The Russian strikes are inflicting “unimaginable levels of suffering” on Ukrainian civilians, according to Ramesh Rajasingham, coordination director in the UN humanitarian office.
Andriy Yermak, the president’s chief of staff, said Russia had expanded the number of drones it uses in its routine nighttime attacks as winter approaches.
“The battle for the sky is what awaits us,” he said on Telegram.
Laser-guided munitions designed to take out drones are expected to be part of a US$425 million ($709m) package of new US military aid to Ukraine, according to US officials.
The coming wet, muddy and cold weather will likely frustrate both sides’ efforts to advance on the battlefield, compelling a change in military tempo.
Russia and Ukraine will be building up ammunition stockpiles for offensives in 2024, analysts say. Ukraine is relying heavily on its Western allies and plans to ramp up its own weapons manufacturing while Russia buys from North Korea, Iran and Belarus.
Both armies are struggling to make major progress along the 1500-kilometre front line in what is largely an artillery war. Ukraine’s commander-in-chief, General Valerii Zaluzhnyi, said in published remarks this week that artillery, missile and rocket fire account for up to 80 per cent of all military tasks.
Ukraine’s forces can now wear down Russian logistics and command centres behind the front line using US long-range ballistic missiles, known as ATACMS, and UK long-range Storm Shadow cruise missiles.
The planned delivery of F-16 fighter jets to Ukraine in the first part of next year will also improve Kyiv’s military might. Its months-long counteroffensive to push back Russian troops has taken place without air cover.
