This is CNBC's live blog tracking developments on the war in Ukraine. See below for the latest updates.
Ukraine's Western allies on Friday convened at the Ramstein Air Base in Germany to discuss further assistance to Kyiv, in the 14th month of Russia's full-scale invasion of Ukraine. Speaking ahead of the meeting, NATO Secretary-General Jens Stoltenberg, who unexpectedly undertook his first visit to Ukraine since Russia began its offensive in February last year, reaffirmed that Kyiv will eventually join the military alliance.
Once the war in Ukraine ends, Kyiv must have "the deterrence to prevent new attacks," he said in comments reported by Reuters.
Ukrainian President Volodymyr Zelenskyy on Thursday reiterated his long-standing call that his country should benefit from fast-tracked admission into NATO.
"There is not a single objective barrier to the political decision to invite Ukraine into the alliance and now, when most people in NATO countries and the majority of Ukrainians support NATO accession, is the time for the corresponding decisions," he said at the time.
NATO and EU allies have so far offered military, humanitarian and financial aid to Ukraine. Analysts warn that Kyiv's fast-track bid for NATO membership, launched in September last year, could elude or take years to gain approval, as allies stay wary of further antagonizing Russia.

"I saw clear indications of military preparations in the area when I visited the Zaporizhzhia nuclear power plant just over three weeks ago," IAEA director general Rafael Grossi said in a statement.
"Since then, our experts at the site have frequently reported about hearing detonations, at times suggesting intense shelling not far from the site. I'm deeply concerned about the situation at the plant," he added.
Russian forces seized Zaporizhzhia nuclear power plant, Europe's largest, in the days following the Kremlin's full-scale invasion of Ukraine.

Sanctions against Russia could lead to a new global economic crisis, Kremlin says
The Kremlin warned that new Western sanctions imposed on Russia would have a devastating impact on the global economy, and start a new crisis.
"The new additional steps that Brussels and Washington are probably thinking about now, they will, of course, hit the global economy," Kremlin spokesman Dmitry Peskov told reporters during a daily briefing.
"Therefore, this can only lead to an increase in trends towards a global economic crisis," he said, adding that Moscow was "monitoring this very carefully."
Peskov said that no nation in the world has faced the cadence and volume of sanctions as Russia.

Lavrov heads to New York to hold meetings at the United Nations
Russian Foreign Minister Sergey Lavrov will take the helm of the United Nations Security Council on Monday as the Kremlin's war in Ukraine appears to have no end in sight.
The presidency of the Security Council rotates every month among its member nations.
Russia last held the presidency of the Security Council, the U.N. arm dedicated to preserving peace, last February when Moscow launched its full scale invasion of Ukraine. Russia is also a permanent member of the Security Council and holds veto authority of any measure put before the international forum.
Lavrov is expected to hold several meetings before the Security Council and will meet separately with U.N. Secretary General António Guterres while in New York.

Three ships leave Ukrainian ports under Black Sea Grain Initiative
Three ships left Ukraine ports under the Black Sea Grain Initiative, a deal brokered in July between Ukraine, Russia, Turkey and the United Nations.
One ship departed the port of Chornomorsk, carrying 58,134 metric tons of corn to Germany. The other two ships set sail from Odesa, carrying 31,544 metric tons of corn and wheat destined for Spain.
A day prior, no ships left Ukraine's ports.
The humanitarian sea corridor eased Russia's naval blockade and reopened three key Ukrainian ports. Ukraine and the U.N. pushed for a 120-day extension of the deal in March, but Russia has said it may only acknowledge the extension for 60 days.

Russia's Lavrov slams Western sanctions during tour through Latin America
Russian Foreign Minister Sergey Lavrov slammed U.S. sanctions during a visit to Cuba, the last stop on a tour of Latin America.
Russia is one of Havana's few suppliers of oil, a lifeline the island nation has counted on amid decades of severe U.S. sanctions.
Lavrov called for like-minded countries to "join forces" in order to counter "illegal unilateral pressure" by the West. Before Cuba, Lavrov met with counterparts in Brazil, Nicaragua and Venezuela.
In the weeks following Moscow's full-scale invasion of Ukraine, the U.S. alongside Western allies coordinated punishing rounds of sanctions that launched Russia as the most sanctioned country in the world.

Severe mud likely slowing both sides of Ukraine conflict, British Ministry of Defence says
"Severe" mud arising from soft ground conditions across most of Ukraine is "highly likely slowing operations for both sides of the conflict," the U.K. Ministry of Defence signaled in its daily intelligence update on Ukraine for April 21.
Ukraine's muddy season of "rasputitsa," which sets in late fall and early spring, has historically played a role in commanding the pace of regional military campaigns, surprising several invading armies.
The U.K. defense ministry expects surface conditions to improve over the coming weeks and stressed that Russian online outlets are likely exaggerating the mud impact on Ukrainian forces.
"The threat from mines probably continues to be a more important factor in limiting the combatants' off-road manoeuvre," it said.

Kremlin says it is monitoring reports of G-7 ban on exports to Russia
Russia is monitoring reports of a potential ban of Russia-bound exports from Western countries, warning that current and further sanctions will injure the world economy.
"We are carefully monitoring this, we are aware that both the U.S. and the EU are actively considering new sanctions," Kremlin spokesperson Dmitry Peskov said in comments reported by Reuters, adding that such measures will "of course, also hit the global economy" and "may lead to an increase in the trend towards a worldwide economic crisis."
Earlier, Japanese news agency Kyodo reported that the Group of Seven countries were considering a ban on nearly all exports to Russia, citing a Japanese government source. CNBC has not been able to independently verify the report.

Canada announces $29 million package for Ukraine
The Canadian government on Friday announced a 39 million Canadian dollar ($28.9 million) package for Ukraine, which will include 40 sniper rifles, radio sets and a donation to a NATO fund in support of Kyiv.
The lion's share of the contribution — CA$34.6 million — will be directed toward the Ukraine Comprehensive Assistance Package Trust Fund.
"We will continue to stand shoulder to shoulder with Ukraine in the short and the long term," Canadian Defense Minister Anita Anand pledged on Friday, revealing the additional assistance measures.
"All eight Leopard 2 main battle tanks committed by Canada to Ukraine have been delivered, and we've deployed Leopard Gunnery Skills Trainers to train Ukrainian crews," she added.
Anand has arrived at the Ramstein Air Base in Germany, where Ukraine's Western allies will attend a meeting to discuss coordinated action in Ukraine.
NATO chief reassures Ukraine will eventually join the military alliance
NATO members have agreed that Ukraine will join the military alliance, but the current focus is on Kyiv prevailing in the war against Russia and preventing new attacks, NATO Secretary-General Jens Stoltenberg said Friday, in comments reported by Reuters.
Stoltenberg paid an unexpected visit to Kyiv — his first since Russia's full-scale invasion of Ukraine — on April 20.
Ukrainian President Volodymyr Zelenskyy has repeatedly pushed for fast-tracked NATO membership, in addition to weapons support from the military allies. Ukraine's Western allies will on Friday convene at the Ramstein Air Base in Germany to coordinate further assistance to Kyiv.

Russia accidentally strikes own city of Belgorod
A Russian warplane accidentally released a weapon on the Russian city of Belgorod, north of the border of Ukraine, damaging buildings and leading to explosions, the Russian ministry of defense told state news agency Tass.
Russia's defense ministry did not specify what kind of weapon had been unleashed, but identified the plane as a Sukhoi Su-34 fighter — a medium-range supersonic bomber.
Belgorod regional Governor Vyacheslav Gladkov late on Thursday said on Telegram that three people were injured following local explosions, with no dead reported. He announced a state of emergency at Belgorod, where he said a crater with a radius of 20 meters has formed across a main street.

Russian party proposes additional tax on Russia's wealthiest to support war effort
Members of a Russian political party have put forward a proposal to increase the income tax rate of Russia's wealthier citizens with a personal income of more than 12 million rubles ( $147,000 ) by 2% and route this additional funding to support Russia's military offensive in Ukraine, Russia state news agency Tass reported.
The money emerging from additional taxes will be directed to support both mobilized soldiers and their families, the measure proposes.
Russian hydrocarbon-reliant revenues have been increasingly stifled by Western sanctions on its seaborne exports and crude oil and oil products, which have been in place since December and February, respectively.
Drawing from data from the World Bank, the International Monetary Fund and the Organization for Economic Cooperation and Development, the European Council says that Russia's GDP shed 2.1% in 2022.

It's time for NATO to invite Ukraine into the alliance, Zelenskyy says
Ukraine's President Volodymyr Zelenskyy said Thursday that it was time for NATO to invite Ukraine to join the Western military alliance, repeating a much-heard plea from Kyiv for fast-track membership.
Speaking at a joint news conference in Kyiv with NATO Secretary-General Jens Stoltenberg, who made an unannounced visit to Kyiv Thursday, Zelenskyy said he had been invited to the next NATO summit in July, but that Kyiv wanted more.
"I am grateful for the invitation to visit the summit, but it is also important for Ukraine to receive the corresponding invitation," he told reporters in comments reported by Reuters.
"There is not a single objective barrier to the political decision to invite Ukraine into the alliance and now, when most people in NATO countries and the majority of Ukrainians support NATO accession, is the time for the corresponding decisions."
Stoltenberg said that Ukraine's NATO membership bid — which it launched last September — and security guarantees would be high on the agenda at the alliance's July summit, adding that Ukraine's rightful place was in NATO.
Despite Stoltenberg's words of support and encouragement, analysts believe Ukraine's NATO membership bid faces significant hurdles and could take years to be approved, if it is at all.
Aside from the active war that's ongoing in Ukraine, NATO members such as Hungary and Turkey would likely be very reluctant to further antagonize Russia by admitting Ukraine into the alliance. One of Moscow's key bugbears ahead of the war was a potential further expansion of NATO eastwards to include Ukraine, despite that prospect being, even at that time, a distant possibility.
