Russia's largest military shipbuilding and diamond mining firms were targeted.
Russian President Vladimir Putin's "special military operation” into Ukraine began on Feb. 24, with troops crossing the border from Belarus and Russia. Moscow's forces have since been met with “stiff resistance” from Ukrainians, according to U.S. officials.
Russian forces retreated last week from the Kyiv suburbs, leaving behind a trail of destruction. After graphic images emerged of civilians lying dead in the streets of Bucha, U.S. and European officials accused Russian troops of committing war crimes.

The Russian army is reluctant to engage in large-scale infantry operations, the British Ministry of Defense said Saturday.
"Russia continues to besiege a number of major Ukrainian cities including Kharkiv, Chernihiv and Mariupol. Russian forces are proving reluctant to engage in large scale urban infantry operations, rather preferring to rely on the indiscriminate use of air and artillery bombardments in an attempt to demoralize defending forces," the Ministry of Defense said in a statement posted online.
It added: "It is likely Russia will continue to use its heavy firepower on urban areas as it looks to limit its own already considerable losses, at the cost of further civilian casualties."

During a visit to Memphis, Tennessee, on Friday, First Lady Dr. Jill Biden privately met with two Ukrainian families who have loved ones being treated at St. Jude Children’s Research Hospital.
Four Ukrainian children, ages 20 months to 8 years, as well as 10 of their family members, were airlifted from Poland to St. Jude on Monday to continue treatment, according to Michael LaRosa, the First Lady's press secretary.
Biden said in remarks during her visit that her "heart has ached watching the videos" of devastation in Ukraine.
"Parents weeping over their child's broken bones … bodies in the streets. The senselessness of it all is just staggering,” she said.
She added, "When I learned that St. Jude was working with hospitals in Europe to bring some of the Ukrainian children with cancer and their families here, I felt so proud and I wanted to join you in welcoming them. We stand with Ukraine and we're praying for their families."

Fox News correspondent Benjamin Hall is back in the U.S. after suffering serious injuries while reporting in Ukraine, Fox News Media CEO Suzanne Scott said in a statement.
Hall was hurt in Horenka, outside of Kyiv, on March 14 when his vehicle was hit by incoming fire, Scott said at the time. Fox News cameraman Pierre Zakrzewski and Ukrainian producer and fixer Oleksandra "Sasha" Kuvshynova were killed in the incident.
Scott said Hall has been transferred from the Landstuhl Regional Medical Center in Germany to the Brooke Army Medical Center in Texas.
Hall has undergone multiple surgeries, Scott said.
"He remains in good spirits despite everything he has endured," Scott wrote. "His strength and resiliency in the face of this crisis has been nothing short of extraordinary."
