Russia fired at least 5,134 drones in overnight attacks in the final month of 2025, six percent less than the month before, while the number of missiles fell by 18 percent in the same period, according to the data.

However, the same data showed Ukraine destroyed a smaller share of the total sum of missiles and drones in December -- 80 percent, compared with 82 percent in November.

Ukraine came under intense pressure in 2025, both from Russian bombardment and on the battlefield, where it has steadily ceded ground to the Russian army.

Moscow -- which denies targeting civilians -- has fired drones at Ukraine every single night since May 10, when a unilateral three-day truce announced by President Vladimir Putin to coincide with a grand military parade in Moscow ended.

US President Donald Trump, who regularly complains he does not receive credit as a peacemaker, has engaged in talks with both sides in a bid to end the fighting.

But he has so far failed to extract major concessions from the Kremlin -- which currently occupies around a fifth of Ukraine.

Kyiv says Russia is not interested in peace and is deliberately trying to sabotage diplomatic efforts aimed at ending the war to seize more Ukrainian territory.
