Russian invasion of Ukraine: A visual timeline of the war

Almost a year after Russian President Vladimir Putin launched a full-scale invasion of neighboring Ukraine, the two countries are engaged in a struggle for control of areas throughout the east and south.

Putin's forces pulled out of key positions in November, retreating from Kherson as Ukrainian troops led a counteroffensive targeting the southern port city. Russian drones have continued bombarding civilian targets throughout Ukraine, knocking out critical power infrastructure as winter sets in.

China pushes back against US claims it may supply weapons to Russia

The United States' claims that they have intelligence showing China plans to provide weapons to Russia to assist in the ongoing war in Ukraine will impede the "political settlement of the Ukrainian crisis" and "will also further damage" China-US relations, Chinese Foreign Ministry spokesperson Wang Wenbin said during a press conference Thursday.

Wenbin called US claims of intelligence "nothing more than catching up on the wind, slandering and discrediting China."

"Since the outbreak of the crisis in Ukraine, China has been steadfast in dialogue. While standing on peace, it has persuaded and introduced peace in its own way and played a constructive role in resolving the crisis in line with the situation," Wenbin said.

"The vast majority of refugees and internally displaced Ukrainians – some 77% and 79%, respectively – want to return home one day, however, only 12% of both refugees and [internally displaced people] plan to do so in the next three months," the UNHCR said in a press release.

Ukraine advances in south, Russia says

Ukrainian forces on Sunday evening broke through part of Russia's defense of the disputed Kherson region, advancing from the region’s northeast into a territory Russia had claimed to annex as its own on Friday.

Ukrainian troops succeeded in pushing south along the Dnipro river, according to Ukrainian and Russian officials.

Russia's Defense Ministry on Monday partly confirmed the advance, saying Ukrainian forces "managed to drive a wedge deep into our defense."

It said Russian troops had fallen back to “pre-prepared lines of defense" and were using heavy artillery to halt a further Ukrainian advance. It claimed, without evidence, that Ukraine had suffered heavy losses, but acknowledged that Ukraine had an advantage in tank numbers there.

Russian military bloggers said on Sunday that Ukrainian troops advanced southwards in the direction of the village of Dudchany, several miles behind the rest of Russia's frontline in the region.

The advance raised questions about whether Russia would be able to hold the city of Kherson, the only regional capital it managed to seize in the invasion. For weeks, military experts have said Russia's position in the Kherson region has been deteriorating because Ukraine has destroyed the only bridges allowing Russia to re-supply its troops.

Kirill Stremousov, a Russian-installed official in the region, on social media acknowledged Ukrainian troops had advanced along the Dnipro towards Dudchany but claimed they had been halted by Russian fire and that “everything is under control.”

A continued Ukrainian advance along the Dnipro would threaten to undermine the rest of the Russian front north of the river, raising the risk Russian forces there could be cut off.

The White House National Security Council’s spokesman John Kirby noted Ukraine was making gains in the south on Monday, but caveated that they were “incremental” for the time-being.

The battle for Kherson has major military and symbolic significance for both sides. A retreat from the city would seriously undermine Russia's annexation of one of the four Ukrainian regions declared by Vladimir Putin just days ago -- Kherson is supposed to be the capital of the newly annexed region of the same name.
