Russia bombs Kiev and other regions in massive attack with drones and missiles.

(Reuters) – Russia launched hundreds of drones and missiles against Kiev and other parts of Ukraine in the early hours of Sunday, killing at least four people and injuring dozens, in one of the most intense attacks against the capital since the start of the large-scale war.

Neighboring Poland closed its airspace near two cities in the southeast of the country and scrambled fighter jets from its air force in response, until the danger had passed.

The Ukrainian army reported that Russia launched 595 drones and 48 missiles overnight, of which 568 drones and 43 missiles were shot down by air defenses. It emphasized that the main target of the offensive was the capital, Kyiv.

President Volodymyr Zelensky said the attack, which lasted more than 12 hours, targeted a cardiology clinic, factories, and residential buildings.

Russia's Defense Ministry said on Sunday that it had carried out a "massive" attack against Ukraine using long-range weapons launched from the air and sea, as well as drones, to target military infrastructure, including airfields. Moscow denies attacking civilians in its war against Ukraine, although thousands have been killed and residential areas widely destroyed by its offensives.

Zelensky calls for action from international partners.

Zelensky reiterated his call for the international community to act decisively to cut off Russia's energy revenues that are financing the invasion. So far, Ukraine has failed to convince US President Donald Trump to impose punitive sanctions against Moscow.

"The time for decisive action has passed, and we are counting on a strong response from the United States, Europe, the G7, and the G20," he stated on the Telegram messaging app.

Kyiv awoke to loud explosions, drones flying overhead, and the roar of air defenses. Smoke from one of the hit locations billowed into the morning sky as the air raid alert ended at 9:13 a.m. (6:13 GMT), nearly seven hours after the attack began.

Reuters journalists visited an area on the outskirts of Kyiv where rows of newly built houses were almost completely destroyed and parked cars had been crushed by falling debris.

Residents sifted through the rubble of a residential building after its windows were shattered by the force of the explosion. Some people ran to underground metro stations, from where they followed the events on their cell phones.

Ukrainian defenses under pressure from large-scale attacks.

Attacks on this scale have put Ukraine's limited air defenses to the test throughout 2025. Zelensky stated on Saturday that a new Patriot missile system, supplied by Israel, had already been deployed, and that he expected two more to arrive by the fall.

He and other officials have been requesting more support from international partners to protect Ukraine's skies, but air defense systems are limited and other nations are also seeking to strengthen their own defenses in the face of perceived threats from Russia.

Zelensky stated that Sunday's attack hit several regions, including the southern city of Zaporizhzhia, where authorities said at least 16 people were injured.

Emergency services reported that at least four people were killed, while local authorities reported 67 injured across the country.

Among the fatalities is believed to be a 12-year-old girl, although this has not yet been officially confirmed, said Tymur Tkachenko, head of the military administration in Kyiv, on Telegram.
