LIVE UPDATES

This is CNBC’s live blog tracking developments on the war in Ukraine. See below for the latest updates. 

Air raid sirens are sounding out across multiple regions in Ukraine again on Tuesday with the emergency services warning of more Russian strikes, a day after a series of Russian attacks left at least 19 people dead and over a hundred injured.

Ukrainian officials reported that energy infrastructure in the western city of Lviv had been hit earlier, while the city of Zaporizhzhia in the south was also targeted this morning.

Ukrainian President Volodymyr Zelenskyy said in his nightly address Monday that Ukraine will not be intimidated by the strikes that took place Monday and which targeted various regions including the capital Kyiv. Urgent work was being done to repair and restore power supplies damaged during the strikes, he added.

The multiple attacks by Russia came several days after a blast partially destroyed the Kerch Bridge that links the Russian mainland to Crimea, which Moscow illegally annexed in 2014.

Kyiv has not said whether it was responsible for the attack on the bridge, although the blast was widely seen as humiliating for Moscow and President Vladimir Putin.

Putin orders 'revenge' missile strike on Ukraine capital Kyiv after bridge explosion

The leaders of the Group of Seven of the world’s most developed economies are holding an emergency meeting Tuesday to discuss Russia’s war in Ukraine. Addressing the meeting via videolink, Zelenskyy asked for more air defense weapons.

Top officials in the United States, European Union and at the United Nations expressed shock and horror Monday over the strikes. U.N. Secretary-General Antonio Guterres was “shocked” by the attacks, saying through a spokesperson that they represented an escalation of the war.

The strikes have damaged significant parts of Ukraine’s energy grid, prompting the nation’s energy ministry to announce it would halt exports of electricity to the EU starting Tuesday.

Russia adds U.S. tech giant Meta to its banned list, blocking Facebook and Instagram use in the country

Russia’s financial monitoring agency, Rosfinmonitoring, added U.S. tech giant Meta to its list of “terrorists and extremists,” Interfax news agency reported.

A Russian court banned Meta and its activities in Russia, including Facebook and Instagram.

The court’s decision does not prohibit the activities of WhatsApp messenger, which is also owned by Meta, because it does not publicly disseminate information.

Meta considered the decision unreasonable and challenged it, but it was unsuccessful.

Zelenskyy asks G-7 leaders for more air defense weapons

Ukrainian President Volodymyr Zelenskyy addressed U.S. President Joe Biden and other G-7 leaders as they met virtually on Tuesday, asking the group to urgently provide Ukraine with more air defense weapons, Reuters reported.

Kyiv was widely expected to seek additional air defense weapons during the emergency meeting after Moscow ramped-up its missile strikes on various locations across Ukraine on Monday and Tuesday.

The attacks were unleashed after an explosion last weekend partially destroyed Russia’s prized Kerch Strait bridge linking the mainland and Crimea, which Moscow annexed in 2014.

G-7 leaders are also expected to discuss the global energy crisis and how to implement an international cap on the Russian oil price.

Russia dismissed the G-7 meeting with Kremlin spokesman Dmitry Peskov saying the mood of the G-7’s emergency meeting was “obvious and predictable.” “The confrontation will continue,” Peskov said.

Russia lashes out at Ukraine, but it’s ill-equipped to continue the war

Russia has dramatically ramped up its missile attacks on Ukraine in the last 48 hours, but experts say the country is running out of options — as well as supplies and munitions — on the battlefield.

Air raid sirens were once again sounding out across multiple regions in Ukraine Tuesday, with emergency services warning that more Russian strikes were highly likely. Ukrainian officials reported that energy infrastructure in the western city of Lviv had been hit earlier, while the city of Zaporizhzhia in the south was also targeted this morning.

The latest strikes come a day after a series of Russian attacks — launched in response to the bombing last weekend of Russia’s prized Kerch Strait bridge to Crimea — hit various Ukrainian cities, including the capital Kyiv. The strikes left at least 19 people dead and over a hundred injured, the emergency services said.

Despite Moscow’s recent show of strength in the last day or so, experts say Russia’s forces are looking increasingly desperate and ill-equipped.

Russia continues to pound Ukraine’s energy infrastructure

Parts of Ukraine are still struggling with power outages as Russia says it is continuing to target energy infrastructure across the country.

President Zelenskyy said overnight that several hundred settlements remained without electricity after missile attacks yesterday and that authorities had made it a priority to restore power. Officials in Lviv, a major city in the west of Ukraine, reported more power outages Tuesday after Russian missiles targeted the city and wider region’s energy infrastructure.

“Missile attack on a critical infrastructure facility in Lviv. Part of the city is again blacked out,” Lviv Mayor Andriy Sadovyi said on the Telegram messenger app.

Ukrainian Foreign Minister Kulebahas said such attacks were “creating unbearable conditions for civilians.”

Russia openly admits targeting such facilities.

On Tuesday, the country’s defense ministry issued a military update on Telegram stating that its forces continue to launch “massive” attacks “using high-precision long-range air and sea-based armament at the facilities of military control and energy system of Ukraine.”

Top Russian official warns of the ‘danger of uncontrolled escalation’ in the war

A top Russian official warned of the danger of “uncontrolled escalation” if the West continues to support Ukraine, marking the latest threat to be issued by Moscow to Kyiv’s international allies.

Deputy Foreign Minister Sergei Ryabkov said Russia “will be forced to take adequate countermeasures, including of an asymmetric nature,” Ryabkov told Russian state-owned news agency RIA Novosti Tuesday, without detailing what those measures could be.

He said Moscow regretted “the ongoing large-scale assistance to Kyiv” from the West and said that while “a direct clash with the United States and NATO is not in Russia’s interests” there was a hope in Moscow “that Washington and other Western capitals are aware of the danger of uncontrolled escalation.”

Ryabkov’s comments are just the latest instance in a long line of saber-rattling by officials in Moscow, including President Putin, who has threatened to use nuclear weapons if the West continues to support Ukraine in the war, or if Russia deems there to be an existential threat to its territory.

Russia is running out of supplies and munitions, UK intelligence chief will say

The director of GCHQ, one of Britain’s top intelligence agencies, will say in an address today that Russia is running out of supplies and munitions while their forces are exhausted as Ukraine turns tide in the conflict.

GCHQ’s chief Jeremy Fleming is due to speak at the annual RUSI lecture in London on Tuesday afternoon. While his speech will largely focus on China and its impact on global security, he will touch upon the war in Ukraine and is expected to say:

“We know – and Russian commanders on the ground know – that their supplies and munitions are running out,” Fleming will say, according to pre-released comments sent to CNBC by the intelligence, cyber and security agency.

“Russia’s forces are exhausted. The use of prisoners to reinforce, and now the mobilisation of tens of thousands of inexperienced conscripts, speaks of a desperate situation,” he will say, adding that the Russian population is beginning to understand the reality surrounding the war. 

“They’re seeing just how badly Putin has misjudged the situation. They’re fleeing the draft, realising they can no longer travel. They know their access to modern technologies and external influences will be drastically restricted. And they are feeling the extent of the dreadful human cost of his war of choice.”

Fleming is expected to say that far from “the inevitable Russian military victory that their propaganda machine spouted,” it’s becoming clear that Ukraine’s bravery on the battlefield and in cyberspace, counteracting Russian propaganda, is “turning the tide” in the war.

In the meantime, Russian President Vladimir Putin’s decision-making is looking increasingly flawed with “a high stakes strategy … leading to strategic errors in judgement.”

“Their gains are being reversed.  The costs to Russia – in people and equipment are staggering,” Fleming is set to say.

Using nuclear weapons against Ukraine will ‘cement’ Putin as a pariah, says former ambassador

Putin is desperate as he's losing on the battlefield, says former diplomat

The chances of Russian President Vladimir Putin deploying nuclear weapons against Ukraine is low, and would isolate him globally as a pariah, former U.S. ambassador to Ukraine William Taylor told CNBC.

“If President Putin were to use nuclear weapons against a nuclear disarmed Ukraine, this would turn the world against him,” said Taylor.

Taylor said he believes that China and India, along with the rest of the world, would “draw back in horror” if Russia were to resort to nuclear arms.

“This would, I think, further cement President Putin as a pariah. I think there’s no military reason to do it. There’s a lot of political reasons that he shouldn’t do it.”

When asked if there are any traction towards peace talks, Taylor said he does not reckon so, mainly because “the Russians are not at all interested.” There are also no indications that Putin is too committed to the invasion, he added.

Air raid sirens ring out across Ukraine, warning of more Russian strikes

Ukraine’s emergency services warned citizens of the likelihood of more Russian attacks on Tuesday, with air raid sirens ringing out across multiple regions.

The emergency services issued a warning on Telegram Tuesday. “Warning. During the day there’s a high probability of missile strikes on the territory of Ukraine. Please remain in shelters for your own safety, do not ignore air raid signals,” the services said, according to Reuters.

The warning came as the emergency services said that the death toll from Monday’s mass shelling had reached 19, with 105 now known to be injured in the strikes across the country.

This map shows the breadth and duration of air raid alerts on Tuesday, with the capital Kyiv and other major cities including Lviv and Dnipro experiencing more warnings this morning.

Death toll from Russian missile strikes rises

Ukraine’s emergency services said the death toll has risen after Russia’s mass shelling across the country on Monday.

The latest information from the services found that 19 people were killed in the strikes across Ukraine, and 105 were injured.

The services said on Telegram on Tuesday that, as a result of shelling, objects of critical and civil infrastructure were hit in the capital Kyiv as well as 12 other regions. More than 30 fires, caused by the strikes, had to be extinguished by the emergency services.

The power supply has been restored to 3,571 settlements in the Poltava, Sumy, Ternopil, Lviv, Kyiv and Khmelnytskyi regions, although over 300 settlements in those regions still have no electricity.

The emergency services said it had involved 22 power stations to provide power to health-care facilities in the Dnipropetrovsk, Zaporizhzhia, Sumy, Kharkiv, and Chernihiv regions, as well as seven power plants for critical infrastructure facilities.

“More than 1,000 people and about 120 units of emergency services equipment were involved in extinguishing fires and emergency rescue operations,” the services said.

Zaporizhzhia city hit by more Russian strikes

The city of Zaporizhzhia in southern Ukraine has been hit by more Russian strikes on Tuesday morning, officials say.

“As a result of the morning rocket attack, an educational institution, a medical institution and residential buildings were also damaged,” Anatolii Kurtev, the secretary to the Zaporizhzhia city council, said on Telegram, adding that “unfortunately, there are casualties,” without providing more details.

Oleksandr Starukh, the head of the Zaporizhzhia Regional Military Administration, said on Telegram that “several powerful explosions” had rocked the city and that Russian forces “attacked the regional center with missiles. The enemy targeted infrastructure facilities.”

Information on damage and victims was being clarified, he said. CNBC was unable to independently verify the information.

The city was targeted on Monday as Russia conducted missile strikes across Ukraine. The image below shows destruction to a residential building following a missile attack.

Ukraine will not be intimidated by strikes, president says

Ukrainian President Volodymyr Zelenskyy said in his nightly address Monday that Ukraine will not be intimidated by multiple strikes across the country on Monday and that it would respond on the battlefield, vowing to make it “more painful” for Russian forces.

“Ukraine cannot be intimidated. We united even more instead. Ukraine cannot be stopped. We are convinced even more that terrorists must be neutralized. Now the occupiers are not capable of opposing us on the battlefield already, that is why they resort to this terror,” he said.

He said that urgent work was being done to repair and restore damaged infrastructure and power supplies that had been lost during the strikes.

“Restoration work is currently underway across the country. We will restore all objects that were damaged by today’s attack by Russian terrorists. It’s only a matter of time,” he commented on Telegram as well as in a video address from the streets of Kyiv, where a variety of locations were hit, including a playground, cultural centers and office and residential buildings. 

Zelenskyy said that out of 84 Russian missiles launched against Ukraine, 43 had been shot down on Monday, and out of 24 Russian drones, 13 were shot down.

The president called on Ukrainians to restrict their power use between certain hours to relieve pressure on the energy system.

Zelenskyy will address G7 after Russian missiles rock Ukrainian cities

Ukrainian President Volodymyr Zelenskyy will address a virtual emergency G7 leaders meeting on Tuesday after Russian missile strikes rocked Ukrainian cities.

Since Russia’s late-February invasion of Ukraine, the G7 has imposed a slew of coordinated sanctions against Moscow. The group kicked Russia out of the G8 following its illegal annexation of Crimea in 2014.

The G7 leaders on Tuesday are also expected to discuss the mounting global energy crisis and ways to implement an international cap on the price of Russian oil.

The emergency meeting of the G7 follows a series of deadly missile strikes across Ukraine, killing at least 14 people and wounding 97.

Putin confirms he ordered attack on Ukrainian cities; vows ‘harsh’ response to ‘terrorist’ acts

Russian President Vladimir Putin confirmed that he ordered long-range missile strikes on a number of locations in Ukraine targeting military, energy and communications facilities.

“If attacks continue against Russia, the response will be harsh. The responses will be of the same scale as the threats to Russia,” Putin said during a meeting of his national security council.

“In the event of further attempts to carry out terrorist acts on our territory, Russia’s response will be harsh.”

Putin did not mention that the missile strikes hit several civilian areas and resulted in numerous casualties. The EU has said Russia’s indiscriminate attacks on civilians in Ukraine constitute a war crime.

Putin has blamed Ukraine for the explosion on Russia’s Kerch bridge Saturday morning — the only bridge connecting the country to Crimea, which it illegally annexed from Ukraine in 2014 — and called it a terrorist attack. Kyiv has not claimed responsibility for the blast that destroyed part of the bridge.

Multiple cities across Ukraine hit by missile attacks

Several Ukrainian cities have been hit by what officials are describing as a wave of missile attacks — as far west as the city of Lviv, largely considered one of the safest parts of the country.

Kyiv, Dnipro, Zaporizhzhia, Lviv and Vinnytsia, among other cities, have all reported explosions.

“Kyiv region and Khmelnytsky region, Lviv and Dnipro, Vinnytsia, Frankiv region, Zaporizhzhia, Sumy region, Kharkiv region, Zhytormyr region, Kirovohrad region, the south,” Ukrainian President Volodymyr Zelenskyy wrote on Telegram. He described Russian President Vladimir Putin as a “terrorist” targeting civilians.

At least 8 people in Kyiv have been killed and two dozen injured, according to the city’s emergency services.
