Ukraine has vowed to shed Russian blood in an "iron fist" counterattack after Moscow pummelled the country with airstrikes, killing at least 23 including three kids.
Defence Minister Oleskii Reznikov said Western weapons will give Kyiv a chance to punch through Russian lines with an "iron fist" in the hopes of reclaiming the territories occupied by Moscow.
Speaking to an online news briefing, he said: “As soon as there is God’s will, the weather and a decision by commanders, we will do it."
Within hours of the statement, an apparent Ukrainian drone strike lead to an enormous fuel tank blaze in the Crimean city of Sevastopol.
The Moscow-installed governor there, Mikhail Razvozhaev, has said the fire is still burning but it has been contained and no one is injured.
"The four fuel tanks that were hit, they are practically burnt out already," he said in a video posted on his Telegram channel.
He also said: "The situation is under control, forces and all necessary means are sufficient."
It comes after missile attacks included the first one against Kyiv in nearly two months, though there were no reports of targets hit.
The city government said Ukraine's air force intercepted 11 cruise missiles and two unmanned aerial vehicles over Kyiv.
The strikes on the nine-story residential building in central Ukraine occurred in Uman, a city located around 215 kilometers (134 miles) south of Kyiv. Twenty-one people died in that attack, according to Ukraine's National Police. They included two 10-year-old children and a toddler.
Another of the victims was a 75-year-old woman who lived in a neighboring building and suffered internal bleeding from the huge blast's shock wave, according to emergency personnel at the scene.
The Ukrainian national police said 17 people were wounded and three children were rescued from the rubble. Nine were hospitalized.
The bombardment was nowhere near the war's sprawling front lines or active combat zones in eastern Ukraine, where a grinding war of attrition has taken hold. Moscow has frequently launched long-range missile attacks during the 14-month war, often indiscriminately hitting civilian areas.
Ukrainian officials and analysts have alleged such strikes are part of a deliberate intimidation strategy by the Kremlin.
The Russian Defense Ministry said the long-range cruise missiles launched overnight were aimed at places where Ukrainian military reserve units were staying before their deployment to the battlefield.
"The strike has achieved its goal. All the designated facilities have been hit," Lt. Gen. Igor Konashenkov, the Defense Ministry's spokesperson, said. He didn't mention any specific areas or residential buildings getting hit.
Survivors of the Uman strikes recounted terrifying moments as the missiles hit when it still was dark outside.
Halyna, a building resident, said she and her husband were covered in glass by the blast. They saw flames outside their window and scrambled out, but first Halyna checked whether her friend in a neighboring apartment was OK.
"I was calling, calling her (on the phone), but she didn't pick up. I even rang the doorbell, but still no answer," she told The Associated Press. She used the spare keys from her friend's apartment and went inside to check on her. She found her lying dead on her apartment floor.
Halyna refused to provide her last name out of security concerns.
Another building resident, Olha Turina, told the AP that glass from the explosion flew everywhere.
Turina, whose husband is fighting on the front lines, said one of her child's classmates was missing.
"I don't know where they are, I don't know if they are alive," she said. "I don't know why we have to go through all this. We never bothered anyone."
Three body bags lay next to the building as smoke continued to billow hours after the attack. Soldiers, civilians and emergency crews searched through the rubble outside for more victims, while residents dragged belongings out of the damaged building.
One woman, crying in shock, was taken away by rescue crews for help.
Yulia Norovkova, spokeswoman for emergency rescue crews on the scene, said local volunteers were helping nearly 150 emergency personnel. Two aid stations, including psychologists, were operating, she said.
A 31-year-old woman and her 2-year-old daughter were also killed in the eastern city of Dnipro in another attack, regional Governor Serhii Lysak said. Four people were wounded, and a private home and business were damaged.
The attacks came days after President Volodymyr Zelenskyy said that he and Chinese leader Xi Jinping held a "long and meaningful" phone call where Xi said his government will send a peace envoy to Ukraine and other nations.
Ukrainian Foreign Minister Dmytro Kuleba said Friday's bombardment showed the Kremlin isn't interested in a peace deal.
"Missile strikes killing innocent Ukrainians in their sleep, including a 2-year-old child, is Russia's response to all peace initiatives," he tweeted. "The way to peace is to kick Russia out of Ukraine."
Czech President Petr Pavel, on a visit to Ukraine, was unconvinced by the Kremlin's past denials of responsibility for such bloodshed.
"The number of attacks on civilian targets leads to an only conclusion that it is intentional," Pavel told Czech media. "It's a clear plan intended to cause chaos, horrors among the civilian population."
Shortly after Moscow unleashed the barrage, the Russian Defense Ministry posted a photo on Telegram showing a missile launch and saying, "Right on target."
The message triggered outrage among Ukrainians on social media and some officials, who viewed it as gloating over the casualties.
"The Ministry of Homicide of the Russian Federation is happy that it hit a residential building with a rocket and killed civilians," said Andriy Yermak, the head of Ukraine's presidential office.
In Kyiv, fragments from intercepted missiles or drones damaged power lines and a road in one neighborhood. No casualties were reported.
