What's happening in Ukraine today and how are countries around the world responding? Read live updates on Vladimir Putin and Russia's invasion of Ukraine.
KYIV, Ukraine -- A regional Ukrainian governor on Tuesday said the Russian bombardment has caused a leak of toxic nitric acid from an industrial facility.
Luhansk Gov. Serhiy Haidai said a Russian air strike on Sievierodonetsk hit a tank with nitric acid at a chemical factory, causing a massive leak of its fumes.
He posted a picture of a huge rose cloud hanging over the city and urged residents not to leave their homes and wear gas masks or make improvised masks from fabric soaked in soda solution.
Sievierodonetsk has been the focus of Russia's offensive in Ukraine's eastern industrial heartland of Donbas.
It has come under intensive artillery barrage and airstrikes as the Russian forces fought Ukrainian troops for control of the city in violent street battles.

WARSAW, Poland -- Poland's Prime Minister Mateusz Morawiecki on Tuesday said the country is on a "good path" to receive new financing from the European Union to support Ukrainian refugees and compensate for weapons Poland gave to Ukraine.
More than 3 million refugees have entered Poland from Ukraine. While some passed through and others returned home, most are still in Poland and receiving government support.
Poland has also been supplying various weapons to Ukraine.
"Albeit slowly, but this (EU) support for Poland is coming and we are on the good path to receive new means for the help for the refugees as well as linked to the weapons that we have handed to Ukraine," Morawiecki said.

BRUSSELS -- Italian Premier Mario Draghi said Tuesday that Italian energy company ENI is able to pay Russia for gas without violating sanctions because Russia considers the payment completed as soon as the euro payment goes through.
"Then it is converted to rubles on the market by an agent of Gazprom, not through the Russian central bank," Draghi said.
He said it appears that Russia has imposed different conditions on different countries, and "in some cases where there were suspensions they asked payments in rubles, period."
ENI also intends to go to a tribunal in Sweden and ask if this form of payment violates the contract. So far the court has not made a ruling, as this just changed last week, Draghi said.

BRUSSELS -- The European Union urged its international partners to avoid placing trade barriers on farm products as Russia's war on Ukraine risks further fueling a possible global food crisis.
"We call on all partners not to restrict trade on agricultural products," European Commission President Ursula von der Leyen said after an EU summit Tuesday in Brussels.
Ukraine has said Russia is blocking the export of 22 million tons of its grain, some of it destined for Africa. African countries imported 44% of their wheat from Russia and Ukraine between 2018 and 2020, according to the UN.
Von der Leyen said the EU is trying to help get food out by road and rail, but land transport assistance might only provide for a fifth of Ukraine's usual monthly exports.
"It is of course more tedious and expensive, but it is necessary to get this wheat out," she said.
Russian President Vladimir Putin has said the EU's sanctions are making things worse. Putin said he's willing to help ease concerns if the restrictive measures are lifted.

KYIV, Ukraine -- Ukraine has welcomed the European Union's decision to block most imports of Russian oil.
"The oil embargo will speed up the countdown to the collapse of the Russian economy and war machine," Foreign Minister Dmytro Kuleba said in a statement.
The Ukrainian Foreign Ministry estimated the ban could cost Russia "tens of billions of dollars" and praised the European Union for "not only making it harder for the Kremlin to finance the (Russian Federation's) aggression but also shoring up its own energy security."

BRUSSELS -- French President Emmanuel Macron vowed France will continue to "fight against impunity" after a French journalist was killed by shell shrapnel while covering a Ukrainian evacuation operation.
The French national anti-terrorism prosecutor's office opened an investigation for war crimes.
Frederic Leclerc-Imhoff, 32, was killed Monday as he was covering a humanitarian operation near Sievierodonetsk, a key city in the Donbas region that is being hotly contested by Russian and Ukrainian forces, according to his employer, French news broadcaster BFM TV.
Macron, speaking after a European summit in Brussels, said "journalists, humanitarian workers must be protected in war zones. Civilians must be protected."
Russia "is breaching all international laws," he said.

BRUSSELS -- Chancellor Olaf Scholz says Germany is working on a deal with Greece that would see Athens deliver old military equipment to Ukraine and get armoured personnel carriers from Germany to fill the gap.
Germany has faced criticism for a perceived reluctance to deliver heavy weapons to Ukraine, which the government rejects. It points among other things to arrangements for NATO allies to deliver older equipment -- particularly of Soviet design -- to Kyiv and then have modern material supplied by Germany.
Scholz pointed Tuesday to an arrangement already made with the Czech Republic. He said he had agreed with Greek Prime Minister Kyriakos Mitsotakis to draw up a similar deal after a European Union summit. He didn't give details, but said it will be finalized by the countries' defense ministries and can be implemented quickly.
Scholz said he also spoke to his Polish counterpart about such arrangements.

BRUSSELS - The chair of the African Union, Senegal's President Macky Sall, has told European Union leaders that Russia's blockade of Ukraine's ports is paving the way for a 鈥渃atastrophic scenario鈥� of widespread shortages and price hikes across his continent.
In an address to leaders gathered in Brussels Tuesday for a summit focused on helping Ukraine, Sall said that a halt to grain and fertilizer exports via the Black Sea is very worrying for a continent hosting 282 million undernourished people. He said that the price of fertilizer across Africa has already tripled compared to 2021.
鈥淎ccording to some estimates, cereal yields in Africa will fall by 20 to 50 percent this year,鈥� Sall said. 鈥淲e would like to see everything possible done to free up available grain stocks and ensure transportation and market access.鈥�
Charles Michel, the EU Council president, said that 鈥渢he EU is sparing no efforts to free Ukraine's exports over land and exploring alternative sea routes.鈥�
African countries imported 44% of their wheat from Russia and Ukraine between 2018 and 2020, according to UN figures. The African Development Bank is already reporting a 45% increase in wheat prices on the continent.

MOSCOW -- The deputy head of Russia's Security Council is alleging that sanctions against the country, including new measures targeting oil exports, are aimed at hurting ordinary Russians and motivated by hatred.
Dmitry Medvedev, who is also a former president and prime minister, wrote on Telegram Tuesday that sanctions don't affect the Russian political elite and won't be 鈥渇atal鈥� for big business, but are 鈥渄irected precisely against the people of Russia.鈥�
He claimed that measures affecting oil and gas are aimed at forcing the government to introduce budget cuts.
鈥淎n embargo on buying oil and gas from Russia? The same thing: to reduce the budget incomes and force the state to abandon its social obligations鈥� such as raising payments in line with inflation, he wrote.
The European Union has agreed on a ban affecting all Russian exports of oil by sea to the EU, but not by a key pipeline to some Central and Eastern European countries including Hungary. The EU hasn't introduced an embargo on Russian gas.
After listing sanctions in various sectors, Medvedev wrote, 鈥淭hey hate us all! The basis for these decisions is hatred for Russia, for Russians and for all its inhabitants.鈥�

COPENHAGEN, Denmark - The Norwegian Refugee Council says thousands of civilians caught in Sievierodonetsk are 鈥渋n dire need of aid.鈥� It is calling for humanitarian organizations to be allowed to access the eastern Ukrainian city 鈥渨ith lifesaving assistance and to enable safe evacuations of civilians who wish to leave.鈥�
The council's secretary-general, Jan Egeland, said Tuesday: 鈥淲e fear that up to 12,000 civilians remain caught in crossfire in the city, without sufficient access to water, food, medicine or electricity.鈥� He added that 鈥渢he near-constant bombardment is forcing civilians to seek refuge in bomb shelters and basements,鈥� with 鈥渙nly few precious opportunities鈥� to escape.
He added that the organization 鈥渃annot save lives under the hail of grenades.鈥�

KYIV, Ukraine -- The mayor of Sievierodonetsk says Russian forces have taken around half of the city in eastern Ukraine.
Oleksandr Striuk told The Associated Press in a phone interview Tuesday that heavy fighting is ongoing and artillery bombardments threaten the lives of the thousands of civilians still sheltering in the ruined city.
鈥淗alf of the city has been captured by the Russians and fierce street fighting is under way,鈥� Striuk said. 鈥淭he situation is very serious and the city is essentially being destroyed ruthlessly block by block.鈥�
He added that 鈥渢he Ukrainian military continues to resist this frenzied push and aggression by Russian forces.鈥�
Striuk estimated that around 13,000 people remained in the city out of a pre-war population of around 100,000 but said it was impossible to keep track of civilian casualties amid round-the-clock shelling. He said more than 1,500 people in the city who died of various causes have been buried since the war began in February. Evacuation efforts have been halted because of the danger of shelling.
He said that 鈥渃ivilians are dying from direct strikes, from fragmentation wounds and under the rubble of destroyed buildings, since most of the inhabitants are hiding in basements and shelters.鈥�

ISTANBUL - Turkey's foreign minister says Russian Foreign Minister Sergey Lavrov will visit Turkey on June 8 for talks that will address among other things opening a Black Sea corridor for Ukrainian grain exports.
Turkish Foreign Minister Mevlut Cavusoglu also said in a video interview Tuesday with the state-run Anadolu news agency that the French and German ambassadors had been summoned to the Foreign Ministry over demonstrations in their countries by groups considered to be terrorist by Ankara.
Turkey has said activities of the Kurdistan Workers' Party, or PKK, are one of its objections to Sweden and Finland joining NATO. The PKK is designated a terrorist organization by the European Union and U.S.

KYIV, Ukraine -- A court in Ukraine has convicted two Russian soldiers of war crimes for the shelling of civilian buildings and sentenced both to 11 1/2 years in prison. Tuesday's verdict concluded the country's second war crimes trial since the Russian invasion started.
Russian servicemen Alexander Bobykin and Alexander Ivanov were charged with violating the laws and customs of war over the shelling of civilian infrastructure in the Kharkiv region on the first day of the Russian attack on Ukraine. They both stood trial in a court in Ukraine's Poltava region and pleaded guilty to the charges.
Earlier this month, a court in Kyiv sentenced a 21-year-old Russian soldier to life in prison for fatally shooting a Ukrainian civilian in the first war crimes trial since Russia invaded.

COPENHAGEN, Denmark -- Denmark says its embassy in Moscow will no longer accept applications for visas or residence permits. It's citing a staff shortage after Russia expelled four diplomats and three other employees earlier this month.
The Foreign Ministry said Tuesday that 鈥渋t is not possible to maintain the usual level of activity.鈥� It said it wants to prioritize giving assistance to Danish citizens. It said that the move was temporary, but didn't specify how long it will last.
Moscow's tit-for-tat move came after Denmark in April expelled 15 Russian embassy employees, identified as intelligence officers, from the diplomatic mission in Copenhagen in line with similar steps taken by other European Union countries.
The Netherlands also shut down its visa department in Moscow because staff were expelled.
The leader of Russia-backed separatists who control part of Ukraine's eastern Donetsk region says his administration will nationalize some of the ships in the port of Mariupol.
Denis Pushilin was quoted by Russian state news agency RIA Novosti on Tuesday as saying that 鈥渟ome of the vessels will come under the jurisdiction of the Donetsk People's Republic. The relevant decisions have been made.鈥� It wasn't immediately clear whether he was referring to Ukrainian vessels or ships from other countries.
Kyiv has accused Russia of blocking its sea ports and hindering grain exports, fueling a global food crisis. Moscow has sought to pin the blame on the West and the sanctions it imposed on Russia.
Russian forces encircled Mariupol, a strategic port city on the Azov Sea, early in the war. They took full control of it this month after capturing nearly 2,500 Ukrainian fighters who had been holed up in the sprawling Azovstal steel mill, the last remaining pocket of Ukrainian resistance.

BRUSSELS - After securing a compromise overnight to slap an embargo on most Russian oil imports, European Union leaders will focus Tuesday on how to help Ukraine export millions of tons of grain blocked by the war.
The leaders will call on Russia to halt its attacks on transport infrastructure in Ukraine and lift its blockade of Black Sea ports so that food can be shipped out, notably from Odesa.
Ukraine says Russia has prevented the export of 22 million tons of its grain and is fueling a global food crisis. The UN says African countries imported 44% of their wheat from Russia and Ukraine between 2018 and 2020.
Russian President Vladimir Putin says the EU's sanctions are making things worse. Putin says he's willing to help ease concerns if the restrictive measures are lifted.
The EU leaders are likely to call for a speedier effort to set up 鈥渟olidarity lanes鈥� and to help Ukraine get its grain out through European land routes and sea ports.

KYIV, Ukraine - A Ukrainian regional governor says an overnight missile strike on the city of Sloviansk in the eastern Donetsk region killed at least three people and wounded six more.
Donetsk governor Pavlo Kyrylenko said in a Facebook post on Tuesday morning that a school and at least seven multi-storey buildings were damaged.
In the neighboring Luhansk region, where Russian forces are attempting to take the city of Sievierodonetsk, two people were killed and four wounded by shelling, Luhansk governor Serhiy Haidai said on Telegram on Tuesday. He didn't say when the shelling occurred.

THE HAGUE, Netherlands - Representatives of a group of nations working together to investigate war crimes in Russia's invasion of Ukraine are meeting in The Hague amid ongoing calls for those responsible for atrocities to be brought to justice.
Tuesday's co-ordination meeting at the European Union's judicial cooperation agency, Eurojust, of members of a Joint Investigation Team and International Criminal Court Prosecutor Karim Khan comes as Russian forces continue to pound Ukrainian towns.
Moscow's invasion of Ukraine has been widely condemned as an illegal act of aggression. Russian forces have been accused of killing civilians in the Kyiv suburb of Bucha and of repeated attacks on civilian infrastructure including hospitals and a theatre in the besieged city of Mariupol that was being used as a shelter by hundreds of civilians. An investigation by The Associated Press found evidence that the March 16 bombing killed close to 600 people inside and outside the building.
Since Russia invaded Ukraine on Feb. 24, the AP and PBS series Frontline have verified 273 potential war crimes.

ISTANBUL - Turkish President Recep Tayyip Erdogan's office says he has stressed the need to set up a corridor for Ukrainian agricultural products in a phone call with Ukraine's President Volodymyr Zelenskyy.
Ukraine says Russia's blockade of its Black Sea ports is preventing the supply of millions of tons of grain around the world.
Erdogan's office said late Monday he told his Ukrainian counterpart that he 鈥渁ttaches particular importance鈥� to securing safe passage for ships carrying agricultural exports.
He also wants Turkey to be part of an Istanbul-based 鈥渃ontrol center鈥� including Ukraine, Russia and the United Nations to find a way to end the war.
Earlier Monday, Erdogan spoke to Russian President Vladimir Putin. A readout of that call from Erdogan's office referred to an 鈥渙bservation mechanism鈥� involving Turkey, Ukraine, Russia and the UN. No further details were given.

POKROVSK, Ukraine - Across eastern Ukraine, hospitals in cities and towns near the front lines of Russia's war are increasingly coming under pressure.
Many staff have fled and those who remain have to deal with an influx of war wounded on top of their usual flow of sick patients. One lifeline for the overstretched hospitals is a specially equipped evacuation train run by the medical charity Doctors Without Borders.
It includes an intensive care unit and ferries the wounded and the sick westward to better equipped hospitals in safer parts of the country.
One surgeon in the eastern city of Kramatorsk says medical workers are facing 鈥渢he most terrible nightmare鈥� of treating civilians who have been wounded in Russian attacks including children with their limbs blown off.
