This has been CNBC's live blog covering updates on the war in Ukraine. [Follow the latest updates here.]
The "heaviest of battles" lies ahead in Kherson as Ukrainian troops advance on occupying Russian forces, according to a Ukrainian presidential advisor. While Russia's grip on the strategic territory is shakier than in previous months, it does not appear ready to abandon it. Rather, it appears to be digging in for prolonged fighting after ordering civilians to evacuate and inviting remaining men to local join militias.
Russia has sent a letter to the United Nations pushing its unsubstantiated claim that Ukraine is preparing to use a nuclear-laced "dirty bomb" on its own territory. In a 310-page document, it outlined Ukraine's plan to use bioweapons, allegations vocally rejected and largely debunked by Ukrainian and Western officials and weapons experts.

White House not taking sanctions off the table in response to Iranian arms transfers to Russia
The U.S. is "not taking sanctions off the table" in response to Iranian arms transfers to Russia, National Security Council spokesman John Kirby said.
Kirby declined to detail potential diplomatic or economic actions Washington would take.
Moscow has carried out several devastating missile and drone strikes against what Ukraine said were civilian targets and critical infrastructure such as energy facilities.
Iran and Russia's representatives at the United Nations have sharply denied reports that Tehran supplied Moscow with a fleet of drones for use in Ukraine. The Kremlin has repeatedly denied that it uses Iranian-made drones to target residential and other high civilian areas.

Conversations with Russians for WNBA star Griner's release have not stopped, White House says
U.S. officials are still talking with their Russian counterparts about the release of WNBA star Brittney Griner, National Security Council spokesman John Kirby said.
"The conversations with the Russians continue, they haven't stopped," Kirby told reporters at the White House. He added that the Biden administration is working on the immediate release of former U.S. Marine Paul Whelan.
Whelan was arrested in 2018 on charges of acting as a spy for the United States. At the time he was arrested, Whelan was visiting Russia to attend a wedding, according to his brother, David Whelan.
On Tuesday, a Russian court upheld Griner's nine-year prison sentence, a decision that will send the U.S. athlete to a penal colony.
Griner, who plays professional basketball in Russia during the WNBA offseason, was arrested in February after Russian authorities found vape canisters containing cannabis oil in her luggage at Moscow's Sheremetyevo Airport.

A number of efforts are underway to investigate Russian crimes committed in Ukraine, said Stephane Dujarric, the spokesman for the United Nations secretary-general.

The Kremlin has previously denied that its forces have committed war crimes in Ukraine, including indiscriminate attacks on civilians and critical infrastructure.

Russian state media claims Kyiv has built a dummy rocket to deploy 'dirty bomb'
Russian state media claimed that Ukraine has made a dummy rocket to deploy a "dirty bomb" near the Chornobyl nuclear power plant.
The U.S. and its allies have previously denied Russian allegations that Ukraine is planning to use a "dirty bomb" in order to escalate the conflict.
The report in Russia's RIA Novosti alleges that Ukrainian forces are planning to fill the rocket with radioactive material and blame an explosion on Russian forces.

Blinken says there is a bipartisan support to 'stick with Ukraine'
Secretary of State Antony Blinken said the U.S. and its allies will continue to hold Russia accountable despite some concerns from lawmakers over the mounting financial burden.
"You can't simply go in and seize territory from another country, you can't change the borders of another country by force, you can't try to erase its independence and sovereignty from the map," Blinken said during an event hosted by Bloomberg.
"If we allow that to go unchecked, if we allow them to proceed with impunity, it opens Pandora's box around the world for the would-be aggressors," he added.
Blinked added that in his conversations with "members of Congress, Republicans, Democrats, House and Senate, there's a shared conviction" to stick with Ukraine.

Remains of U.S. citizen killed while fighting for Ukraine 'will soon be returned to the family,' State Department says
Russia returned the body of an American citizen who died fighting for Kyiv to Ukrainian forces, the State Department confirmed.
"Out of respect for the privacy of the family, we will not release further details," State Department spokesman Ned Price said in a statement.
Price reiterated that U.S. citizens should still not travel to Ukraine and urged all Americans currently in the war-weary country to "depart immediately."
"U.S. citizens who travel to Ukraine, including to participate in the fighting there, face significant risks and the United States cannot guarantee their safety," Price added.

At least 10 million people will need psychosocial support from Russia’s war in Ukraine, WHO says
Ukraine's Ministry of Health and the World Health Organization report that at least 10 million people will need psychosocial support due to the trauma from Russia's conflict in Ukraine.

Resident Coordinator in Ukraine, in remarks before the United Nations Security Council.
Brown added that civilians in recently liberated areas of Ukraine are particularly vulnerable as they have "witnessed or experienced terrible violations" committed by Russian forces.

Putin is 'unlikely' to use a nuclear weapon, U.S. Army secretary says
U.S. Secretary of the Army Christine Wormuth said it is unlikely that Russian President Vladimir Putin will deploy a nuclear weapon in his fight with Ukraine, but called the Kremlin's recent rhetoric concerning.
"There is a lot of concern given how Putin has escalated [the conflict]," Wormuth told CNBC's Morgan Brennan when asked about Western fears that Russia could resort to nuclear warfare in its armed conflict with Ukraine.
"Certainly there is a concern," Wormuth said, adding that despite Putin's threats to use such a weapon against its ex-Soviet neighbor, it is "still an unlikely event."
President Joe Biden told reporters yesterday that Russia would be making "an incredibly serious mistake" if Moscow used a tactical nuclear weapon in its fight with Ukraine.
"I'm not guaranteeing that it's a false flag operation," Biden said, referencing Russian allegations that Ukraine is planning to use a "dirty bomb" in order to escalate the conflict.
"It would be a serious serious mistake," Biden added.
The United States and Russia hold the lion's share of the world's nuclear weapons.

Putin observes Russian strategic nuclear forces exercises: state media
Russian President Vladimir Putin on Wednesday observed exercises by Russia's strategic nuclear forces, the Kremlin said.
"The tasks envisaged during the training of the strategic deterrence forces were completed in full, all missiles reached their targets," a Kremlin statement said.
The Zvezda military news channel showed Defense Minister Sergei Shoigu telling Putin that the exercises were practicing "delivering a massive nuclear strike by strategic offensive forces in response to an enemy nuclear strike".
Chief of Staff Valery Gerasimov told Putin the exercise involved Yars intercontinental ballistic missiles, submarines and Tupolev strategic bomber planes.
Russian officials have in recent weeks repeatedly accused Ukraine of planning to use a "dirty bomb" - a bomb laced with radioactive material. They have provided no proof for the allegation.

Putin says the risk of world conflict is 'high', accuses Ukraine of 'dirty bomb' plans
Russian President Vladimir Putin said his government was "aware" of plans by Ukraine to use a "dirty bomb," a claim that's already been made by several Kremlin officials without evidence since the start of the week.
The Russian president, in a meeting with intelligence directors from several ex-Soviet countries, said that the risk of conflict in the world, and in the region, was "high" and that security needed to be increased around its critical infrastructure.
Ukrainian and Western officials as well as weapons experts say that Ukraine does not have the means to build a "dirty bomb," which is a bomb laced with nuclear material deployed to contaminate a large area with radioactivity.
Kyiv has invited the U.N.'s nuclear watchdog agency, the International Atomic Energy Agency, to inspect its nuclear power plants to debunk Russia's allegation, which they say is being spread as a "false flag" operation to escalate the conflict.
Moscow holds that its claim is true and has held high-level calls with defense ministers from NATO countries as well as India and China, and delivered a letter to the U.N., to emphasize it.

Mercedes-Benz becomes latest Western company to leave Russia
Automaker Mercedes-Benz is the latest Western company to leave Russia, one of a handful of major carmakers to withdraw from the country.
The German car company ceased its manufacturing in and exports to Russia in March shortly after Russia's full-scale invasion of Ukraine began. Now, however, it says it will depart from the country's market fully and sell its subsidiaries to local buyers.
Mercedes-Benz Chief Financial Officer Harald Wilhelm said the Russia exit was not predicted to have a major impact on the company's profits.
French carmaker Renault and Japan's Toyota and Nissan all halted their manufacturing operations in Russia in previous months. General Motors, Jaguar Land Rover, Rolls-Royce and Aston Martin also stopped deliveries to the country in the months following the invasion in February.

Kremlin says assets in Russian-annexed regions of Ukraine could be transferred to Russian companies
The Kremlin on Wednesday said that assets in the four Ukrainian regions that Russia said it had annexed last month may in future be transferred to Russian companies.
Kremlin spokesman Dmitry Peskov said it was obvious that "abandoned assets" could not be left inactive, and the government would deal with the issue.
Ukraine, its Western allies and an overwhelming majority of countries at the U.N. General Assembly have condemned Russia's declared annexation of the four regions as illegal.

Russian defense minister reiterates Ukrainian 'dirty bomb' claim to Indian and Chinese counterparts
Russian Defense Minister Sergei Shoigu held calls with his Indian and Chinese counterparts during which he continued to push the Kremlin allegation, without evidence, that Ukraine is planning to use a "dirty bomb" on its own territory. A "dirty bomb" is laced with nuclear material and used to contaminate large areas with radioactivity without an explosion.
Indian Defense Minister Rajnath Singh told Shoigu that nuclear weapons must not be used at all by either side, saying that "the prospect of the usage of nuclear or radiological weapons goes against the basic tenets of humanity," according to an Indian government statement. He also stressed the need for the conflict to be resolved through diplomacy.
The calls followed similar calls from Shoigu to NATO defense ministers.
Ukrainian and Western officials have roundly denounced the Russian claim as "false" and a pretext for escalation, and Kyiv has requested an inspection by the U.N.'s nuclear watchdog, the International Atomic Energy Agency, in order to debunk Russia's accusation.

Moscow official calls for 'de-Satanization' of Ukraine
A member of Russia's security council is calling for a new mission of "de-Satanization" in Ukraine, after months of basing Moscow's invasion on the need to "denazify" the country.
In a letter an article, Russian Security Council assistant secretary Aleksey Pavlov argued that this was increasingly urgent as there are, he claimed, "hundreds of sects" operating in the country.
"I believe that with the continuation of the special military operation, it becomes more and more urgent to carry out the de-Satanization of Ukraine, or, as the head of the Chechen Republic Ramzan Kadyrov aptly put it, its 'complete de-Satanization'," he said.
Pavlov claimed that the "Church of Satan... spread across Ukraine," adding that it is "one of the religions officially registered in the United States."
"All this Satanism finds a lively response and support from the official Ukrainian authorities," he added, without citing evidence.

Russian forces are regrouping and gathering strength in Kherson, Kyiv official says
Russian forces show no sign of abandoning Kherson despite the growing Ukrainian counteroffensive to retake the territory that Russia has occupied since early spring.
While Russian-imposed authorities in the region have ordered civilians to evacuate, "the Russians are replenishing, strengthening their grouping there," Ukrainian President advisor Oleksiy Arestovych said.
"It means that nobody is preparing to withdraw. On the contrary, the heaviest of battles is going to take place for Kherson."
Kherson is the largest Ukrainian city under Russian control, and lies in the strategic south-east area that Moscow wants as a land bridge to Crimea, which it annexed in 2014. Kherson is one of four major regions in Ukraine's south and east that Russia declared as annexed — illegal under international law — in late September.

Infrastructure bottlenecks hamper Russia's booming coal exports to China: Reuters
Russian coal exports to energy-hungry China have jumped by about a third this year but the supply boom is being constrained by transport infrastructure limitations, industry sources and officials said.
China is seeking coal supplies from overseas, in particular after recent Covid-19 outbreaks in the major coal mining regions of Inner Mongolia and Shaanxi forced many mines to close, while coal demand at power generation and heating sectors will soon pick up with the coming of winter.
The Kremlin plans to increase its energy supplies to Asia, China in particular, to offset a slump in exports to the West, which has imposed sanctions on Russia over the conflict in Ukraine.
Russia is the world's sixth-largest coal producer and one of top coal exporters, along with Indonesia and Australia. Its share of global coal exports reached 17% last year with supply of 223 million tons.

Ukrainian official asks Ukrainians abroad to not return home and to stay abroad
Ukraine's deputy prime minister Iryna Vereshchuk asked Ukrainians who are currently abroad to not return home yet, according to an NBC News translation.
"I will ask you not to return, we have to survive the winter," Vereshchuk said, adding that Ukraine's energy sector and infrastructure is too weak from the war to provide adequate support.
"If there is an opportunity to stay, for the time being, spend the winter abroad," she added.
In recent weeks, Russian missiles and drone strikes have targeted critical Ukrainian infrastructure like energy systems. The Kremlin has previously denied Ukrainian and Western claims that it targets civilian infrastructure, which is a violation of the laws of conflict.

White House says it would be a 'major mistake' for Russia to use nuclear weapons
White House Press Secretary Karine Jean-Pierre said it would be "a major mistake" for Russia to use nuclear weapons in Ukraine and that it is taking the threat of a dirty bomb seriously.
"It would be a major mistake for Russia to use nuclear weapons in Ukraine leading to severe consequences," Jean-Pierre said at the daily briefing.
The statement came in response to a question about the potential for Russia to use a dirty bomb. Russia has accused Ukraine of planning to use a "dirty bomb" on its own territory. On Tuesday Russia reiterated the allegations in a letter to the United Nations Security Council.
"We must take this seriously because in the past we have seen Russia use allegations as a pretext to escalate."
