A planned Russian strike targeting military-industrial facilities will result in countless civilian casualties, Ukrainian President Volodymyr Zelenskyy warned in a new address.

He began his latest speech by saying that on a day recognized by Ukrainians as “Forgiveness Sunday,” there will be no forgiveness for Russia.

“We will not forgive shooting our people and destroying our infrastructure. Hundreds upon hundreds of victims, immeasurable suffering. God will not forgive this, not today, nor tomorrow, never,” Zelenskyy said.

The Russian Ministry of Defense announced on Sunday it will use high-precision weapons to destroy Ukrainian military-industrial facilities.

Zelenskyy warned those sites are in urban areas surrounded by civilian residences. “Hundreds of thousands of people live and work there,” he said. “This will be a premeditated murder, but today I haven’t heard any reaction from any world leader or any politician.”

He said Russia was openly announcing a “planned atrocity” in advance because there is no reaction from the international community.

“Well, I hope you’ll at least say something tomorrow when you’ll see it happened,” Zelenskyy said. “We know exactly how these attacks will be carried out, we know the full chain of command, we know everything, and we’ll forgive nothing.”

Approximately 600 Russian missile launches have taken place since the invasion of Ukraine began on Feb. 24, a senior defense official said.

They could not corroborate any reports of the use of cluster munitions or thermobaric weapons.

Ukrainian air and missile defenses are still effective and in use, the official said, though the airspace over Ukraine is contested.

Both sides have taken losses to aircraft and missile defense inventories, the defense official added, and while they did not reveal exact numbers, they believe both Russia and Ukraine still have a majority of their air defense systems.

The official also said Russian forces are still trying to advance across the north and east of Ukraine but are being met with strong Ukrainian resistance. The convoy is still stalled.

Netflix is the latest company to suspend service in Russia, joining a growing list of Western businesses cutting ties with Russia in protest over the invasion of Ukraine.

The popular streaming service said on Sunday that it is entirely shutting down its service in Russia.

“Given the circumstances on the ground, we have decided to suspend our service in Russia,” a Netflix spokesperson told ABC News.

Variety reported reported on Sunday that Netflix had four Russian original programs in the works, including a crime thriller series directed by Belarus-born director Darya Zhuk.

Netflix's decision follows a list of Western companies suspending operations in Russia. Movie studios Warner Brothers, Sony Pictures and Disney, the parent company of ABC News, have dropped future movie releases in Russia.

Ikea, Mastercard, Visa and American Express have also suspended services to Russia. Microsoft and Apple have ceased all sales, including game consoles and phones, in the country as well.

More than 1 million refugees from Ukraine have fled to Poland since the Russian invasion began on Feb. 24, Poland's Border Guard said on Sunday.

"This is a million human tragedies, a million people banished from their homes by the war," the Border Guard said in a statement on Twitter, noting that its latest tally was from 8 p.m. local time.

Earlier Sunday, Filippo Grandi, the U.N. High Commissioner for Refugees, said more than 1.5 million people have fled Ukraine to multiple neighboring countries since the Russian invasion began, including Romania, Hungary, Moldova and Slovakia.

The Russian forces charging toward Kyiv haven't made progress in the last day as they face Ukrainian resistance and low food and gas supply, a senior U.S. defense official told reporters Tuesday.

However, it could be a deliberate pause, the official said. "Part of the stall could be ... as a result of their own self-determined sort of pause in operations -- that they are possibly regrouping, rethinking, reevaluating," the official said.

The U.S. believes Russian forces "have committed now more than 80% of what was their pre-staged combat power," the official added.

The official said some Russian soldiers weren't told they were going into combat. The official said "not all of them were apparently fully trained and prepared."

The strong Ukrainian resistance has also hurt morale, according to the official.

Russia has now launched more than 400 missiles on Ukraine, the official said. The U.S. believes Russia has launchers that could be used for thermobaric weapons, but cannot confirm their use, the official said.

Russian forces are making the most progress in the south. Russians are attacking Kherson in south Ukraine, which "appears very much to be contested city at this point," the official said.

Russians are also approaching Mariupol in southeastern Ukraine, and while they haven't yet entered the city, "they are close enough now that they could attack Mariupol with long range fires," the official said.

Two towns on the path to Mariupol are believed to be occupied by the Russians, according to the official.

The U.S. believes the Russians hope to move north out of Mariupol up to the heavily-contested city of Kharkiv. The official said they believe Russian forces are trying to encircle Kharkiv.

The U.S. official noted that they've seen "certain risk-averse behavior by the Russian military" over the last week.

"Take the amphibious assault, for instance. They put those troops ashore a good 70 kilometers away from Mariupol because they knew Mariupol was going to be defended and they could put them ashore in an uncontested environment. And they still haven't reached Mariupol," the official said.

"They are not necessarily willing to take high risks with their own aircraft and their own pilots," the official said.

"And of course we're seeing that on the ground -- the fairly slow and steady progress that they have made, and you guys are seeing it for yourselves on the ground where ... units are surrendering, sometimes without a fight."
