Ukraine’s forces launched a massive drone attack on four airfields deep inside Russia that were home to strategic bombers used in air raids, officials said on Sunday, in possibly their most audacious attack of the war.
“At this point, more than 40 aircraft have reportedly been hit,” an official told the Financial Times, adding that drones struck four Russian military airfields in “one co-ordinated operation” thousands of kilometres away from the front line.
Aircraft were “burning” at the Belaya airfield, located near Sredny in south-eastern Siberia about 5,500km east of the Ukrainian border; at the Olenya air base on the Kola Peninsula near Murmansk; Dyagilevo air base 200km south-east of Moscow; and Ivanovo airfield, 300km north-east of the Russian capital, the official said.
Video footage filmed by a Ukrainian reconnaissance aircraft and shared by the official appeared to show one Russian airfield in flames and drones attacking several planes. In another video, the voice of Vasyl Malyuk, the head of the Security Service of Ukraine (SBU), is heard approving the attacks.
The massive co-ordinated attack by the SBU came as the country’s President Volodymyr Zelenskyy said he would dispatch a team of negotiators to Istanbul for another round of peace talks.
According to people familiar with the operation, the drone attack, codenamed Spiderweb, was planned more than a year in advance and “personally supervised” by Zelenskyy. It used dozens of small “first-person view” drones armed with explosives.
The SBU smuggled the drones into Russia, followed later by small wooden mobile cabins, the people said. The drones were concealed under the roofs of the structures, which had been loaded on to lorries. On Sunday, the roofs were remotely opened and the drones launched towards Russian military airfields.
“This is exactly what we need to win the war, which is an asymmetric conflict — military creativity like that,” said Oleksandr Merezhko, head of the Ukrainian parliament’s foreign affairs committee.
A former Ukrainian officer who runs analytical group Frontelligence Insight said that while the damage would probably not directly influence Russia’s position on the battlefield, it was still significant.
“It does reduce Russia’s strategic capabilities [which] mean the ability to project power globally, the ability to deliver nuclear strikes and overall military posture in Eurasia,” he said. “When [the Russian] general staff plans wars, they don’t look just at one theatre of war or specific part of the front line. They assess the military capabilities and project how to execute the political will of leadership.”
Ukraine’s attack would dent Russia’s “geopolitical confidence”, he added.
The SBU estimated that the attack caused more than $7bn worth of damage and claimed that 34 per cent of Russia’s strategic cruise missile carriers were hit.
Russia’s defence ministry confirmed the Ukrainian drone attacks on the air bases and said that several aircraft had caught fire, according to statements carried by Russian state media.
The ministry claimed it had detained an undisclosed number of “participants in the terrorist attacks”. The SBU earlier said that all those involved in the operation had left Russia long before the attacks.
In recent days, Zelenskyy has blasted Putin for failing to provide a “memorandum” outlining Russia’s conditions for peace. The memo had been promised to Kyiv and Washington ahead of the next round of negotiations.
A senior Ukrainian official said Kyiv expects Moscow to present “extreme demands” that it could not agree to because, if implemented, it would mean the end of Ukraine as a sovereign nation.
Ukraine’s negotiators will present a draft peace proposal to their Russian counterparts on Monday. It lays out what Kyiv sees as a viable path to the end of the war.
The proposal, seen by the Financial Times on Sunday, calls for a full and unconditional ceasefire in the sky, on land and at sea — to be monitored by the US — followed by the release of all prisoners, the return of Ukrainian children forcibly taken to Russia and an agreement for Zelenskyy to meet Putin.
“The key issues can only be resolved by the leaders,” Zelenskyy said earlier on Sunday.
The Ukrainian document calls for security guarantees to ensure Russia will not invade again. It says there must be no formal international recognition of Russian sovereignty over Ukrainian territories currently under Moscow’s control. The front line “is the starting point for negotiations,” it stated. “Territory issues are discussed only after a full and unconditional ceasefire.”
There must be no restrictions on Ukraine’s military strength and western sanctions on Russia should be lifted gradually but with a mechanism to reapply them if Moscow breaks the agreement, the document said. Frozen Russian sovereign assets are to be used “for reconstruction or remain frozen until reparations are paid”, it added.
Zelenskyy said Ukraine’s delegation would again be led by defence minister Rustem Umerov and that Russia had received his terms already.
Moscow’s delegation will be led by Vladimir Medinsky, who led failed talks with Ukraine during the early months of Russia’s full-scale invasion in 2022 as well as the most recent meeting in Istanbul last month. Igor Kostyukov, head of Russia’s military intelligence agency, deputy foreign minister Mikhail Galuzin and deputy defence minister Alexander Fomin will also join the talks alongside a ground of Russian experts.
Moscow on Sunday launched 472 drones over Ukraine overnight in its largest drone attack since 2022, according to Ukraine’s air force. Explosions were reported in the cities of Kharkiv and Zaporizhzhia, while air defences were activated over Kyiv.
Russian forces also launched three ballistic missiles and four cruise missiles, according to the Ukrainian air force, which said strikes had been recorded in 18 locations. Three cruise missiles and 382 drones were either shot down or jammed with electronic warfare devices.
One missile strike on a military training ground in the country’s east killed 12 people and injured more than 60. Ukrainian ground forces did not disclose the location of the strike or the missile used. Its top commander Mykhailo Drapatyi offered his resignation over the attack.
“Circular responsibility and impunity are poison for the army. I tried to eradicate them from the ground forces,” he said in a statement. “But if tragedies are repeated, then my efforts were not enough.”
Russian ground forces have stepped up their latest offensive in the Ukrainian region of Sumy, where they control at least 110 square kilometres of territory, according to DeepState, a war-monitoring group linked to the Ukrainian military.
Zelenskyy told reporters earlier this week that Moscow had gathered more than 50,000 troops in the area for a possible offensive towards the regional capital. Ukrainian authorities ordered the mandatory evacuation of 11 villages in the area.
