The court gave a life sentence to a 21-year-old Russian army sergeant for shooting and killing an unarmed Ukrainian man during the first days of the war. Its the first war crimes trial of the war.

The widow asked the Russian soldier what he felt when he killed her husband. "Fear," he said. "I understand you probably won't be able to forgive me. But I ask for your forgiveness."

A Russian sergeant pleads guilty for killing a Ukrainian civilian in the war's first war crimes case. Such cases usually occur after a war ends. Ukraine wants to prosecute while the evidence is fresh.

Russia was expected to dominate the skies over Ukraine. But Ukrainians are still shooting down helicopters and planes, making Russian pilots very wary about venturing into Ukrainian airspace.

Ukrainian President Volodymyr Zelenskyy called the visit a signal of bipartisan support from the U.S. Congress. The meeting took place as Ukraine said it had forced Russian troops away from Kharkiv.

Ukraine is prosecuting a member of the Russian military, alleging he killed an unarmed Ukrainian civilian. The prosecutor general says Ukraine is preparing 41 more cases.

Russian forces have been active in multiple former Soviet republics this year, a reflection of Russian leader Vladimir Putin's desire to maintain a 'sphere of influence' beyond Russia's borders.

The focus is Ukraine, but Russian troops have been in five former Soviet republics this year — a reflection of Vladimir Putin's desire to maintain a "sphere of influence" beyond Russia's borders.

Russia had a reputation for being highly skilled in secretive military communications. That notion has been largely shattered by the bumbling way it has been operating in Ukraine.

When Russia invaded Ukraine eight weeks ago, its war plan failed on multiple fronts. Russia has now regrouped and is focused on the east of Ukraine, hoping to avoid the earlier mistakes.

CIA Director Bill Burns made a rare public speech Thursday and talked about the agency's role in Ukraine. Also, hundreds of suspected Russian spies have been kicked out of embassies in Europe.

Russia is now concentrating its forces in eastern Ukraine and a major offensive is widely anticipated. But this new stage of the war could differ in many ways from the past seven weeks of fighting.

Ukraine's military has fought so effectively that Russia abandoned its initial plan, which envisioned a quick takeover of Kyiv. Now Russia has a new approach, which focuses on eastern Ukraine.

The Russians are pulling some troops away from Ukraine's capital Kyiv. But what exactly does this mean? U.S. and Ukrainian officials suspect Moscow may just be pausing before another big offensive.

Russia says it put its nuclear forces on a higher state of alert, and Western officials have raised the prospect of chemical weapons attacks. How serious are these threats?

Russia's war in Ukraine has prompted an exodus from Russia, including many Americans living there. Some had built a life stretching over decades. Now they don't know if they'll ever go back.

Ukraine may be outgunned, but to the surprise of many, it has punched back hard against Russia. The U.S. is supplying lots of Ukraine's most effective weapons, which are coming into the country daily.

Ukraine is outgunned by Russia but is making the most of its mobile weapons that allow Ukrainian troops to be more nimble. Some of the most important weapons are from the United States.

The package by the White House includes missiles to take out tanks and bring down Russian aircraft — as well as drones that the U.S. hasn't provided previously.

The U.S. and Russia have talked for years about "hybrid war" — waging a conflict on multiple fronts beyond the battlefield. In unprecedented ways, the U.S. is now employing this against Russia.
