A Russian airstrike on a base in western Ukraine kills 35 people.

Russian missiles slammed into a military training facility on Ukraine's western border with NATO member Poland, killing 35 people. The operation came in response to Russian threats to target international weapon shipments that are assisting Ukrainian fighters in defending their country against Russia's onslaught.

According to the governor of Ukraine's western Lviv region, more than 30 Russian cruise missiles targeted the huge training complex, which is fewer than 25 kilometres (15 miles) from the nearest border point with Poland. Poland is an important transit point for Western military aid to Ukraine.

Since Russia's invasion of Ukraine, Lviv has been largely spared the amount of destruction unfolding farther east, becoming a destination for citizens fleeing bombed areas as well as many of the approximately 2.6 million refugees who have fled the country.

So far in the 18-day invasion, the training complex in Yavoriv appears to be the most westward target attacked. The International Peacekeeping and Security Center, as it is often known, has long been used to train Ukrainian military troops, often with instructors from the United States and other NATO countries.

It has also served as a venue for multinational NATO drills. As such, the site reflects a long-standing Russian complaint: that the NATO alliance of 30 member countries is encroaching on Russia's boundaries.

Another airstrike damaged a westbound train transporting people from the east, killing one and wounded another, according to Donetsk's chief regional administrator.

To the north, in the city of Chernihiv, a Russian airstrike destroyed a residential block, killing one person and injuring another, according to emergency services.

Fighting intensified around the capital, Kyiv, a major political and strategic target for the invasion, with nighttime shelling in the northwestern suburbs and a missile strike Sunday that destroyed a warehouse to the east.

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

"When I got up in the morning, everything was shrouded in smoke and gloomy." "We don't know who is firing or where," Serhy Protsenko, a resident, said as he strolled through his neighbourhood. Explosions could be heard in the distance. "We don't have a radio or access to information."

Russian forces appeared to be attempting to blockade and cripple the capital with day and night shelling of the suburbs, according to chief regional administrator Oleksiy Kuleba. According to Kuleba, Russian spies were scouting potential future targets in the capital and its outskirts.

He pledged that any all-out assault would be met with severe resistance, stating, "We're preparing to protect Kyiv, and we're ready to fight for ourselves."

Talks to achieve a cease-fire failed again on Saturday, and the United States revealed intentions to transfer another $200 million to Ukraine for weaponry. Russian Deputy Foreign Minister Sergei Ryabkov cautioned other countries that supplying military supplies to Ukraine was "an action that renders those convoys legitimate targets."
