Thank you for following all our live updates of the Russia-Ukraine war.

We will be closing this blog and moving to the new page below.

It is 6.30am in Ukraine. Here’s where we stand right now:

• Russian troops have reportedly landed in Kharkiv, Ukraine’s second most populous city, according to the security service of Ukraine. Russian partatroopers reportedly landed at around 3am local time (1am GMT) and engaged in heavy fighting with Ukrainian forces.
• Kyiv and other cities in Ukraine are coming under more bombardment in the early hours of Wednesday morning as the Russian military steps up its offensive and moves forces closer towards the capital.
• Joe Biden’s used his State of the Union address to warn Vladimir Putin that he cannot divide the west and that dictators should “pay a price for their aggression”. He won a standing ovation for his praise of the Ukrainian resistance against what he called Russian “tyranny”.
• Biden also announced that the US is closing American airspace to all Russian flights, “further isolating Russia”.
• Four people have been killed after homes in the city of Zhytomyr west of Kyiv were hit by a cruise missile apparently aimed at a nearby airbase, Anton Gerashchenko, adviser to the interior minister, said on his Telegram channel.
• The southern cities of Kherson and Mariupol are likely now encircled by the Russians, according to the UK Ministry of Defence.
• Thousands of Ukrainians are trying to leave Kyiv, our correspondent in Kyiv reported, as Russia’s defence ministry warned residents to leave as it plans to strike targets in the Ukrainian capital. The UN says more than 680,000 people have already fled the city.
• The IMF and the World Bank have condemned the Russian action in Ukraine and the “horrifying” suffering of people there. The organisations pledged a $3bn package of support for the country.
• Apple has said it will pause all product sales in Russia while Boeing is suspending “major operations” in Moscow, as well as “parts, maintenance, and technical support services for Russian airlines”. Ford and the British carmaker Jaguar Land Rover have also suspended operations, along with Nike.
• Brent crude oil has soared 5.8% to $110.09 a barrel, its highest since 2014. The Russian rouble has fallen again in early trading on Wednesday to hit 109.2 to the dollar.

Governments across Southeast Asia are trying to urgently evacuate their citizens from Ukraine.

A group of 53 Thai nationals are expected to leave Ukraine today, while 23 remain in several cities and have been unable to travel “due to lockdowns and other conditions”, according to the spokesman of Thailand’s ministry of foreign affairs, Tanee Sangrat. As of 1 March, 1,143 Thai nationals had departed the country.

Similar efforts are underway across the region, including in Indonesia, which said on Monday that it had evacuated 31 citizens, according to the Jakarta Post. On Tuesday night, a group of 13 Filipinos, including three students and a baby, arrived in Manila, after travelling from Kyiv to Lviv in Western Ukraine, and then to Poland. Six others were repatriated last month.

Southeast Asian governments’ response to Russia’s invasion of Ukraine has mostly been muted. A statement released by the Association of Southeast Asian Nations did not mention Russia by name, but called on “all relevant parties to exercise maximum restraint”.

However, Singapore made a rare announcement this week that it would impose sanctions on Russia, which it said were prompted by the “unprecedented gravity” of the situation.

Brent crude soared 5.8% on Wednesday to stand at $11i.09 per barrel, its highest since early July 2014, as the rising cost of energy showed no sig of easing.

The rise came despite a global agreement to release 60m barrels of crude reserves to try to rein in price increases.

“We think that there is some room still for oil prices to continue to climb,” said Carlos Casanova, senior Asia economist at UBP in Hong Kong told Reuters.

“So much of it depends upon political factors and making sure that some of the supply coming out of Russia is offset with (not just) more oil from U.S. shale, but also Iran.”

My colleague in the US, Dominic Rushe, has covered Biden’s pledge to go after Russian oligarchs in retaliation for the invasion of Ukraine. This is his write-up:

AFP reports that a Polish charity will take in 2,000 Ukrainian orphans. Read the report here:

Russia president Vladimir Putin has signed a decree to prohibit Russians from leaving the country with more than $10,000 in foreign currency, Russia state media outlet TASS reports.

Citing the decree, the news agency reported:

The export of foreign currency cash and foreign currency instruments over $10,000 calculated based on the official exchange rate set by the Russian Central Bank on the day of export will be banned starting on March 2.”

The move is an attempt to “ensure Russia’s financial stability” according to a statement from the Kremlin press office.

It comes in response to the crippling sanctions western nations have imposed on Russia over its invasion of Ukraine.

Russian troops have reportedly landed in Kharkiv, Ukraine’s second most populous city, according to the Security Service of Ukraine.

Ukrainian authorities said at approximately 3am local time, Russian airborne troops landed and engaged in heavy fighting with Ukrainian forces.

“A Russian landing party landed in Kharkiv,” an alert from Ukraine’s State Special Communications agency read just before 3am.

The agency said the soldiers attacked the military medical clinical centre hospital, adding that a “battle broke out between the invaders and the Ukrainian defenders.”

The city, with a population of about 1.5 million, has been encircled for days and saw at least six people killed when the region’s administrative building on Freedom Square was hit with what was believed to be a missile.

The attack on Freedom Square — Ukraine’s largest plaza, and the nucleus of public life in the city — was seen by many Ukrainians as brazen evidence that the Russian invasion wasn’t just about hitting military targets but also about breaking their spirit.

The bombardment blew out windows and walls of buildings that ring the massive square, which was piled high with debris and dust.

“People are under the ruins. We have pulled out bodies,” said Yevhen Vasylenko, an emergency official.

Zelenskiy pronounced the attack on the square “frank, undisguised terror” and a war crime. “This is state terrorism of the Russian Federation,” he said.

The people of Japan have donated ¥2bn ($17m) to a relief fund for Ukraine, according to the Ukrainian embassy in Tokyo.

The embassy said in a tweet that so far more than 60,000 people had contributed.

The Ukrainian ambassador, Sergiy Korsunsky, thanked the Japanese public at a meeting with Kenta Izumi, who leads Japan’s main opposition party, according to the Kyodo news agency.

The Rakuten e-commerce group, meanwhile, has raised ¥1.4bn for its Ukraine humanitarian fund. Among the donors is Yoshiki, leader of the rock band X Japan, who said he had contributed ¥10m.

Rakuten’s chief executive, Hiroshi “Mickey” Mikitani, donated ¥1 billion to the Ukrainian government at the weekend, describing the “unjustified” Russian invasionas a “challenge to democracy”.

Japan said Wednesday it would temporarily close its embassy in Kyiv as Russia’s invasion of Ukraine escalates.

Exxon Mobil has also said it will exit Russia oil and gas operations that it has valued at more than $4b and halt new investment as a result of Moscow’s invasion of Ukraine.

The decision will see Exxon pull out of managing large oil and gas production facilities on Sakhalin Island in Russia’s Far East, and puts the fate of a proposed multi-billion dollar liquefied natural gas (LNG) facility there in doubt, Reuters reports.

“We deplore Russia’s military action that violates the territorial integrity of Ukraine and endangers its people,” the company said in a statement critical of the intensifying military attacks.

Boeing, one of the world’s largest aerospace manufacturers, has announced it is cutting ties with its Russian partners.

The US airplane maker said it would suspend all major operations in Moscow and will no longer provide technical support or maintenance, or parts, for Russian aircraft.

We have some more confirmed developments regarding Joe Biden’s announcement that the US will ban Russian flights from its airspace.

The US Department of Transportation and Federal Aviation Administration said orders blocking Russian aircraft and airlines from entering and using all US airspace will be fully in effect by the end of Wednesday.

The orders suspend operations of all aircraft owned, certified, operated, registered, chartered, leased, or controlled by, for, or for the benefit of, any Russia citizen.

This includes passenger and cargo flights, and scheduled as well as charter flights that will “effectively closing US air space to all Russian commercial air carriers and other Russian civil aircraft,” the department said.

Biden also delivered a clear message to Russian oligarchs:

Tonight I say to the Russian oligarchs and corrupt leaders who have bilked billions of dollars off this violent regime no more. The US Department of Justice is assembling a dedicated task force to go after the crimes of Russian oligarchs. We are joining with our European allies to find and seize your yachts your luxury apartments your private jets. We are coming for your ill-begotten gains.”

The US president detailed economic sanctions, such as the decision to cut off Russia’s largest banks from the international financial system and “choking off” Russia’s access to technology that will “sap its economic strength and weaken its military” for years to come.

Biden’s State of the Union speech promised an “unwavering resolve” that “freedom will always triumph over tyranny”.

Read some of the key excerpts below:

Six days ago, Russia’s Vladimir Putin sought to shake the foundations of the free world thinking he could make it bend to his menacing ways. But he badly miscalculated.

He thought he could roll into Ukraine and the world would roll over. Instead he met a wall of strength he never imagined.

He met the Ukrainian people.

From President Zelenskiy to every Ukrainian, their fearlessness, their courage, their determination, inspires the world.

Groups of citizens blocking tanks with their bodies. Everyone from students to retirees teachers turned soldiers defending their homeland ...

Throughout our history we’ve learned this lesson when dictators do not pay a price for their aggression they cause more chaos. They keep moving.

Putin’s latest attack on Ukraine was premeditated and unprovoked. He rejected repeated efforts at diplomacy. He thought the west and Nato wouldn’t respond. And he thought he could divide us at home.

Putin was wrong. We were ready. Here is what we did. We prepared extensively and carefully.”

Biden then said the free world will hold the Russian president accountable.

We are inflicting pain on Russia and supporting the people of Ukraine. Putin is now isolated from the world more than ever.

Putin has unleashed violence and chaos. But while he may make gains on the battlefield – he will pay a continuing high price over the long run.

When the history of this era is written Putin’s war on Ukraine will have left Russia weaker and the rest of the world stronger.

In the battle between democracy and autocracy, democracies are rising to the moment, and the world is clearly choosing the side of peace and security.

This is a real test. It’s going to take time. So let us continue to draw inspiration from the iron will of the Ukrainian people.

Putin may circle Kyiv with tanks, but he will never gain the hearts and souls of the Ukrainian people.

He will never extinguish their love of freedom. He will never weaken the resolve of the free world.”

In a moving address, Joe Biden recognised the Ukrainian ambassador to the US, Oksana Markarova, who is also in attendance at the State of the Union this evening.

The Ukrainian Ambassador to the US is here tonight, sitting with the First Lady. Let each of us if you’re able to stand, stand and send an unmistakable signal to the world and Ukraine.”

Markarova then received a robust standing ovation from those assembled in the House chamber.
