Russia’s largest airstrike hits Ukraine

Russia on Sunday launched its biggest aerial assault yet on Ukraine, killing four people and setting parts of Kyiv’s government district on fire.

President Volodymyr Zelensky, in his evening address, said the strikes would only prolong the war, warning that Vladimir Putin was “testing the world.” He called for a “strong response from America,” hours after U.S. President Donald Trump hinted at fresh sanctions on Moscow.

The Ukrainian Air Force said Russia fired at least 810 drones and 13 missiles overnight — the heaviest barrage since the war began more than three years ago.

For the first time, the sprawling government complex housing Ukraine’s cabinet of ministers was hit. Drone strikes also tore through residential blocks, wounding more than two dozen people, including a 24-year-old pregnant woman who delivered a premature baby shortly after the blasts. Doctors are battling to save them both.

In his reaction, French President Emmanuel Macron condemned Russia for “locking itself into war and terror,” while UK Prime Minister Keir Starmer called the strikes “cowardly.” EU chief Ursula von der Leyen accused the Kremlin of “mocking diplomacy.”

Putin’s government, however, denied hitting civilian sites, claiming only a plant and logistics hub were targeted.

Meanwhile, reports say European leaders are considering deploying troops to enforce a possible peace deal — a move Moscow has already warned would make Western soldiers “legitimate targets.”

Zelensky insists Ukraine needs stronger security guarantees to stop future Russian aggression, but for now, Kyiv is counting on allies to respond.
