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.

Russian troops on the move ahead of expected Ukrainian counteroffensive
The Ukrainian Armed Forces said on Monday Russian troops were massing in the direction of the town of Kryvyi Rih in the Dnipropetrovsk region, possibly in a bid to prepare for a large Ukrainian counterattack.
Talk of a major Ukrainian counteroffensive aimed at taking back the southern city of Kherson, about 140 miles south of Kryvyi Rih, has been gathering pace for several weeks.
The Ukrainian military also issued the maximum missile-fire-threat alert on Sunday in reaction to Russian troops massing in the Black Sea.
At least 17 warships and boats of the Russian Black Sea fleet were maneuvering near the Crimean coast on Sunday, according to Ukrainian military officials.

Among them were six Kalibr cruise missile carriers with more than 40 high-precision missiles on board, as well as four large landing ships.
Russia has also been transferring a large number of troops to occupied Crimea, Vadym Skibitskyi, of the Ukrainian Ministry of Defense, said on Monday.
Russia plans to deploy these troops in the south of Ukraine to conduct future combat operations, Skibitskyi said.
The official added that Russia withdrew tactical groups of airborne troops from the eastern Donetsk region and transferred them to occupied Kherson about two weeks ago.
Russian forces have resumed localized ground attacks northwest and southwest of Izyum over the weekend and may be setting conditions for offensive operations further west into Kharkiv Oblast or toward Kharkiv City, the Institute for the Study of War said in its latest report.

A 'day of relief for the world' as Ukrainian grain shipments resume
Ukrainian Minister of Foreign Affairs Dmytro Kuleba called Monday a "day of relief for the world" as his country resumed grain shipments for the first time since Russia's offensive began.
"The day of relief for the world, especially for our friends in the Middle East, Asia, and Africa, as the first Ukrainian grain leaves Odesa after months of Russian blockade," Kuleba wrote in a post on Twitter. "Ukraine has always been a reliable partner and will remain one should Russia respect its part of the deal."

Ukrainian lawmaker hails departure of 1st grain ship a 'historic moment'
Watching as the first ship carrying Ukrainian grain set off from Odesa's port on Monday morning, Ukrainian lawmaker Oleksiy Honcharenko called it "Ukraine's victory" over Russia.
Honcharenko, the son of a former Odesa mayor, said this "historic moment" was only possible because Ukraine had inflicted so much damage on the Russian Navy and had liberated nearby Snake Island, forcing Russian President Vladimir Putin to make a deal.
"It shows again the the language of force is the only language Putin understands," Honcharenko told ABC News.
The Sierra Leone-flagged cargo ship Razoni leaves the port in Odesa, Ukraine, on Aug. 1, 2022, after restarting grain exports amid Russia's invasion of Ukraine, Ukraine August 1, 2022.

Honcharenko said he believes 16 more ships in the port will now begin moving out in the coming days. But he cautioned that he thinks Putin will now try to do everything to limit the ships coming in and out to a minimum within the U.N.-brokered deal, utilizing airstrikes near Ukrainian ports as well as trying to invent bureaucratic obstacles.
The next big test of the deal will be when the first ships come to enter Odesa, which Honcharenko said is expected at the end of this week.
