Filippo Grandi, the UN High Commissioner for Refugees, said in a statement Thursday: “I have worked in refugee emergencies for almost 40 years, and rarely have I seen an exodus as rapid as this one.”
By comparison, it took three months for one million refugees to leave Syria in 2013 when departures there were at their height, according to the UNHCR, the UN Refugee Agency.
Half a million of the refugees are children, according to UNICEF, which warned Europe could be facing its largest refugee crises since World War II.
Millions more people are likely to be forced to flee Ukraine, Grandi said. He added: “International solidarity has been heartwarming. But nothing – nothing – can replace the need for the guns to be silenced; for dialogue and diplomacy to succeed. Peace is the only way to halt this tragedy.”
A resident of Kherson, which has about 300,000 inhabitants, described the situation there as a “humanitarian catastrophe,” telling CNN Thursday there had been chaos and panic in the city as residents tried to get basic necessities.
According to the local resident, there is a severe lack of food and medicine – particularly insulin – with pharmacies being looted.
The resident added that there had been a significant amount of looting by Russian troops, and said that Russian soldiers had been seen arresting men.
The mayor of Kherson, Ihor Kolykhaiev, said Wednesday the Ukrainian military is no longer in the city and that its inhabitants must now carry out the instructions of “armed people who came to the city administration” – indicating that the city has now fallen under Russian control.
In Mariupol, the deputy mayor said on Thursday morning that the southeastern Ukrainian city had faced 26 hours of continued shelling and warned it now faces a humanitarian crisis.
“They are destroying our city with all weapons, from artillery, from airplane bombing, from tactical rockets, from multiple launch rocket systems,” Sergei Orlov told CNN’s “New Day.” “We do not have electricity in the whole city, we do not have water supplies, we do not have sanitary systems, we do not have heating.”
Further north, Ukrainian resistance in the country’s second biggest city, Kharkiv, continues to hold out, as Russian strikes hit at least three schools and damaged a cathedral and shops on Wednesday, according to videos and photos posted to social media, geolocated and verified by CNN.
In a broadcast message Thursday, President Volodymyr Zelensky addressed Russian forces, saying: “You are leaving people without food, you are leaving us without medication. You are shelling evacuation routes, there’s no weapon you would not use against us, against free citizens of Ukraine. “
Most of those who have fled the country have gone to Poland, to Ukraine’s west, with large numbers also entering Hungary, Moldova, Romania and Slovakia. Dramatic video filmed Wednesday showed crowds of people on a platform at Kharkiv train station queuing to get on a train to Uzhgorod, in the west, carrying their children and pets as they fled an assault on the city.
Worryingly, a “big number” of those crossing into Poland are unaccompanied children, according to Poland’s Ambassador to the UN Krzysztof Szczerski. Many children crossing the border are leaving behind parents – particularly their fathers, who have been called by the Ukrainian government to stay behind and fend off Russian troops, he said.
On Thursday, a second round of talks between Russia and Ukraine ended with an agreement on humanitarian corridors for civilians, but Ukraine said there were no breakthroughs beyond that.
Senior Ukrainian official Mykhailo Podoliak said in a tweet: “The second round of negotiations is over. Unfortunately, the results Ukraine needs are not yet achieved. There is a solution only for the organization of humanitarian corridors.”
The head of the Russian delegation, Vladimir Medinsky, outlined some of the two-and-a-half-hour discussion to Russian media.
“We have thoroughly discussed three points – military, international and humanitarian, and the third one is an issue of a future political regulation of the conflict. Both positions are clear and written down. We managed to agree on some of them, but the key thing that we have reached an agreement on today was a matter of rescuing civilians who found themselves in a military clash zone.Russian and Ukrainian Defense Ministries agreed on providing humanitarian corridors for civilians and on a possible temporary ceasefire in areas where evacuation is happening, “Medinsky told journalists.
Another member of the Russian delegation, Leonid Slutsky, told Russia 24 that both sides have agreed on the third round of talks, which will happen in the “nearest future.”
Meanwhile, the Czech government has declared a 30-day state of emergency from Friday in anticipation of a major influx of people fleeing the conflict.
The European Union has made the “historic decision” to grant temporary protection to all refugees fleeing the conflict, said the bloc’s Commissioner for Home Affairs, Ylva Johansson, on Thursday.
The United Nations World Food Program has launched an emergency operation to provide food assistance to people within Ukraine and in neighboring countries following an official request from the Ukrainian government. The organization is calling for $ 570 million to help refugees fleeing violence amid Russia’s ongoing invasion.
Michelle Bachelet, UN High Commissioner for Human Rights, said in a statement Thursday that, in addition to those who had left the country, one million people were displaced internally.
Bachelet said: “Thousands of people, including older people, pregnant women, as well as children and people with disabilities, are being forced to gather in underground shelters and subway stations to escape explosions. Many people in situations of vulnerability are separated from families and effectively trapped. “
With the scale of the humanitarian disaster becoming ever more apparent, the International Criminal Court announced Wednesday it had opened an immediate active investigation into possible war crimes committed by Russian forces in Ukraine.
ICC Prosecutor Karim AA Khan said in a statement Wednesday his office “had already found a reasonable basis to believe crimes within the jurisdiction of the Court had been committed, and had identified potential cases that would be admissible.”
The Russian government has “strongly” rejected accusations that it has committed war crimes in Ukraine.
It’s unclear exactly how many Ukrainian civilians have been killed during the war, but the United Nations Human Rights Monitoring Mission estimates there have been 750 civilian casualties. CNN cannot independently verify these numbers but there are fears of further casualties as Russian strikes hit built-up areas.
On Wednesday, the United Kingdom said it was “gravely concerned” by “reports of the use of cluster munitions” by Russia during its ongoing invasion of Ukraine. And earlier that day, US Ambassador to the UN Linda Thomas-Greenfield said Russia was moving banned weaponry into Ukraine.
“We have seen videos of Russian forces moving exceptionally lethal weaponry into Ukraine, which has no place on the battlefield. That includes cluster munitions and vacuum bombs – which are banned under the Geneva Convention,” she said. Vacuum bombs, or thermobaric bombs are filled with high-temperature, high-pressure explosives and when detonated suck in the oxygen from the surrounding air to generate a powerful explosion and a large pressure wave that can have enormous destructive effects.
He said he feared the push could cause an increase in civilian deaths as cities become ruins.
“I’m afraid to say I do not think we have seen anything yet in terms of the destruction that’s likely to happen,” Shirreff added.
