Ukraine launched one of its largest drone attacks on Moscow overnight, sending more than 400 drones toward the Russian capital, according to Russian officials, as the war between the two countries continued to escalate.

Moscow Mayor Sergei Sobyanin said the drones were launched from late Sunday into early Monday, with Russian air defenses intercepting the majority before they reached the capital.

Sobyanin said 85 drones were shot down in the vicinity of Moscow, while many others were intercepted farther away from the city.

The barrage came just hours after Russia launched fresh ballistic missile strikes against Kyiv and other Ukrainian cities, extending a cycle of retaliatory attacks that has further diminished hopes for a negotiated end to the more than four-year war.

Officials in the Moscow region said the drone assault caused injuries and damage to civilian property.

Andrei Vorobyov, governor of the Moscow region, said 10 people were wounded, while several residential buildings and infrastructure facilities sustained damage.

Meanwhile, Ukrainian President Volodymyr Zelenskyy said he would hold a series of “key talks” on Monday as he seeks to contain a growing political crisis at home.

The tensions follow last week’s government reshuffle, which exposed divisions within Ukraine’s leadership over the country’s military strategy.

The replacement of reform-minded Defense Minister Mykhailo Fedorov and President Zelenskyy’s decision to retain Armed Forces Commander Gen. Oleksandr Syrskyi have sparked criticism from some Ukrainians.

The changes have fueled several days of demonstrations supporting Fedorov and opposing Syrskyi, highlighting growing public debate over the direction of Ukraine’s war effort.

Zelenskyy is expected to use Monday’s meetings to reassure both the public and political allies that the leadership changes will not weaken Ukraine’s military campaign against Russia.

Separately, Ukrainian forces reportedly struck another Russian oil depot, continuing Kyiv’s strategy of targeting energy and logistics infrastructure to disrupt Moscow’s military operations.

The latest developments underscore both the intensifying battlefield conflict and the mounting political pressures facing Ukraine’s leadership as the war enters its fifth year.
