This was CNBC's live blog tracking developments on the war in Ukraine. See here for the latest updates.
Russian President Vladimir Putin slammed the West again on Wednesday, saying sanctions imposed on Russia for its invasion of Ukraine are a "danger" to the world.
Speaking at an economic forum in Russia's far east, Putin said Western countries have aggressively tried to impose their way of life on other countries and to make them "submit to their will."
Meanwhile, Ukraine appears to have launched a counterattack in the Kharkiv region in the northeast of the country, with several reports of fighting in the region.

Overnight and early this morning, the head of the Kharkiv regional state administration, Oleg Synegubov, posted on Telegram that Russian forces were shelling various parts of Kharkiv, the second-largest city in Ukraine, and fighting was taking place in the province.
Analysts said Russia's redeployment of troops from eastern to southern Ukraine to defend against Ukraine's counteroffensive there has likely enabled Kyiv to carry out the counterattack around Kharkiv.
U.S. ambassador to U.N. says Russia has deported up to 1.6 million Ukrainians to 'filtration camps'
U.S. Ambassador to the United Nations Linda Thomas-Greenfield said that Russian authorities have forcibly deported between 900,000 and 1.6 million Ukrainian citizens from their homes to Russia.

"We have evidence that hundreds of thousands of Ukrainian citizens – including children – have been interrogated, detained, and forcibly deported, and some of them sent to very remote areas," Thomas-Greenfield told reporters ahead of the U.N. Security Council meeting.
"I want to be clear, the United States has information that officials from Russia's presidential administration are overseeing and coordinating these filtration operations," Thomas-Greenfield said, without naming Russian President Vladimir Putin.
Thomas-Greenfield outlined the "filtration" process for members of the U.N. National Security Council.
"You're stripped of your clothes, you are interrogated, you're beaten. You hear gunfire and screams from rooms next door. Others deemed more threatening are being tortured and killed. Because you are fighting age, you're asked to fight for Russia," she said.
"When you refuse, you're given a Russian passport and set deep into Russia against your will far away from your family and with no means to communicate with anyone you know or love. You've been filtered," she added.
The Kremlin has denied that it has forcibly detained Ukrainian civilians.

Kyslytsya addressed members of the U.N. Security Council.
Grossi, who led a team of investigators to the site earlier this month, published a report yesterday on the nuclear watchdog agency's findings.
Grossi recommended an immediate establishment of a demilitarized zone at the Zaporizhzhia nuclear power plant.

"We will work actively together to persuade others across the globe to support it, especially those who may still have doubts. The fact that our call was Foreign Secretary's first speaks for itself," he added.

Ukrainian official urges residents near Zaporizhzhia nuclear power plant to evacuate
Ukraine's deputy prime minister called on residents near the Zaporizhzhia nuclear power plant to evacuate the area amid reports of Russian troops holding Ukrainians in the area hostage.
"The Russians are holding hostage not only the staff of the station. Residents of the temporarily occupied territories adjacent to the Zaporizhzhia nuclear power plant are also held hostage. Tens of thousands of people," Iryna Vereshchuk wrote on Telegram, according to an NBC News translation.
Vereshchuk added that Ukraine's Ministry of Reintegration requested a humanitarian corridor in order to evacuate the civilian population from areas adjacent to the nuclear power plant.
"The answer is cynical silence," she said.

Putin and Xi to meet next week as war in Ukraine shows no signs of halting
Russian President Vladimir Putin and Chinese President Xi Jinping plan to meet next week in Uzbekistan, a Russian official said Wednesday, announcing a summit that could signal another step in warming ties between two powers that are increasingly facing off against the West.
Putin and Xi last met in Beijing in February, weeks before the Kremlin sent troops into Ukraine.
The two presidents oversaw the signing of an agreement pledging that relations between the sides would have “no limits.”
It remains unclear whether Xi knew at the time of Russia’s plans to invade Ukraine.

More than 7 million Ukrainians have become refugees from Russia's war
More than 7 million Ukrainians have become refugees and moved to neighboring countries since Russia invaded Ukraine in late February, the U.N. Refugee Agency estimates.
Nearly 4 million of those people have applied for temporary resident status in neighboring Western countries, according to data collected by the agency.
"The escalation of conflict in Ukraine has caused civilian casualties and destruction of civilian infrastructure, forcing people to flee their homes seeking safety, protection and assistance," the U.N. Refugee Agency wrote.

Zaporizhzhia nuclear power plant shutdown being considered, official says
Ukraine's top nuclear inspector says the Zaporizhzhia nuclear power plant could be shut down if hostilities continue around the plant. Europe's largest nuclear plant continues to be at the center of accusations between Russia and Ukraine — with both repeatedly accusing each other of shelling the Russian-occupied facility.
The head of Ukraine's nuclear regulatory body, Oleh Korikov, said shutting down the plant was under consideration.
"Further deterioration of the situation will lead to the fact that we will be forced to operate backup diesel power generators in order to sustain our security systems, and diesel fuel reserves are very difficult to replenish in conditions of war," Korikov said Wednesday in an interview broadcast on YouTube.
"In fact, we will need four tanks of diesel per day. It is very problematic to bring such a volume of fuel across the contact line now. That is, we can potentially get into a situation where we run out of diesel, which can lead to an accident with damage to the active zone of the reactors and the release of radioactive products into the environment. Then it will have consequences not only for Ukraine but also for other countries," he said.
"The option of turning off the station is indeed considered if appropriate conditions arise that would require such a stop. If this happens, the 6th power unit will be turned off."
The 6th reactor is currently the only one functioning in the plant, which was inspected by the International Atomic Energy Agency last week.
In the 52-page report, IAEA investigators warned that while ongoing shelling "has not yet triggered a nuclear emergency, it continues to represent a constant threat to nuclear safety and security."
"The IAEA recommends that shelling on site and in its vicinity should be stopped immediately to avoid any further damages to the plant and associated facilities, for the safety of the operating staff and to maintain the physical integrity to support safe and secure operation," wrote IAEA Director General Rafael Grossi.

'Heavy fighting' taking place in north, east and south of Ukraine, UK says
Britain's Ministry of Defense has confirmed earlier reports from officials in Ukraine that the armed forces there have been counterattacking Russian positions in the northeastern and eastern parts of the country, as well the south, where a counteroffensive was launched last week.
"Over the last 24 hours, heavy fighting has taken place on three fronts: in the north, near Kharkiv; in the east in the Donbas; and in the south in Kherson Oblast," the ministry said in its latest intelligence update Wednesday.
"Russia's planned main effort is probably an advance on Bakhmut in the Donbas, but commanders face a dilemma of whether to deploy operational reserves to support this offensive, or to defend against continued Ukrainian advances in the south," the ministry added.
"Multiple concurrent threats spread across 500km will test Russia's ability to coordinate operational design and reallocate resources across multiple groupings of forces. Earlier in the war, Russia's failure to do this was one of the underlying reasons for the military's poor performance," it said.

Russia hints at Putin-Xi meeting in mid-September
Russia has indicated that plans are being made for President Vladimir Putin to meet his Chinese counterpart Xi Jinping on the sidelines of the Shanghai Cooperation Organization summit in Samarkand, Uzbekistan, from Sept.15-16.
Russian envoy to Beijing, Andrey Denisov, told reporters on Wednesday that "in less than ten days we will have a regular meeting of our SCO leaders in Samarkand, we are getting ready for it. In general, this summit promises to be interesting, because it will be the first full-fledged summit since the pandemic," he said in comments reported by Russian state news agency Tass.
"One way or another, there will be plenary sessions and various kinds of group meetings, and we are planning a serious, full-fledged meeting of our leaders with a detailed agenda, which we are now, in fact, working on with our Chinese partners," the official said.
Russia has increasingly looked to China for support as its relations with the West deteriorate, and Beijing has called for a diplomatic resolution to the war.

Putin says sanctions are a "danger" to the world
Russian President Vladimir Putin slammed the West again on Wednesday, saying sanctions imposed on Russia for its invasion of Ukraine are a "danger" to the world.
"The pandemic has been replaced by new challenges of a global nature, carrying a threat to the whole world, I'm talking about the sanctions rush in the West and the West's blatantly aggressive attempts to impose their modus vivendi on other countries, to take away their sovereignty, to submit them to their will," he said, addressing delegates at Russia's Eastern Economic Forum in Vladivostok, a port city on Russia's Pacific coast.
Putin said there's "nothing new" about the West's policy but added that the current situation was precipitated by the United States' "slipping dominance" in global politics and economics.
He added that the West has been reluctant to recognize "irreversible tectonic shifts" in international relations and that the Asia-Pacific region has become a magnet for human resources, capital and production capacities.
"Despite that, the Western countries are trying to maintain the old world order that only benefitted them," he said.

Ukraine has launched a counterattack in Kharkiv, officials suggest
Ukraine has launched a counterattack in the Kharkiv region in the northeast of the country, with several reports of fighting in the town of Balakliia, which lies between the cities of Kharkiv and Izyum.
Overnight and early this morning, the head of the Kharkiv regional state administration, Oleg Synegubov, posted on Telegram that Russian forces were shelling various parts of Kharkiv, the second-largest city in Ukraine, and fighting was taking place in the province.
"Active fighting continues on the contact line. The enemy continues to intensively fire at the positions of our military, the Armed Forces of Ukraine are retaliating. As a result of the successful actions of our defenders, the occupiers from private military companies suffered great losses in the temporarily occupied Oleksandrivka," he said on Telegram.
In its latest military update, Ukraine's armed forces said Russia had launched missile and air strikes on civilian infrastructure "in the areas of Kharkiv" and elsewhere in eastern and southern Ukraine, where the fighting remains most intense between the forces. CNBC was unable to independently verify the reports.
Analysts at the Institute for the Study of War said in an overnight update that "Ukrainian forces have launched likely opportunistic counterattacks in southern Kharkiv Oblast [province] and retaken several settlements."
The analysts noted that Russian redeployments of forces from this area to defend against the Ukrainian counteroffensive in Kherson, southern Ukraine, "likely prompted and facilitated these counterattacks."
Last night, Serhiy Leshchenko, an advisor to President Zelenskyy, tweeted that there would be "great news" from the president regarding the "counteroffensive operation in Kharkiv region." The tweet has since been deleted and Zelenskyy made little reference to the region in his nightly address.
Ukraine has become tight-lipped about its counteroffensive in southern Ukraine in order not to reveal its military strategies and objectives to Russia.

Six NATO allies have yet to ratify Finland and Sweden's entry into the alliance
Six NATO member countries have yet to sign ratification protocols for Finland and Sweden to join the military alliance.
In May, both nations began the formal process of applying to NATO as Russia's war in Ukraine raged. All 30 members of the alliance have to ratify Sweden and Finland into the group.
Greece, Hungary, Portugal, Slovakia, Spain and Turkey are the six of the 30 allies yet to do so.
Last month, U.S. President Joe Biden signed ratification documents following a 95-1 Senate vote to bring Finland and Sweden into NATO.

The Kremlin announces sanctions on Sean Penn, Ben Stiller and U.S. senators
Moscow imposed personal sanctions on American celebrities Sean Penn and Ben Stiller, along with 23 other U.S. cultural figures and several U.S. senators.
"In response to the ever-expanding personal sanctions by the Biden Administration against Russian citizens, a group of persons from members of the U.S. Congress, high-ranking officials, representatives of business and expert communities, as well as cultural figures (25 people), are banned from entry into the Russian Federation on a permanent basis," the Russian Foreign Ministry wrote, according to an NBC News translation.
Penn and Stiller have been outspoken critics of Russia's war and have both visited Ukraine since the Kremlin's military campaign began nearly seven months ago.
U.S. Sens. Mark Kelly, Rick Scott and Kyrsten Sinema were also sanctioned.

Russia is purchasing rockets and artillery from North Korea, U.S. Defense official says
Russia is buying millions of rockets and artillery shells from North Korea, a senior U.S. Defense official confirmed to NBC News.
"This purchase indicates that the Russian military continues to suffer from severe supply shortages in Ukraine, due in part to export controls and sanctions," the official told NBC News, confirming a New York Times report.
"We expect Russia could try to purchase additional North Korean military equipment going forward," the official added.
Last week, the Biden administration confirmed that Moscow purchased drones from Iran to use on the battlefield in Ukraine.

IAEA details damage from shelling, poor work conditions at Zaporizhzhia nuclear site in new report
The International Atomic Energy Agency, or IAEA, released a report on its findings from a recent mission to the Zaporizhzhia nuclear power plant.
In the 52-page report, IAEA investigators warned that while ongoing shelling "has not yet triggered a nuclear emergency, it continues to represent a constant threat to nuclear safety and security."
"The IAEA recommends that shelling on site and in its vicinity should be stopped immediately to avoid any further damages to the plant and associated facilities, for the safety of the operating staff and to maintain the physical integrity to support safe and secure operation," wrote IAEA Director General Rafael Grossi.
The Ukrainian employees working at the site under Russian control were "under unbelievable pressure" and "morale and the emotional state of staff were very low," according to IAEA investigators.
Investigators described significant damage to buildings at the Zaporizhzhia nuclear power plant and confirmed that Russian military vehicles and equipment were seen stored at the site.
