiv Oblast, where power outages were reported in the town of Brovary and surrounding areas following the strikes.

Russia launched nearly 500 drones and 40 missiles overnight on Dec. 26-27, largely targeting Kyiv’s energy and civilian infrastructure.

Denis Kapustin, also known by his nom de guerre "White Rex," led the right-wing Russian Volunteer Corps until he was killed by an FPV drone on the southern front, according to preliminary reports. More details are expected later.
