Almost 2 years in, here's where Russia's invasion of Ukraine stands

Nearly two years into the war, Russia on Friday launched its "most massive aerial attack"on Ukraine.

Ukrainian officialssaidRussia launched 122 missiles and 36 drones against Ukrainian targets,killing at least 30 civilians and injuring more than 140.

Damage was reported in the capital Kyiv,the central city of Dnipro, the western city of Lviv, the southeastern port of Odesa andthe eastern city of Kharkiv.

The 18-hour barrage brought the war back into focus for many, including CBC readers who want to know where the conflict stands.

Here's a look at some key areas.

Front line

Fighting along the front line is largely bogged down by winter weather after Ukraine's summer counteroffensive failed to make a significant breakthrough along the roughly 1,000-kilometreline of contact and alter the momentum of the war.

Gen. Valeriy Zaluzhnyi, commander in chief of the Ukrainian Armed Forces, penned a frank assessment of the battlefield conditions for theEconomistlast fall thatsuggested the war was sliding toward a stalemate.

In May, Russian forces took Bakhmut, a city in Ukraine's eastern Donbas region, after months of brutal urban combat and heavy causalities on both sides.

The toll on the Russian side was so severe that it prompted a mutiny by the Wagner private military company, which eventually led to a short-lived march on Moscow and later the death of Wagner's leader,Yevgeny Prigozhin.

Though the strategic value ofBakhmutis debated, it held much symbolic value for Ukraine as an example of the country's resistance to the invasion and served as Russia's biggest military gain since the early days of the war.

Much of the focus since has been in nearby Avdiivka, about 90 kilometres south of Bakhmut.As of Dec.21, Russian forces advanced to within two kilometres of the city at an estimated cost of nearly 20,000 casualties.

Avdiivka is seen as a gateway to Donetsk city, an occupied city about 15 kilometres southwhose residential areas Russian officials say have been regularly shelled by Ukrainian forces. Pushing Ukrainian forces out of Avdiivka would be seen by Russia as enlarging the amount of territory itcontrols, while alsomaking Donetsk city safer.

Why Ukraines counteroffensive has stalled

Six months into Ukraines much-anticipated counteroffensive against Russia, experts say the campaign has largely stalled. CBCs Briar Stewart breaks down whats gone wrong and what might happen next.

There have been some Ukrainian gains the past year.

By the end of the summer and after ferocious battles, Ukrainian forces liberatedroughly 65 square kilometres of territory in the central Zaporizhzhia region, though it was a tiny fraction of what Kyiv had initially wanted.

And slowly but surely,war-watchers from both sidesconfirmed that Kyivhas managed to establish a bridgehead on the left bank of the Dnipro River near the village of Krynky, in the central Kherson region.

The territorial gains at theDniproappear small a few square kilometres, at best, and the Ukrainian forces have yet to break out beyond the vicinity of the riverbut the strategic significance may nonetheless be important.

It opens up an avenue for Ukraine to possibly advance toward the southern Crimea peninsula which Russia illegally annexed from Ukraine in 2014 and cut off a land corridor stretching from occupied regions in the east, thereby disrupting supply lines.

In Russia, groups of anti-Kremlin fighters claimed responsibility for attacksin the western Belgorod region that borders Ukraine. Meanwhile,drones have struck buildings in Moscow.

Military goals

Russian President Vladimir Putinsaid the initial invasion of Feb. 24, 2022,which Moscow calls a "special military operation," was to demilitarize and "denazify"Ukraine, citing alleged neo-Nazi elements in Ukraine's government claims derided by Kyiv and the West and the country's ambitions to join NATO.

After failing to take Kyiv, Russia shiftedto capturing the Donbas, a mostly-Russian speaking industrial region in the east.

"There will be peace when we will achieve our goals," Putin said in a rare news conference in mid-December, repeating a frequent Kremlin line.

Ukrainian President Volodymyr Zelenskyyhas long shot down the idea that Ukraine should cede any territory to achieve a ceasefire, andhas said that peace negotiations can only proceed after Russia has fully withdrawn from Ukraine, including Crimea.

Russia rejects the proposal, andPutin has previously said he is ready enter peace talkswith Ukraine, but on Russia's terms.

U.S. officials have said they think he is waiting for the 2024 U.S. presidential election before making any serious moves towardpeace.

Foreign aid

In advance of this summer's expected counteroffensive, European nations and the U.S. provided Ukraine with approximately 100 Leopard 2 main battle tanks,several hundred armoured personnel carriers and other fighting vehicles, and hundreds of thousands of rounds ofartillery ammunition.

After the counteroffensive failed to pull off similar results to what Ukraine achieved in2022, Western support appears to be fracturing financially if not publicly.

In the U.S., more than $60 billion USworth of military aid is stalled in the Senate by Republicans who say that any more money for Ukraine must be passed alongside changes to domestic immigration policy a contentious issue in Washington.

Ukrainian President Zelenskyy appeals to U.S. Congress for more aid

At an in-person visit with U.S. President Joe Biden in Washington, Ukrainian President Volodymyr Zelenskyy made an impassioned plea to Congress for more aid, but skeptical Republicans appear unmoved.

Another huge financial package worth more than $53 billion from the European Union may be boycotted by Hungary's Russia-friendly government.

Zelenskyyhas flown around the world to meet the leaders of Ukraine's allies to stir up support including to Canada, which ended in controversy when Parliament gave a standing ovation to a Ukrainian solider who fought for the Nazis.

While Canada, the U.S. and others say they will continue to back Ukraine, aid commitments havebeen modest compared to contributions from earlier in the war.

For example, the U.S.announced a $250 million US aid package on Wednesday, which President Joe Biden says is the last Washington can send without congressional approval.

Putin said in his December news conference thatKyiv was sacrificing its troops in order to show some success to its Western sponsors as it seeks more aid, which he predicts will dry up soon.

Death tolls and injury counts rise

The U.K. Ministry of Defence said earlier in the month thatbetween late February 2022and November 2023, official Russian forces suffered as many 240,000 wounded and 50,000 killed. Wagner mercenaries likely suffered 40,000 wounded and 20,000 killed, the ministry said.

On the Ukrainian side, a Ukrainian civic group said it has confirmed 24,500 combat and non-combat deaths using open sources. But if many of the 15,000 troops listed as missing are also dead, the figure could be much higher, according to a report published in the Ukrainian journal Tyzhden.

The United Nations has saidmore than 10,000 civilians have been killed andmore than six million have been displaced.
