Waves of Russian missiles pounded a military training base close to Ukraine’s western border with NATO member Poland, killing 35 people.

The strike followed Russian threats to target foreign weapon shipments that are helping Ukrainian fighters defend their country against Russia’s grinding invasion.

More than 30 Russian cruise missiles targeted the sprawling training facility that is less than 25 kilometers (15 miles) from the closest border point with Poland, according to the governor of Ukraine’s western Lviv region.

Poland is a key location for routing Western military aid to Ukraine.

Since Russia invaded Ukraine, Lviv had largely been spared the scale of destruction unfolding further east and become a destination for residents escaping bombarded cities and for many of the nearly 2.6 million refugees who have fled the country.

The training center in Yavoriv appears to be the most westward target struck so far in the 18-day invasion.

The facility, also known as the International Peacekeeping and Security Center, has long been used to train Ukrainian military personnel, often with instructors from the United States and other NATO countries.

It has also hosted international NATO drills. As such, the site symbolizes what has long been a Russian complaint: That the NATO alliance of 30 member countries is moving ever closer to Russia’s borders. Russia has demanded that Ukraine drop its ambitions to join NATO.

Lviv governor Maksym Kozytskyi said most of the missiles fired Sunday “were shot down because the air defense system worked.” The ones that got through killed at least 35 people and wounded 134, he said.

Russian fighters also fired at the airport in the western city of Ivano-Frankivsk, which is less than 150 kilometers (94 miles) north of Romania and 250 kilometers (155 miles) from Hungary, countries that also are NATO allies. The airport, which includes a military airfield as well as a runway for civilian flights, also was targeted Friday.

Fighting also raged in multiple areas of the country overnight. Ukrainian authorities said Russian airstrikes on a monastery and a children’s resort in the eastern Donetsk region hit spots where monks and refugees were sheltering, wounding 32 people.

Another airstrike hit a westward-bound train evacuating people from the east, killing one person and injuring another, Donetsk’s chief regional administrator said.

To the north, in the city of Chernihiv, one person was killed and another injured in a Russian airstrike that destroyed a residential block, emergency services said.

Around the capital, Kyiv, a major political and strategic target for the invasion, fighting also intensified, with overnight shelling in the northwestern suburbs and a missile strike Sunday that destroyed a warehouse to the east.

In Irpin, a suburb about 12 miles (20 kilometers) northwest of central Kyiv, bodies lay out in the open Saturday on streets and in a park.

“When I woke up in the morning, everything was covered in smoke, everything was dark. We don’t know who is shooting and where,” resident Serhy Protsenko said as he walked through his neighborhood. Explosions sounded in the distance. “We don’t have any radio or information.”

According to AP, the chief regional administrator, Oleksiy Kuleba, said Russian forces appeared to be trying to blockade and paralyze the capital with day and night shelling of the suburbs. Kuleba said Russian agents were in the capital and its suburbs, marking out possible future targets.

He vowed that any all-out assault would meet stiff resistance, saying: “We’re getting ready to defend Kyiv, and we’re prepared to fight for ourselves.”

Talks aimed at reaching a cease-fire again failed Saturday, and the U.S. announced plans to provide another $200 million to Ukraine for weapons. Russian Deputy Foreign Minister Sergei Ryabkov warned other nations that sending equipment to bolster Ukraine’s military was “an action that makes those convoys legitimate targets.”

Russian soldiers pillaged a humanitarian convoy that was trying to reach the battered and encircled port city of Mariupol, where more than 1,500 people have died, a Ukrainian official said. Ukraine’s military said Russian forces captured Mariupol’s eastern outskirts, tightening their siege of the strategic port. Taking Mariupol and other ports on the Azov Sea could allow Russia to establish a land corridor to Crimea, which it seized from Ukraine in 2014.

Ukrainian President Volodymyr Zelenskyy accused Russia of trying to break his country apart, as well as starting “a new stage of terror” with the alleged detention of a mayor from a city west of Mariupol.

“Ukraine will stand this test. We need time and strength to break the war machine that has come to our land,” Zelenskyy said during his nightly address to the nation Saturday.

Zelenskyy reported that 1,300 Ukrainian soldiers had died since the Russian invasion began on February 24, 2022.
