Some 3,000,381 people have so far left Ukraine, data from the U.N. Refugee Agency (UNHCR) showed. It is basing its aid plans on 4 million refugees but has said the figure will likely increase.
After Sunday's Russian strike on the Yavoriv military base near Lviv, some people from western Ukraine have now joined the refugee flow across the border.

"Everybody considered West Ukraine to be quite safe until they started striking Lviv," said Zhanna, 40, a mother from Kharkiv, who was heading to Poland to reunite with her godmother who left Ukraine a few days earlier.
"We left Kharkiv for Kirovohrad," she said at the train station of Przemysl, the nearest town to Poland's busiest border crossing with Ukraine. "We wanted to stay there. We did not want to go abroad."

All trade with Russia must be stopped! So that it can't sponsor the killing of our children. Ukrainians all over the world! Contact politicians, talk to journalists, put pressure on business to leave the Russian market. So that their dollars & euros aren’t paid for our blood

16:17: Nearly a hundred children have died in Russia's invasion of Ukraine, President Volodymyr Zelenskiy told Canadian lawmakers on Tuesday, adding that the southern Ukrainian city of Mariupol was left without means of communication and was nearly running out of food and water.
"Currently we have 97 children that died during this war", Zelenskiy said in a virtual address to Canadian lawmakers.
"They destroying everything: memorial complexes, schools, hospitals, housing complex. They already killed 97 Ukrainian children. We are not asking for much. We are asking for justice, for real support", the Ukrainian president said.
Zelenskiy's address began and ended with standing ovations from Canadian lawmakers. The Ukrainian president reiterated that Canada and other Western countries should impose more sanctions on Russia and do more to help Ukraine, including by imposing a no-fly zone over Ukraine.
"How many cruise missiles have to fall on our cities?" Zelenskiy asked as he repeated his appeal for the no-fly zone.
Western countries have been swiftly moving to isolate Russia from world trade and the global financial system as a result of its invasion but the U.S. government has ruled out a no-fly zonewhich it says would risk direct conflict with nuclear-armed Russia.
Mariupol was "left without heat or hydro, without means of communicating, almost without food, without water", Zelenskiy added.
Zelenskiy has sought to drum up support for Ukraine with video briefings of foreign audiences that have included the European and British parliaments. He is also due to address the U.S. Congress on Wednesday.
14:19: NATO is concerned Russia might use chemical weapons in a "false flag" attack as part of its invasion of Ukraine, NATO Secretary-General Jens Stoltenberg said on Tuesday.
"We are concerned Moscow could stage a false flag operation in Ukraine, possibly with chemical weapons," Stoltenberg told a press conference.

1.10pm: President Alexander Lukashenko said on Tuesday that Belarus had intercepted a missile fired at it two days ago from Ukraine, but that it would resist what he called attempts to draw it into the conflict across the border.
The Kyiv government accused Russia on Friday of staging "false flag" air attacks on Belarus from Ukraine to provide an excuse for Moscow's close ally, which has served as a staging post for Russian forces entering Ukraine, to join the conflict itself.

Two large blasts echoed across the centre of the city just before dawn on Tuesday. Late on Monday, tracer bullets flashed across the night sky as Ukrainian forces apparently targeted an enemy drone.
"Today is a difficult and dangerous moment," mayor Vitali Klitschko said.
"The capital is the heart of Ukraine, and it will be defended. Kyiv, which is currently the symbol and forward operating base of Europe's freedom and security, will not be given up by us."
11.55am: Ukraine planned to make a new attempt to deliver supplies to the besieged city of Mariupol on Tuesday as the first convoy of civilians allowed out by Russia reached safety and the Red Cross issued a dire warning about the situation.
People trapped in Mariupol by Russian shelling were "essentially being suffocated in this city now with no aid," Ewan Watson, spokesperson of the International Committee of the Red Cross (ICRC), told a UN briefing in Geneva.
Residents have been without heating, electricity and running water for most of the past two weeks, the Ukrainian authorities say.
11.35am: New British legislation which came into effect overnight will allow the government to speed up its efforts to root out Russian "dirty money" parked in British assets, finance minister Rishi Sunak said on Tuesday.

10.05am:The Kremlin said on Tuesday that it was too early to make predictions about the possible results of talks between Russia and Ukraine.
"The work is difficult and in the current situation the very fact that they are continuing is probably positive," Kremlin spokesman Dmitry Peskov told reporters.
"We don't want to make predictions. We await results."
Russia, Peskov said, was disappointed that Western officials had made no public statements about the killing of more than 20 people in the separatist-controlled city of Donetsk in eastern Ukraine.
Russia on Monday accused Ukraine of carrying out a missile attack on the city. Ukraine denied it and said the rocket used in the attack was Russian.
9.50am: Britain on Tuesday said it would ban the export of luxury goods to Russia and impose new tariffs on £900 million (€1.06 billion) worth of Russian imports, including vodka.

9.35am: A curfew will be imposed on the Ukrainian capital Kyiv from 8 pm (6pm GMT) on Tuesday to 7am (5am GMT) on Thursday after several apartment blocks were struck by Russian forces based outside the city, Mayor Vitaliy Klitschko announced.
Two people were killed in the latest bloodshed, he said.
"It is prohibited to move around the city without special permission, except to go to bomb shelters," Klitschko said.
"The capital is the heart of Ukraine, and it will be defended. Kyiv, which is currently the symbol and forward operating base of Europe’s freedom and security, will not be given up by us."
9.15am: The governor of Ukraine's southern region of Mykolayiv said the security situation was calmer in the area on Tuesday because Russian forces had been pushed back slightly from the regional capital, which they have been trying to seize.
In an interview on national television, governor Vitaliy Kim said Russian troops continued to fire at the city of Mykolayiv and that 80 people were wounded on Monday, including two children.
"You can be 99 per cent sure that Mykolayiv region will continue to hold back the advance of the Russian troops. There is the Bug River, which they need to force their way across in order to advance," he said. "
We will not give up the bridges to the invaders."
9am: The European Union formally approved on Tuesday a new barrage of sanctions against Russia for its invasion of Ukraine, which include bans on investments in the Russian energy sector, luxury goods exports and imports of steel products from Russia.

8.45am: An adviser to Ukrainian president Volodymr Zelenskiy said on Tuesday that the war in Ukraine was at a crossroads that could lead to an agreement at talks with Russia or a new Russian offensive.

8.3oam: The latest package of EU sanctions against Russia do not affect Hungary's energy supplies and oil and gas group MOL can also continue crude production in the BaiTex field in Russia, Hungary's foreign minister said on Tuesday.

8am: Ukraine will make a new attempt to deliver supplies to civilians trapped in the encircled city of Mariupol on Tuesday, Deputy Prime Minister Iryna Vereshchuk said.

7.30am: Russia's defence ministry spokesperson Igor Konashenkov on Tuesday said Russian forces had taken full control of all territory in Ukraine's southern Kherson region, Russian news agencies reported.

Reuters could not verify the reports independently.

Officials from Russia and Ukraine are set to engage in another round of diplomatic talks as Moscow’s forces continue to pound away at the Ukrainian capital Kyiv and other cities across the country.
Shortly before dawn on Tuesday, large explosions thundered across the capital while Russia pressed its advance on multiple fronts.
Elsewhere, a convoy of 160 civilian cars left the encircled port city of Mariupol along a designated humanitarian route, the city council reported, in a rare glimmer of hope a week and a half into the lethal siege that has pulverised homes and other buildings and left people desperate for food, water, heat and medicine.
The latest negotiations, held via video conference, were the fourth round involving higher-level officials from the two countries and the first in a week. The talks ended on Monday without a breakthrough after several hours, with an aide to Ukrainian president Volodymyr Zelenskiy saying the negotiators took “a technical pause” and planned to meet again on Tuesday.
The two sides had expressed some optimism in the past few days.
Mykhailo Podolyak, the aide to Mr Zelensky, tweeted that the negotiators would discuss “peace, ceasefire, immediate withdrawal of troops & security guarantees”.
Previous discussions, held in person in Belarus, produced no lasting humanitarian routes or agreements to end the fighting.
In Washington, White House press secretary Jen Psaki said that while the Biden administration supports Ukraine’s participation in the talks with Russia, Russian president Vladimir Putin would have to show signs of de-escalating in order to demonstrate good faith.
Overall, nearly all of the Russian military offensives remained stalled after making little progress over the weekend, according to a senior US defence official who spoke on condition of anonymity to discuss the Pentagon’s assessment.
Russian troops were still about nine miles (15 kilometres) from the centre of Kyiv, the official said.
The official said that Russian forces have launched more than 900 missiles, but that Ukraine’s airspace is still contested, with Russia not achieving total air superiority.
Ukrainian authorities said two people were killed when the Russians struck an airplane factory in Kyiv, sparking a large fire. The Antonov factory is Ukraine’s largest aircraft plant and produces many of the world’s biggest cargo planes.
Russian artillery fire also hit a nine-storey apartment building in the northern Obolonskyi district of the city, killing two more people, authorities said.
And a Russian airstrike near a Ukrainian checkpoint caused extensive damage to a downtown Kyiv neighbourhood, killing one person, Ukraine’s emergency agency said.
In an area outside Kyiv, Fox News reporter Benjamin Hall was injured while reporting and taken to hospital, the network said.
In Russia, the live main evening news program on state television was briefly interrupted by a woman who walked into the studio holding a poster against the war. The OVD-Info website that monitors political arrests said she was a Channel 1 employee who was taken into police custody.
A town councillor for Brovary, east of Kyiv, was killed in fighting there, officials said. Shells also fell on the Kyiv suburbs of Irpin, Bucha and Hostomel, which have seen some of the worst fighting in Russia’s stalled attempt to take the capital, local authorities said.
Airstrikes were reported across the country, including the southern city of Mykolaiv, and the northern city of Chernihiv, where heat was knocked out to most of the town. Explosions also reverberated overnight around the Russian-occupied Black Sea port of Kherson.
Nine people were killed in a rocket attack on a TV tower in the western village of Antopol, according to the region’s governor.
In the eastern city of Kharkiv, firefighters doused the smouldering remains of a four-storey residential building. It was unclear whether there were casualties.
In Mariupol, where the war has produced some of the greatest suffering, the city council did not say how many people were in the convoy of cars headed westward for the city of Zaporizhzhia. But it said a ceasefire along the route appeared to be holding.
Previous attempts to evacuate civilians and deliver humanitarian aid to the southern city of 430,000 were thwarted by fighting.
Ukraine’s military said it repelled an attempt on Monday to take control of Mariupol by Russian forces, who were forced to retreat. Satellite images from Maxar Technologies showed fires burning across the city, with many high-rise apartment buildings heavily damaged or destroyed.
The Kremlin-backed leader of the Russian region of Chechnya said on a messaging app that Chechen fighters were spearheading the offensive on Mariupol.
Robert Mardini, director-general of the International Committee of the Red Cross, said the war has become “nothing short of a nightmare” for those living in besieged cities, and he pleaded for safe corridors for civilians to leave and humanitarian aid to be brought in.
The Russian military said 20 civilians in the separatist-controlled city of Donetsk in eastern Ukraine were killed by a ballistic missile launched by Ukrainian forces. The claim could not be independently verified.
The UN has recorded at least 596 civilian deaths since Russia invaded Ukraine on February 24, though it believes the true toll is much higher. Millions more have fled their homes, with more than 2.8 million crossing into Poland and other neighbouring countries in what the UN has called Europe’s biggest refugee crisis since the Second World War.
