Ukraine’s president told Sky News his country cannot stop the war on Russia alone and said nations must act now before it is “too late”.

Speaking to Sky News special correspondent Alex Crawford in the leader’s office in the Ukrainian capital, Volodymyr Zelensky reiterated its call for the West to impose a no-fly zone.

He accused countries of being undecided on the issue of “close” the sky against what he called “the Nazis” – and said of Western nations: “You can’t decide to close or not to close… you can’t decide.

“If you are united against the Nazis and this terror, you must close. Don’t wait for me to ask you several times, a million times. Close the sky.

“Close the skies and stop the bombings,” he said, calling on the world to act faster.

Asked about Western concerns about the potential for a no-fly zone to aggravate the conflict and provoke a direct confrontation with Russia which would escalate it, he replied: “Worse for whom? For our families? No… For “Them…? Who knows? Nobody knows. But we know that’s exactly what’s happening now. And in the future, it will be too late.”

“Believe me, if it goes on like this, you’ll see…they’ll close the sky but we’ll lose millions of people.”

He added: “World War III will begin and only then will you create a no-fly zone – but it will be too late.”

“Colossal Destruction” – What Happened on Day 14?

He said Russian forces ‘can occupy us but you certainly can’t win’, saying Russian President Vladimir Putin was ‘going straight to hell’.

He said NATO allies shouldn’t have to tell Ukrainians who lost their children “Sorry, we didn’t do that yesterday, a week ago. We didn’t push Putin, we we haven’t spoken much with him, we haven’t “I can’t find the dialogue with him. We didn’t do anything and it’s true, yesterday the world didn’t do anything… I’m sorry, but it’s true”.

This comes amid reports of Russian strikes destroyed a maternity ward in one of the most affected cities, Mariupol.

The Ukrainian government said 1,170 civilians have been killed in Mariupol since Russia began his invasion, citing the deputy mayor of the city.

Dmytro Gurin, a Ukrainian MP, challenged NATO and European countries on which line Russia should cross before getting more involved.

He asked, “Is the blood of the Ukrainian people red enough?”

“Putin will not stop at Ukraine and the West could also end up with a war on its territory. Now we have to choose.

“You’ll be asking in two years when they’re bombing infrastructure in the middle of Europe – why haven’t you shut down the skies?”

Would a humanitarian no-fly zone work?

Evelyn Farkas, a former deputy assistant secretary of defense, said a military no-fly zone would be too risky.

However, she added: “A humanitarian no-fly zone does not require anything on the ground or in the air unless it is necessary.

“So some of us called for a humanitarian no-fly zone to enforce humanitarian corridors.”

Ms Farkas admitted that NATO planes would have to attack Russian forces breaking such a rule – but that could be possible because Mr Putin does not want a war with the bloc.

On Poland’s suggestion of handing over jets to donate to Ukraine, she added: “If one option is to provide fighter jets to Ukraine, that is also a potential way to achieve that goal.

“I don’t see it as an escalation. Although every time we have these public debates, Vladimir Putin comes out and makes a statement saying it would amount to a war.

“While he has already said that our economic sanctions are tantamount to waging war on Russia.

“So we really should keep our own council and have these conversations in private – government to government.”

Is Zelenskyy ready to make a deal with Putin?

When asked if he was ready to strike a deal with Mr. Putin, he replied that dialogue is always a compromise.

Ukraine alone cannot end the war, he said. “It’s the decision of two countries and two peoples and the decision of two presidents – and one of them is Putin, so we’ll see.”

And speaking of whether he thinks staying in his role and staying in the country was the right decision, he said he thinks it would be difficult for Ukraine to hold together in the face of the Russian onslaught.

“I think my decision was the right one,” he said. “Who knows. We will see in the future.”

Speaking after days of siege in the southern city of Mariupol, Mr Zelenskyy said Russia was treating Ukrainians like animals by blocking access to basic necessities.

“They want us to feel like animals because they blocked our cities. The biggest cities in Ukraine and they (they) blocked them and because they don’t want our people to receive food, the water.”
