Russian President Vladimir Putin's "special military operation" into neighboring Ukraine began on Feb. 24, with Russian forces invading from Belarus, to the north, and Russia, to the east. Ukrainian troops have offered "stiff resistance," according to U.S. officials.
The Russian military has since launched a full-scale ground offensive in eastern Ukraine's disputed Donbas region, capturing the strategic port city of Mariupol and securing a coastal corridor to the Moscow-annexed Crimean Peninsula.

More of Russia's 'barbarism,' Biden says of Kyiv strike
President Joe Biden on Sunday said Russia's early morning missile strikes on Kyiv were an act of "barbarism."
As Biden stood alongside German Chancellor Olaf Scholz at the official G7 welcome ceremony, ABC News' Karen Travers asked if he had any reaction to the strikes on a residential neighborhood.
"Yes, it's more of their barbarism," Biden said.
A missile struck an apartment block in Shevchenkivskyi, near central Kyiv, on Sunday morning, killing at least one and trapping others in the rubble, local officials said.

US to ban Russian gold imports
The Biden administration and other G7 leaders will announce on Sunday an import ban on Russian gold.
"This is a key export, a key source of revenue alternative for Russia, in terms of their ability to transact in the global financial system,” a senior administration official told reporters on a briefing call about the G7 summit in Germany. “Taking this step cuts off that capacity and again, is an ongoing illustration of the types of steps that the G7 can take collectively to continue to isolate Russia and cut it off from the global economy.”
The Treasury Department is expected to issue an official notice on Tuesday.
Gold is Russia's second largest export after oil and a source of significant revenue, but much of Russia's gold exportation has already been cut off in practice by banks, refiners and shippers. The move on Sunday marks an official severance of Russia from the world's gold market.
The U.S. and U.K. are participating in Sunday's announcement, but it is unclear whether all G7 countries will participate in the initiative. A Biden administration official tried to downplay concerns about potential disunity among G7 member states, pivoting instead to a talking point about efforts to cut off all financial pathways for Russia.
Pressed on whether Russia could continue to export gold by going through a country that does not participate in the ban, officials insisted the ban will be effective.
"We will continue to identify places where evasion as a risk continue to take steps to block off those pads,” an official said. “And the measuring gold in some ways is in fact, another step forward to block off ways that that Russia might seek to engage with the financial system, by virtue of all the other ways that have now been cut off to them.”

Missiles strike central Kyiv residential neighborhood
A series of Russian missiles struck a residential area of Kyiv, Ukraine, on Sunday morning, local officials said.
"Friends! Search and rescue operations are underway in a residential building in the Shevchenkivskyi district where a missile hit," Mayo Vitaliy Klychko said on Telegram. "There are people under the rubble. Some residents were evacuated, two victims were hospitalized. Rescuers continue to work, medics are on site."
At least one residential building appeared to have had sections of its facade sheared off, photos from the scene showed. Emergency responders could be seen working on the upper floors of the building as smoke rose into the morning sky.
"Several explosions in the Shevchenkivskyi district," Klychko said. "Ambulance crews and rescuers on the spot. Residents are being rescued and evacuated in two houses."
At least one missile was shot down by Ukrainian air defenses, Oleksiy Kuleba, head of the Kyiv regional administration, said on Telegram.
"The remains of the missile fell on the outskirts of one of the villages in the area," Kuleba said.
