Russia-Ukraine updates: 2 US veterans who joined Ukrainian forces missing

Canadian artist Ivanka Siolkowsky is trying to restore some beauty to the war-ravaged Ukrainian city of Bucha.

A former school teacher, Silokowsky has been painting flowers and butterflies around bullet holes she finds in fences, walls of buildings and homes, frequently soliciting children and other local residents to help her.

"The project began a few weeks ago. I only painted 5 fences, but my hope is that the people of Bucha and other formerly occupied cities in Ukraine will continue this project further," Siolkowsky recently wrote on her Instagram page.

Bucha, which is northwest of Kyiv, is one of the most heavily bomb cities in Ukraine, where residents have told ABC News of witnessing numerous killings and torture at the hands of Russian forces.

Siolkowsky conceded that her paintings are not masterpieces and said someone commented on one of the Instagram posts, writing, “the paintings aren’t even good.”

"Believe me, I’m aware," she wrote on Instagram. "But the point of this wasn’t to create masterpieces -- it was to bring joy back into a city filled with darkness after the Russian occupation."

U.S. Defense Secretary Lloyd Austin convened the second monthly meeting of the Ukraine Contact Group Monday morning, during which more than 40 nations participated virtually.

"This gathering is virtual, but our efforts together are making a very concrete difference on the battlefield," Austin told the group as he faced two large monitors showing the virtual participants. "We're all here today because of the extraordinary valor and resilience of Ukraine soldiers and citizens."

The group was formed last month to help coordinate international efforts to support Ukraine in its fight against the Russian invaders.

"For three months, Ukraine has been fighting with grit and tactical ingenuity against an entirely unprovoked invasion by its far larger neighbor," Austin said. "And we're here to help Ukraine for the long haul."

Defense leaders from 44 countries and representatives of NATO and the European Union participated in the meeting. Several new nations joined the group since its first meeting, including Austria, Bosnia and Herzegovina, Colombia, Ireland and Kosovo.

Ukrainian officials, including Minister of Defense Oleksii Reznikov, also logged on to the virtual meeting.

"My friends, we've got your back -- all of us," Austin told the Ukrainian representatives. "President Zelenskyy and Ukraine's leaders have made history, and your forces have inspired the free world with their courage and skill."

Starbucks announced on Monday its decision to exit the market in Russia.

"We continue to watch the tragic events unfold and, today, we have decided to suspend all business activity in Russia, including shipment of all Starbucks products," Starbuck CEO Kevin Johnson said in a statement. "Our licensed partner has agreed to immediately pause store operations and will provide support to the nearly 2,000 partners in Russia who depend on Starbucks for their livelihood."

The announcement comes after the company suspended all business activity in Russia on March 8. Going forward, Starbucks said it will continue to pay its employees in Russia for six months.

Starbucks is one of multiple major U.S. and international companies that have put operations on hold in Russia because of the invasion of Ukraine. Other companies that have suspended operations there include Pfizer, Apple, FedEx, McDonald's and Amazon.

A Ukrainian court in Kyiv sentenced a 21-year-old Russian soldier to life in prison in the first war crimes trial since Russia’s invasion began in February.

Sgt. Vadim Shishimarin pleaded guilty and confessed in court last week to killing a 62-year-old Ukrainian man a few days into the Russian invasion.

During the trial, the widow of the man Shishimarin killed testified that her husband meant everything to her and said she believes the Russian soldier deserves life in prison.

However, the widow said she would support exchanging Shishimarin for any of the Ukrainian soldiers taken prisoner this month by Russia at the Azovstal steel plant in Mariupol, Ukraine.

"I feel very sorry for him," the widow testified. "But for a crime like that I can't forgive him."
