The United Nations Security Council has unanimously adopted a statement voicing "deep concern regarding the maintenance of peace and security of Ukraine," the first such message issued by the body since the war began.

The statement reminds all U.N. members of their responsibility to “settle their international disputes by peaceful means” and express “support of the efforts of the Secretary-General in the search for a peaceful solution.”

The text was drafted by envoys from Norway and Mexico and was agreed upon by all members of the council, including Russia.

The permanent representative from Mexico, Juan Ramón de la Fuente, said it demonstrated all members of the Security Council were “united” in the pursuit of “diplomatic resolution,” although he acknowledged it took over two months to reach this point.

Pressed on whether he thought Russia was earnestly seeking a peaceful end to the war, Ramón de la Fuente said the country demonstrated “a willingness to move in that direction.”

However, the UNSC’s statement is already drawing criticism from those who say it fails to hold Russia accountable for the violence.

U.N. Secretary-General António Guterres said in a statement: "I welcome this support and will continue to spare no effort to save lives, reduce suffering and find the path of peace."

Ukrainian President Volodymyr Zelenskyy will join President Joe Biden and German Chancellor Olaf Scholz in a G-7 virtual leaders meeting on Sunday, White House press secretary Jen Psaki said.

Psaki noted that imposing new sanctions on Russia may also be discussed during the meeting.

“They will discuss the latest developments in Russia's war against Ukraine, the global impact of Putin's war, showing support for Ukraine and Ukraine's future and demonstrating continued G7 unity in our collective response, including building on our unprecedented sanctions to impose severe costs for Putin’s war,” she said.

The meeting will happen the day before Russia’s “Victory Day,” a celebration of the Soviet Union’s defeat of Nazi Germany. Western officials have warned that Russian President Vladimir Putin may ramp up his attacks on Ukraine in the lead up to the day and may want to claim a new victory.

Psaki hinted the administration was intentional about meeting before that day.

“I think it should not be lost the significance or --on anyone the significance of when the timeline when his -- when this G-7 meeting is happening, which is the day before Russia's Victory Day, which President Putin has certainly projected his desire to mark that day as a day where he is victorious over Ukraine. Of course, he's not," she said.

The U.S. shared intelligence with Ukraine that helped it sink the flagship of Russia’s Black Sea fleet, the Moskva, last month, according to two U.S. officials.

The Ukrainians, who have their own intelligence capabilities, had tracked the Moskva independently, though, and the U.S. did not provide "specific targeting information," according to one of the officials.

"We did not provide Ukraine with specific targeting information for the Moskva. We were not involved in the Ukrainians’ decision to strike the ship or in the operation they carried out," Pentagon spokesman John Kirby said in a statement Thursday. "We had no prior knowledge of Ukraine’s intent to target the ship. The Ukrainians have their own intelligence capabilities to track and target Russian naval vessels, as they did in this case."

The U.S. official also noted that: “We do provide a range of intelligence to help the Ukrainians understand the threat posed by Russian ships in the Black Sea and to help them prepare to defend against potential sea-based assaults. Many of the missiles fired at Ukraine have come from Russian ships in the Black Sea, and those ships could be used to support an assault on cities like Odesa.”

NBC News first reported this intel.

White House press secretary Jen Psaki on Friday downplayed the role of U.S intelligence.

"We did not provide Ukraine with specific targeting information for the Moskva. We were not involved in the Ukrainians’ decision to strike the ship or in the operation they carried out. We had no prior knowledge of Ukraine's intent to target the ship," she said. "The Ukrainians have their own intelligence capabilities to track and target Russian naval vessels, as they did in this case. And I’ve discussed this with both our national security adviser and the President and the view is that, one, this is an inaccurate over-claiming of our role and an under-claiming of the role of the Ukrainians who frankly have a greater level of intelligence and access to intelligence than we do."

Still, she said that the U.S. is providing Ukraine with a range of intelligence, which they can use in conjunction with their own findings.

"We do provide a range of intelligence to help them understand the threat posed by Russian ships in the Black Sea and to help them prepare to defend themselves against potential sea-based assaults, but they take our intelligence and they combine that with what they have access to. And so on this specific report, it's just not an accurate depiction of how this happened," she added.

Video circulating online shows explosions and smoke coming from the Azovstal Iron and Steel Works plant in Mariupol.

The footage was released Thursday by the Azov Regiment, a far-right group now part of the Ukrainian military that was among the units defending Mariupol and is holed up inside the Azovstal plant with others. In a statement alongside the video posted on Telegram, the group said that Russian forces were keeping the plant "under heavy fire," using "aircraft, artillery and infantry."

ABC News was unable to verify the date that the video was taken.

In recent days, Ukraine and Russia have offered conflicting accounts of what's taking place at the Azovstal plant. Ukrainian fighters claimed that Russian forces started storming the plant this week, which Russia has denied and instead claimed that its troops have "securely blocked" the sprawling industrial site.

Hundreds of Ukrainian fighters and civilians are said to be trapped inside the Azovstal plant, the last pocket of resistance in Mariupol as Russian forces declare full control over the strategic Ukrainian port city.

Mariupol has not yet fallen, despite Russia's demands that Ukrainian troops defending the besieged Ukrainian port city surrender, according to Ukrainian Prime Minister Denys Shmyhal.

"There [are] still our military forces, our soldiers, so they will fight until the end," Shmyhal told ABC News' George Stephanopoulos in an exclusive interview Sunday on "This Week."

Mariupol is a strategic city for Moscow because it would allow Russian forces in the south to connect with troops in eastern Ukraine's contested Donbas region. It would also give Moscow a key port.

Although Mariupol remains under the Ukrainian government's control, Shmyhal said the city's residents are suffering.

"They have no water, no food, no heat, no electricity," he said. "They ask all of our partners to support and help stop this humanitarian catastrophe."
