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.

Negotiations between Ukraine and Russia are "very difficult" but "moving forward," Ukrainian President Volodymyr Zelenskyy said Wednesday.
"It's very difficult, sometimes confrontational," Zelenskyy said in an early morning address. "But step by step, we are moving forward."
Zelenskyy added that he is "grateful to all international mediators who are standing up for Ukraine."
Ukrainian President Volodymyr Zelenskyy will virtually address a NATO summit in Brussels on Thursday, his office confirmed to ABC News.
"We are still working on the format," his office said in a statement.
A NATO official also confirmed to ABC News that Zelenskyy will address the Extraordinary Summit of NATO Heads of State + Government and that they are still finalizing the details.
It is unclear if Zelenskyy will prerecord a statement or participate in the discussion.

The besieged Ukrainian city of Mariupol seems to be facing particular brutalization by Russian forces, including "some of the most egregious accounts of what could constitute war crimes," U.S. Department of State spokesperson Ned Price said Tuesday.
The southeastern coastal city's strategic location could be a factor, Price told reporters during a briefing. There may also be a "particular vengeance against this population," he added, with Putin "having been under the impression -- whether he was misinformed or just unwitting of reality -- that his forces would not be greeted as anything other than the aggressors that they are."
"Every day when it comes to potential atrocities, we are seeing, we are all witnessing additional evidence that the Russians are in fact committing atrocities, committing acts that may go above that threshold to include potential war crimes," Price said.
Price said the U.S. still hasn't confirmed Russia's claims that it has evacuated thousands of Ukrainian civilians from the city to Russian territory.

Russia's Defense Ministry claimed Tuesday that it has evacuated 366,182 people from Ukraine to Russia since the invasion began.
Russia said 19,442 people, including 3,448 children, were evacuated from the Luhansk and Donetsk regions to Russia on Monday, without the participation of Ukrainian authorities, Mikhail Mizintsev, the head of Russia's National Defense Control Center, claimed in a press briefing.
Mizintsev claimed more than 68,000 residents were also evacuated from Mariupol without the Ukrainian authorities' involvement.
He claimed these people "are now completely safe under the Russian Federation's protection, and all those in need are receiving necessary aid."
Russia claimed it opened humanitarian corridors from Kyiv, Chernihiv, Sumy and Kharkiv on Tuesday.
