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.

Ukraine's presidential adviser Mykhailo Podolyak has tweeted that Ukraine and Russia are taking a "technical pause" in negotiations until Tuesday.
While the first three rounds of talks were held in Belarus, this fourth round is held remotely.
"Negotiations continue," Podolyak tweeted.
Ukrainian President Volodymyr Zelenskyy will address U.S. lawmakers virtually at 9 a.m. Wednesday, according to a letter from House Speaker Nancy Pelosi and Senate Majority Leader Chuck Schumer.
Only members of Congress will be allowed in the auditorium where Zelenskyy's remarks will be broadcast, but the event will be livestreamed.
"The Congress remains unwavering in our commitment to supporting Ukraine as they face Putin’s cruel and diabolical aggression, and to passing legislation to cripple and isolate the Russian economy as well as deliver humanitarian, security and economic assistance to Ukraine," the letter said. "We look forward to the privilege of welcoming President Zelenskyy’s address to the House and Senate and to convey our support to the people of Ukraine as they bravely defend democracy."

More than 2.8 million people have fled Ukraine since Russia invaded, the U.N. Refugee Agency said on Monday.
Monday’s update said more than 1.72 million people have crossed the border into Poland, but didn’t include updated figures for crossings into all the other countries that border Ukraine.
Rafal Trzaskowski, mayor of Warsaw, Poland, told The Telegraph on Saturday that his city’s ability to absorb refugees fleeing the Ukraine war was “at an end” and that the city would be overwhelmed unless an international relocation system was created.
“We are doing all we can but we cannot rely on improvisation anymore,” Trzaskowski told the newspaper. “We coordinate our work with other mayors in Poland and in Europe, and through this we send buses of refugees to other cities. But we are doing this on our own. We need a European relocation system which will organise it because it is a huge logistical enterprise. We can’t improvise anymore.”

Russian attacks on Ukraine will increase, with the western city of Lviv among potential targets, a senior U.S. official told ABC News.
Russian officials are convinced the city is being used to stage military operations and that some high ranking people are present. Russia may target the city, since “they want to create more terror,” an official said.
Russians have warned that anyone who supplies weapons to Ukraine, or offers safe haven, could be targeted.
After Sunday’s attack near the Polish border, concern is growing over a possible strike in Poland, an official said. There are several areas in Poland where weapons are currently being staged or stored.
