Kyiv was hit Friday by some of the most powerful explosions heard since Russian forces withdrew from the area two weeks ago. Moscow said it had struck a plant in capital that made and repaired Ukrainian missiles, including anti-ship missiles.
“The number and scale of missile strikes on targets in Kyiv will increase in response to any terrorist attacks or acts of sabotage on Russian territory committed by the Kyiv nationalist regime,” the Russian Defense Ministry said in a statement.
Kirill Kyrylo, 38, a worker at a car repair shop, said he had seen three blasts hit an industrial building across the street, causing a blaze that was later put out by firefighters.
“The building was on fire, and I had to hide behind my car,” he said, pointing out the shattered glass of the repair shop and bits of metal that had flown over from the burning building across the street.
Russia’s defense ministry also said it had captured the Ilyich steel works in Mariupol, one of the last industrial areas holding out in the besieged eastern city that has seen the war’s heaviest fighting and the worst humanitarian catastrophe.
Ukraine said it had repelled Russian offensives in the town of Popasna and Rubizhne, in an area north of Mariupol. Both reports could not be independently confirmed.
Russia pulled its troops out of northern Ukraine this month after a huge, armored assault on Kyiv was repelled at the outskirts of the capital.
Moscow now says its main war aim is capturing the Donbas, an eastern region of two provinces that are already partly held by Russian-backed separatists and that Russia wants Kyiv to cede.
It has sent a new column of thousands of troops into the east for what Ukraine anticipates will be a major assault.
Moscow says it hopes to seize all of Mariupol soon, which would be the only big city it has captured so far.
The Black Sea port, home to 400,000 people before the war, has been reduced to rubble by seven weeks of siege and bombardment, with tens of thousands of people trapped inside.
Thousands of civilians have died there.
Russia initially described its aims in Ukraine as disarming its neighbor and defeating nationalists there. Kyiv and its Western allies say those are bogus justifications for an unprovoked war of aggression that has driven a quarter of Ukraine’s 44 million people from their homes.
