KYIV, Ukraine  — Explosions rattled Kyiv during daylight Monday as Russian ballistic missiles took aim at the Ukrainian capital, hours after a more common nighttime barrage of the city by drones and cruise missiles.

Russian forces fired 11 ballistic and cruise missiles at Kyiv at about 11:30 a.m. local time, Ukraine’s chief of staff Valerii Zaluzhnyi said. All of them were shot down, he said, and puffs of white smoke could be seen in the blue sky over the city from street level.

Debris from the intercepted missiles fell in Kyiv’s central and northern districts during the morning, landing in the middle of traffic on a city road and also starting a fire on the roof of a building, the Kyiv military administration said. At least one civilian was reported hurt.

The blasts unnerved some locals, already under strain after being awakened by the night attack.

“After what happened last night, I react sharply to every siren now. I was terrified, and I’m still trembling,” said Alina Ksenofontova, a 50-year-old woman who took refuge in the Kyiv subway with her dog Bublik.

The central station, Teatralna, was crowded with sheltering locals.

Artem Zhyla, a 24-year-old who provides legal services abroad, took his laptop with him and kept working underground.

“I heard two or three explosions, went to the bathroom, and then I heard five or seven more explosions,” Zhyla said. “That’s when I realized something terrible was happening.”

Like many others in the capital, he said he feels exhausted and stressed. However, he has no intention of giving up and plans to attend his yoga class to recharge.

“This is certainly not enough to break us,” he said.

Ukraine President Volodymyr Zelenskyy and first lady Olena Zelenska both posted a video of what they said were frightened school children running and screaming down a Kyiv street toward a bomb shelter as sirens wailed.

“This is what an ordinary weekday looks like,” the president wrote on Telegram, an instant messaging platform.

Russia used Iskander short-range missiles in the morning attack, the spokesman for Ukraine’s air force, Yurii Ihnat, said on local TV.

The missiles were fired from north of Kyiv, Ihnat said, without clarifying if he meant Russian territory. Kyiv is around 236 miles from the Russian border.

The Russian Defense Ministry said it launched a series of strikes early Monday targeting Ukrainian air bases with precision long-range air-launched missiles. The strikes destroyed command posts, radars, aircraft and ammunition stockpiles, it said. It did not say anything about hitting cities or other civilian areas.

Ukrainian Foreign Minister Dmytro Kuleba warned against indifference, saying the repeated strikes on civilian areas amounted to “war crimes.”

“Russia’s drone and missile attacks on peaceful Ukrainian cities cannot be seen as usual, no matter how frequent they grow,” he tweeted.

During the previous night, Ukraine air defenses brought down more than 40 targets as Russian forces bombarded Kyiv with a combination of drones and cruise missiles in their 15th nighttime attack on the capital so far this month, said Serhii Popko, the head of Kyiv’s military administration.

On Saturday night, Kyiv was subjected to the largest drone attack since the start of Russia’s war. At least one person was killed, local officials said.

The Kremlin’s strategy of long-range bombardment has brought many sleepless nights for Ukrainians.

Over the winter, Russian forces aimed their missiles and drones at power plants and other infrastructure. The apparent goal was to weaken Ukraine’s resolve and compel the Ukrainian government to negotiate peace on Moscow’s terms, but Ukrainians swiftly and defiantly repaired the damage.

In recent months, Ukraine has been receiving advanced air defense systems from its Western allies, improving its ability to fend off bombardments by the Kremlin’s forces.

The head of the International Atomic Energy Agency will speak Tuesday at the U.N. Security Council about safety at southeastern Ukraine’s Zaporizhzhia nuclear power plant, which is the largest in Europe and under Russian control and endangered by the fighting.

Mikhail Ulyanov, Russia’s ambassador to international organizations in Vienna, said IAEA head Rafael Grossi was expected to “set out specific ideas” about how to strengthen security at the plant.

Across the country, the Ukrainian air force said that over Sunday night it shot down 37 out of 40 cruise missiles and 29 of 35 drones launched by Kremlin forces.

Four civilians were killed and around two dozen others were injured, including three children and a pregnant woman, in Russian shelling elsewhere across the country, authorities said.

Russian warplanes dropped bombs Monday on the town of Toretsk, killing three civilians, Donetsk regional Gov. Pavlo Kyrylenko said.

Strikes on the eastern Dnipropetrovsk region killed two people, officials said.

Meanwhile, in the Belgorod region of Russia on the border with Ukraine, one person was killed by a Ukrainian shelling of the village of Grafovka, Gov. Vyacheslav Gladkov said.

Russian missiles also slammed into a military airport iIn the western Khmelnytskyi region of Ukraine, destroying five aircrafts and damaging the runway, local Gov. Serhyi Hamaliy said on TV.

The strike, he added, sparked fires at nearby warehouses storing fuel and military equipment.
