LVIV, Ukraine (AP) — Russia launched its long-feared, full-scale offensive to take control of Ukraine’s east, Ukrainian President Volodymyr Zelenskyy announced Monday.
“Now we can already state that the Russian troops have begun the battle for the Donbas,” he said in a video address. Zelenskyy said a “significant part of the entire Russian army is now concentrated on this offensive.”
The Donbas is Ukraine’s mostly Russian-speaking industrial heartland in the east, where Moscow-backed separatists have been fighting Ukrainian forces for the past eight years and have declared two independent republics that have been recognized by Russia.
In recent weeks, the Kremlin declared the capture of the Donbas its main goal of the war after its attempt to storm Kyiv failed. After withdrawing from the capital, it began regrouping and reinforcing its ground troops in the east for what could be a climactic battle.
“No matter how many Russian troops are driven there, we will fight,” Zelenskyy vowed. “We will defend ourselves. We will do it every day.”
The Ukraine military’s general staff said Russian forces Monday were increasing assaults in the Luhansk and Donetsk regions — both of which are part of the Donbas — as well as in the area of Zaporizhzhia.
It also said Russia was sending reinforcements to the Crimean Peninsula — seized from Ukraine in 2014 — and to the Rostov-on-Don area, which borders Ukraine.
Witnesses in key cities Kharkiv and Bakhmut near the front line saw no immediate sign of increased military activity there. Associated Press journalists reported hearing distant artillery fire in some areas, but that has happened sporadically for weeks.
The announcement from Zelenskyy came as Russia bombarded the western city of Lviv and a multitude of other targets across Ukraine in what appeared to be an intensified bid to grind down the country’s defenses.
At least seven people were reported killed in the missile strikes on Lviv, a city close to the Polish border that has seen only sporadic attacks during almost two months of war and has become a haven for civilians fleeing the fighting elsewhere. To the Kremlin’s increasing anger, Lviv has also become a major gateway for NATO-supplied weapons.
In other developments, a few thousand Ukrainian troops, by Russia’s estimate, remained holed up at a mammoth steel mill in Mariupol, the last known pocket of resistance in the devastated southern port city.
And Zelenskyy submitted a filled-out questionnaire in the first step toward obtaining membership in the European Union — a desire that has been a source of tension with Moscow for years.
The Russian attack on Lviv hit three military infrastructure facilities and an auto shop, according to the region’s governor, Maksym Kozytskyy. He said the wounded included a child.
A Lviv hotel sheltering Ukrainians who had fled the fighting in other parts of the country was also badly damaged, Mayor Andriy Sadovyi said. The city has seen its population swell with elderly people, mothers and children trying to escape the war.
“The nightmare of war has caught up with us even in Lviv,” said Lyudmila Turchak, who fled with two children from the eastern city of Kharkiv. “There is no longer anywhere in Ukraine where we can feel safe.”
Lviv, the biggest city and a major transportation hub in western Ukraine, is about 80 kilometers (50 miles) from Poland, a NATO member.
Russia has strongly complained about the increasing flow of Western weapons to Ukraine and warned that such aid could have consequences. On Russian state media, some anchors have charged that the supplies amount to direct Western engagement in the fight against Russia.
A powerful explosion also rocked Vasylkiv, a town south of the capital of Kyiv that is home to an air base, according to residents. It was not immediately clear what was struck.
Kharkiv, Ukraine’s second-largest city, was hit by shelling that killed at least three people, according to Associated Press journalists on the scene. One of the dead was a woman who appeared to be going out to collect water in the rain. She was found with a water canister and an umbrella by her side.
Military analysts say Russia was increasing its strikes on weapons factories, railroads and other infrastructure ahead of its assault on the Donbas.
Moscow said its missiles struck more than 20 military targets in eastern and central Ukraine in the past day, including ammunition depots, command headquarters and groups of troops and vehicles.
It also reported that its artillery hit an additional 315 Ukrainian targets and that warplanes conducted 108 strikes on troops and military equipment. The claims could not be independently verified.
Gen. Richard Dannatt, a former head of the British Army, told Sky News that Russia is waging a “softening-up” campaign ahead of the Donbas offensive.
A senior U.S. defense official, speaking on condition of anonymity to discuss the Pentagon’s assessments of the war, said there are now 76 Russian combat units, known as battalion tactical groups, in eastern and southern Ukraine, up from 65 last week.
That could translate to around 50,000 to 60,000 troops, based on what the Pentagon said at the start of the war was the typical unit strength of 700 to 800 soldiers, but the numbers are difficult to pinpoint at this stage in the fighting.
The official also said that four U.S. cargo flights arrived in Europe on Sunday with an initial delivery of weapons and other materials for Ukraine as part of a $800 million package announced by Washington last week. And training of Ukrainian personnel on U.S. 155 mm howitzers is set to begin in the next several days.
The capture of Mariupol, where Ukraine estimates 21,000 people have been killed, is seen as key, and not just because it would deprive Ukraine of a vital port and complete a land bridge between Russia and the Crimean Peninsula.
The U.S. defense official said that if Russian forces succeed in taking full control of Mariupol, that could free up nearly a dozen battalion tactical groups for use elsewhere in the Donbas.
