President Joe Biden will visit Poland on Feb. 20, on the eve of the first anniversary of the Russian invasion of Ukraine.

Biden will meet with Polish President Andrzej Duda as well as the leaders of the Bucharest Nine, a group of our eastern flank NATO allies, and he’ll deliver remarks to mark the one-year anniversary, White House press secretary Karine Jean-Pierre said Friday.

"President Biden will deliver remarks ahead of the one-year anniversary of Russia's brutal and unprovoked invasion of Ukraine, addressing how the United States has rallied the world, to support the people of Ukraine, as they defend their freedom and democracy, and how we will continue to stand with the people of Ukraine for as long as it takes," Jean-Pierre said.

Romania, a member of NATO, said Friday a Russian missile had come within 22 miles of its border but that it did not cross into the country’s territory, countering a claim made by the Ukrainian military.

"The Romanian Air Forces’ air surveillance system detected on Friday, February 10th, an aerial target launched by a Russian Federation’s ship, navigating in the Black Sea, nearby the Crimean Peninsula. The target is most likely a cruise missile, which flew over the air space of Ukraine and the Republic of Moldova and reentered the Ukrainian air space without ever infringing Romania’s air space," Romanian Defense Minister Angel Tîlvăr said in a statement Friday.

Ukrainian officials had said earlier Friday that two Russian missiles crossed into the airspace of Moldova and Romania before entering Ukraine and being directed at targets in the country.

"Several Russian missiles passed through the airspace of Moldova and Romania. These missiles are a challenge to NATO and collective security. This is terror that can and must be stopped," Zelenskyy said Friday.

A Ukrainian official has confirmed to ABC News that the United States provides coordinates to Ukraine for most strikes carried out in Russian-occupied areas of the country, using the U.S.-supplied HIMARS rocket launchers.

The Washington Post was first to report the news on Thursday, stating in an article: “Ukrainian officials said they require coordinates provided or confirmed by the United States and its allies for the vast majority of strikes using its advanced U.S.-provided rocket systems, a previously undisclosed practice that reveals a deeper and more operationally active role for the Pentagon in the war.”

The Ukrainian official who spoke with ABC News on Friday confirmed that Ukraine’s ability to strike targets with high precision has been thanks to support from the U.S. The official said Ukrainians wanted to get the maximum of out of every HIMARS.

“We get help for maximum effectiveness,” the official added.

And more broadly, the official said the cooperation between Ukraine and the U.S. in the war “is very close.”

Meanwhile, a senior Ukrainian official told ABC News on Friday that The Washington Post’s article “overestimates” the “role of the U.S. in the shooting process” of the HIMARS.

The senior official did not deny that the U.S. is involved in helping the Ukrainian military pinpoint targets with the U.S.-supplied HIMARS, but did not provide further detail.

Russian forces have been firing waves of missiles and drones at energy targets across Ukraine overnight Thursday and throughout Friday morning.

At 10:50 a.m. local time, it was still unclear if the attacks had finished.

Ukraine’s state-run power grid operator Ukrenergo said in a statement that “several objects of high-voltage infrastructure” had been hit in the country’s eastern, western and southern regions, leading to outages in some areas.

The company added that Russian forces also attacked infrastructure sites overnight with lethal attack drones and missiles, “targeting power plants and transmission system facilities.”

ABC News reporters in Kyiv could hear the city’s air defense systems in action mid-morning Friday. At the time, there was no indication that targets had been hit in the capital, though the mayor said debris was reported in one district.

Meanwhile, the mayor of the northeastern city of Kharkiv said a missile had struck there. A regional official in the central city of Kryviy Rih said their critical infrastructure was also hit.

Ukrainian officials said Russian forces attacked the southeastern city of Zaporizhzhia with 17 rockets, targeting energy infrastructure sites there. The mayor of the western city of Khmelnytskyi said their energy infrastructure was also hit.

There were currently no reports of casualties, but Ukrainian officials warned Friday that more Russian missiles could strike.
