The Russian invasion of Ukraine entered its third week on Thursday, with Russian forces continuing to bombard major cities.

Satellite photos show that a massive Russian convoy that had been mired outside the Ukrainian capital since last week has fanned out into towns and forests, with artillery pieces moved into firing positions.

Thousands of people have been killed and more than 2.3 million have fled the country since Russian troops crossed into Ukraine on Feb. 24. Besieged cities have been suffering from shortages of food, medicine, heat and electricity.

Here are some key things to know about the war:


Russia continued its heavy bombardment of Mariupol on Thursday, hitting the fire department's headquarters, a university building and other structures.

Firefighters rescued a woman from a destroyed building and tried to save a seriously injured boy who was pinned under the rubble. A firefighter grabbed the boy's hand and his eyes blinked but he was otherwise still.

Mariupol's streets were empty, with most people sheltering indoors. One man, Aleksander Ivanov, pulled a cart with his possessions while searching for a place to stay after a mortar round destroyed his home.

The city of 430,000 has been without food supplies, running water and electricity for 10 days. Ukrainian officials say about 1,300 people have died, including three in the bombing of a maternity and children’s hospital on Wednesday.

The foreign ministers of Russia and Ukraine met on Thursday in a Turkish resort but weren’t able to find common ground. Russian Foreign Minister Sergey Lavrov said concerns expressed about civilian casualties are “pathetic shrieks” from Russia’s enemies. He even denied that Ukraine has been invaded.


U.S. President Joe Biden will announce Friday that America, along with the European Union and the Group of Seven countries, will move to revoke “most favored nation” trade status for Russia over its invasion of Ukraine. That will allow the U.S. and allies to impose tariffs on Russian imports. Word of the pending announcement comes from an informed source who spoke on condition of anonymity to preview the announcement.

Meanwhile, the U.S. Congress late Thursday approved a $13.6 billion emergency package of military and humanitarian aid for Ukraine and its European allies.

“We promised the Ukrainian people they would not go at it alone in their fight against Putin,” Senate Majority Leader Chuck Schumer, D-N.Y., said just before the vote by the Senate on Thursday. The House passed the bill a day earlier. Biden’s signature is certain.

Around half the money is for arming and equipping Ukraine and for the Pentagon’s costs for sending U.S. troops to other Eastern European nations. Much of the rest includes humanitarian and economic assistance, strengthening regional allies’ defenses and protecting their energy supplies and cybersecurity needs.


Ukrainian President Volodymyr Zelenskyy said 100,000 people have been evacuated during the past two days from seven cities under Russian blockade in the north and center of the country, including the Kyiv suburbs.

But he said the Russian refusal to allow evacuations from Mariupol, a port city in the south, was “outright terror.”

“They have a clear order to hold Mariupol hostage, to mock it, to constantly bomb and shell it,” Zelenskyy said in his nightly video address to the nation.

More than 2.3 million people have fled the war in Ukraine and an estimated 1.9 million are displaced within the country, a U.N. official said Thursday.


The U.N. Security Council will meet on Friday to discuss Russia's claims that the United States is conducting “military biological activities" in Ukraine.

White House press secretary Jen Psaki Psaki called the claim “preposterous.”

“This is all an obvious ploy by Russia to try to justify its further premeditated, unprovoked, and unjustified attack on Ukraine,” Psaki tweeted.

Zelenskyy said the accusation itself is a bad sign.

“That worries me very much because we have often been convinced that if you want to know Russia’s plans, they are what Russia accuses others of,” he said in his nightly address to the nation.


Satellite imagery from Maxar Technologies showed the 40-mile (64-kilometer) line of vehicles, tanks and artillery that had stalled outside Kyiv has been redeployed, with armored units seen in towns near the Antonov Airport north of the city. Some of the vehicles also moved into forests, Maxar reported.

U.S. officials said Ukrainian troops have blasted the convoy with anti-tank missiles.

Ukrainian forces slowed or stopped a Russian advance that was trying to encircle Kyiv from the north to the west, the general staff of Ukraine’s armed forces said Thursday night. It said Ukrainian forces also drove Russians out of Baklanova Muraviika, a village that sits on a road to the capital.

Kyiv Mayor Vitali Klitschko said about 2 million people — half the residents of the Ukrainian capital’s metropolitan area — have left the city, which has become a virtual fortress.

“Every street, every house … is being fortified,” he said in televised remarks. “Even people who in their lives never intended to change their clothes, now they are in uniform with machine guns in their hands.”

Russia has deployed more than 150,000 troops and retains large and possibly decisive advantages in firepower, despite facing fierce Ukrainian resistance and global financial pressure aimed at crippling its economy.

Russian forces on Thursday shelled a nuclear research institute in Ukraine’s second-largest city, Kharkiv, setting buildings on fire, said Anton Gerashchenko, an adviser to the Interior Ministry.

Firefighters managed to extinguish the blazes, but Gerashchenko said a shell hit a building that houses equipment that could release radiation if it were damaged. According to the president’s office, there has been no change in the background radiation.

Russia’s deputy energy minister, Yevgeny Grabchak, said Thursday that power was restored to the decommissioned Chernobyl nuclear plant.

Rafael Grossi, the director-general of the International Atomic Energy Agency, told reporters Thursday in Vienna that the nuclear watchdog had ”scheduled physical inspections” of Ukraine's nuclear facilities, though he would give no details on how or when the inspections would take place.


The Ukrainian government says about 20,000 foreigners have joined the so-called International Legion for the Territorial Defense of Ukraine. They are given weapons to fight when they arrive. Among them are about 100 of the several thousand Americans who asked to join the fight, a Ukrainian official said.

U.S. volunteers are a small subset of foreigners seeking to fight for Ukraine, who in turn comprise just a tiny fraction of the international assistance that has flowed into the country.

Ukraine’s military attaché to Washington, Maj. Gen. Borys Kremenetskyi, said the volunteers are “not mercenaries who are coming to earn money” but are ”people of goodwill who are coming to assist Ukraine to fight for freedom.”

The U.S. government discourages Americans from going to fight in Ukraine, which raises legal and national security issues.

Borys Wrzesnewskyj, a former Liberal lawmaker in Canada who is facilitating recruitment there, said about 1,000 Canadians have applied to fight for Ukraine.


During a televised meeting with Kremlin officials on Thursday, Putin addressed the Western sanctions that have caused the ruble to crash and led many major companies to leave Russia.

“The economy will certainly adapt to the new situation," Putin said.

The list of companies that have stopped operating in Russia grew Thursday, with German fashion brand Hugo Boss temporarily closing its stores and U.S.-based hotel chains Hilton and Marriott closing their Moscow offices, though their Russian hotels are owned and operated by franchisees and will stay open.

Goldman Sachs said it would close its operations in Russia entirely and JPMorgan Chase said it is “unwinding” its Russian banking business.

Meanwhile, Twitter launched a privacy-protected version of its site to bypass surveillance and censorship after Russia restricted access to its service in the country.
