The United States' claims that they have intelligence showing China plans to provide weapons to Russia to assist in the ongoing war in Ukraine will impede the "political settlement of the Ukrainian crisis" and "will also further damage" China-US relations, Chinese Foreign Ministry spokesperson Wang Wenbin said during a press conference Thursday.

Wenbin called US claims of intelligence "nothing more than catching up on the wind, slandering and discrediting China."

"Since the outbreak of the crisis in Ukraine, China has been steadfast in dialogue. While standing on peace, it has persuaded and introduced peace in its own way and played a constructive role in resolving the crisis in line with the situation," Wenbin said.

A year into the war in Ukraine, 13 million people have been displaced, including nearly 8 million refugees across Europe and more than 5 million internally displaced in Ukraine, the U.N. High Commissioner for Refugees said in a statement Thursday.

"The vast majority of refugees and internally displaced Ukrainians – some 77% and 79%, respectively – want to return home one day, however, only 12% of both refugees and [internally displaced people] plan to do so in the next three months," the UNHCR said in a press release.

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.
